Sectors of Erebus

Overview:
Niflheim (Sector 2) is the nerve center of Erebus’s security state—a subterranean realm of shadow, silence, and surveillance. Directly north of Agartha and accessible via armored maglev corridors, Niflheim is where order is enforced, dissent is crushed, and the machinery of Astraea’s control is both maintained and perfected. Its labyrinthine complexes house the headquarters of the Directorate’s Internal Security Division, interrogation sites, detention vaults, and the planet’s most sophisticated surveillance apparatus. In Niflheim, fear is a tool, and loyalty is a currency.

Geography & Location

Niflheim is carved into one of Erebus’s oldest basaltic ridges, its structures descending through layers of ancient volcanic rock. Above ground, the sector is marked by imposing security towers, armored maglev lines, and the sealed entrances to fortified bunkers. The sector’s deep, cold corridors are kept deliberately austere—dimly lit, echoing with the hum of monitoring equipment, and lined with polished black stone.
Strategically, Niflheim forms a defensive bulwark for Agartha, and its maglev junctions are designed for rapid lockdown or military deployment in the event of crisis.

Major Facilities & Districts

• The Citadel:
  The central fortress and command center of Internal Security. Heavily guarded and nearly impenetrable, it contains the sector’s main administration, intelligence analysis hubs, and the Black Archive—a data vault of all recorded dissent and subversion.

• The Watchtower Complex:
  A cluster of surveillance control rooms, drone bays, and monitoring stations. Here, security analysts review thousands of live feeds from across Erebus, flagging anomalies and dispatching patrols at a moment’s notice.

• The Hall of Interrogation:
  A notorious subterranean block where suspects are brought for “questioning.” Equipped with high-security cells, psychological manipulation chambers, and advanced lie-detection technology, it is the last stop for many accused of treason.

• The Ministry Quarters:
  Administrative and residential area for high-ranking security officials and their families. Life here is privileged but tense; status is always temporary, and trust is in short supply.

• The Re-education Vaults:
  Secure facilities where political dissidents, “malcontents,” and failed officials undergo forced indoctrination, psychological conditioning, or, in the worst cases, disappear entirely.

• The Obsidian Yards:
  Maintenance and deployment zone for security drones, armored vehicles, and riot-control units. The Yards operate day and night, ready for swift mobilization against unrest.

Society & Culture

In Niflheim, secrecy and vigilance define every aspect of daily existence. The Directorate’s Internal Security Division, led by the feared Chief Overseer Anton Liang, maintains supreme authority. Residents are almost exclusively security personnel, analysts, and their families—handpicked for loyalty, discipline, and psychological resilience.

Children are raised with rigorous indoctrination into the values of order and sacrifice. Social life revolves around state rituals, loyalty ceremonies, and competitive internal rankings. Paranoia is cultivated: neighbors watch each other, and even minor infractions can lead to review by the Watchtower’s analysts.

Despite the oppressive atmosphere, there is an undercurrent of pride among Niflheim’s residents. They see themselves as Erebus’s shield—protectors of civilization against chaos, rebellion, and foreign subversion.
Rumors persist, however, of secret fraternities, encrypted message rings, and even the occasional act of sabotage by those who have seen too much.

Notable Locations

• The Citadel: Fortress-headquarters of Internal Security.
• Black Archive: Vast, restricted vault of surveillance records and intelligence.
• The Watchtower Floor: Nerve center for planetary surveillance and drone operations.
• Interrogation Chamber 7: Infamous for “breaking” even the most stubborn dissidents.
• The Loyalty Garden: A grimly beautiful indoor park where security families gather for state-sanctioned leisure under the ever-watchful eyes of surveillance orbs.

Current Climate

Recent unrest in the Underworks and rising rumors of the Long Insurgence have put Niflheim on high alert. Chief Overseer Anton Liang has doubled patrols and instituted random loyalty audits throughout the sector. Every whisper, every glance, every anomaly is recorded and analyzed. Morale is brittle; the pressure to maintain perfect order is unrelenting, and the fear of internal betrayal is ever-present.

In Niflheim, the shadows have eyes, and safety—and survival—depend on unwavering obedience.

Notable Residents of Niflheim

Eun Ji-Ho
Ministry Quarter Administrator. Eun manages housing and privileges for Niflheim’s elite, walking the knife edge between pleasing her superiors and protecting her staff from the sector’s unforgiving politics.

A city of shadows and secrets, Niflheim – Sector 2 is where the fate of rebels and loyalists alike is decided—often before they even realize they were watched.

Overview:
Tartarus (Sector 3) is the industrial soul and laboring backbone of Erebus—a vast, subterranean expanse where the relentless extraction and transformation of the planet’s mineral wealth fuels the survival of civilization. Stretching beneath a jagged range of ancient volcanic mountains southeast of Agartha, Tartarus is a world of roaring furnaces, labyrinthine mines, and sprawling manufactories. Here, the air is thick with smoke and the stench of sweat; the rhythm of life is set by the pounding of forges and the barked orders of overseers. Tartarus is where Astraea’s promises of progress are built—and where its harshest sacrifices are demanded.

Geography & Location

Tartarus is situated in the southeastern industrial belt of Erebus, directly connected to Agartha and Sheol by heavily used maglev lines. Its upper levels house the largest foundries and processing plants, while its lower strata descend into a tangled web of mines—some centuries old, others newly blasted into the bedrock in search of fresh veins.

The sector’s landscape is dominated above ground by a sprawling complex of smokestacks, slag heaps, and armored freight yards. Subterranean Tartarus is a multi-layered maze: at the top, the Forge Galleries and Assembly Halls; below, the Deep Mines and the Iron Tunnels; and deeper still, rumored “black pits” where no laborer willingly treads.

Major Facilities & Districts

• The Central Foundry:
  The largest and oldest industrial complex on Erebus, this tiered foundry refines ores and produces the heavy machinery, vehicle parts, and structural components that underpin all major planetary infrastructure. Its legendary Inferno Hall can be seen glowing red from miles away.

• The Assembly Halls:
  A series of vast, automated manufactories where everything from maglev carriages to mining exosuits is assembled. Work here is grueling, repetitive, and tightly monitored for efficiency.

• The Deep Mines:
  The sector’s literal and metaphorical underworld, these mines burrow for miles beneath the surface. Laborers endure brutal conditions and ever-present danger from cave-ins and gas leaks. The Obsidian Vein is the most valuable—and deadliest—mining shaft in the sector.

• The Overseers’ Spire:
  A stark, reinforced tower rising from the center of the sector, home to Astraea-appointed managers, security detachments, and administrative offices. From here, quotas are set and punishments decreed.

• The Hecate Dormitories:
  Worker barracks arrayed in regimented blocks. Each is cramped, noisy, and perpetually under surveillance. The rare “model dormitory” is used for propaganda tours; most are grim and overcrowded.

• The Black Market Tunnels:
  An illicit network of passageways connecting the lower mines and worker quarters. Here, laborers trade for contraband, stolen parts, or even forbidden literature—always at risk of a raid by sector security.

Society & Culture

Life in Tartarus is defined by unyielding discipline, relentless quotas, and the constant threat of punishment for failure. The sector’s population is overwhelmingly made up of laborers—miners, machinists, smelters—alongside a smaller caste of skilled engineers and Astraea-appointed foremen.

Work is organized by the shift bell, and days blur into nights in the perpetual artificial light of the foundries. Accidents are common; injuries and “industrial disappearances” are quietly accepted as the cost of progress.
Despite the hardship, a fierce solidarity exists among the workers—expressed in whispered songs, coded graffiti, and the sharing of food and tools. Legends of heroic labor martyrs circulate, inspiring both pride and the seeds of resistance.

Social mobility is almost nonexistent. Promotions are rare and often political. The children of laborers are expected to follow in their parents’ footsteps, learning the trade (and the rules) from a young age.
Festivals are permitted only when quotas are exceeded; most are appropriated as loyalty rallies by Astraea management.

Notable Locations

• Inferno Hall: Heart of the Central Foundry, known for its breathtaking—and deadly—molten metal cascades.
• The Obsidian Vein: Infamous deep mine, source of rare minerals and countless tragedies.
• Overseers’ Spire: Nerve center of sector authority and discipline.
• The Laborers’ Shrine: An unofficial, candle-lit alcove in the dormitories where workers leave offerings to the memory of the “Nameless Martyr.”
• The Boilerhouse Baths: Communal baths and rare place of respite, where grievances and gossip are exchanged in the steam.

Current Climate

Tartarus is under mounting strain. Recent failures to meet Etherium shipment quotas have led to harsher working conditions and increased security crackdowns. Rumors of sabotage, “ghost shifts” (secret resistance cells), and unexplained disappearances are on the rise. Management has brought in new overseers from Niflheim and installed more surveillance, but morale is at a breaking point.
The sector’s legendary productivity is matched only by its simmering unrest—making Tartarus a powder keg, one spark away from open revolt.

Notable Residents of Tartarus

Gregor Malkov
Chief Sector Overseer. Malkov is a hard-nosed manager with a reputation for unbreakable discipline and creative cruelty. He is both feared and despised by the labor force.

Nadia Reyes
Union Mediator. Officially, Nadia is tasked with resolving labor disputes; unofficially, she is a lifeline for desperate workers and a suspected sympathizer with resistance movements.

Yuri Takeda
Lead Engineer. Responsible for keeping the Central Foundry running despite chronic breakdowns and resource shortages. Brilliant but exhausted, he is rumored to be developing new safety protocols—against management’s wishes.

Lysander Wu
Foreman of the Obsidian Vein. A survivor of three cave-ins, Wu is regarded as both lucky and cursed; his crew are fiercely loyal, and he is quietly respected even by the Overseers.

“Red” Marisol Vega
Black Market Queen. Marisol runs the largest underground supply network in the sector, trading in everything from extra rations to forbidden books. She is wanted by sector security but always seems one step ahead.

Petros Demetrios
Boilerhouse Attendant and folk poet. Petros’s songs and stories circulate among the workers, keeping hope alive in the hardest shifts. He is a symbol of Tartarus’s stubborn spirit.

In Tartarus, the fires never stop burning—and neither does the will to endure, or to fight for a future beyond the reach of Astraea’s shadow.

Overview:
Sheol (Sector 4) is the teeming heart of Erebus’s working class—an immense complex of subterranean habitation, industrial-scale food processing, and relentless bureaucracy. Sprawling west of Tartarus and southwest of Agartha, Sheol is where the masses of laborers, administrators, and their families live, eat, and struggle for survival. Here, the rhythm of life is dictated by rationing, shift bells, and the endless shuffle of paperwork. To live in Sheol is to dwell in perpetual twilight, hemmed in by the demands of the system and the ever-watchful eye of Astraea’s civil authorities.

Geography & Location

Sheol is carved into a series of stacked caverns and honeycombed tunnels, spreading horizontally and vertically through a soft metamorphic rock basin. The sector’s upper levels are reserved for food production and administrative offices, while the middle tiers hold vast living blocks. The lowest levels descend into the “gutter zones,” where failed projects, derelict machinery, and the most desperate citizens are left to fend for themselves.

Maglev lines connect Sheol to Tartarus, Agartha, and Helheim, but sector borders are tightly controlled by civil security checkpoints. Above ground, only the occasional air vent or hydroponic dome hints at the life below.

Major Facilities & Districts

• The Census Hall:
  The administrative brain of Sheol, handling everything from employment assignments to ration distribution. Endless lines of citizens wind through its fluorescent-lit corridors, clutching identification chips and work permits.

• The Rationworks:
  A sprawling complex of hydroponic farms, protein-vat factories, and recycled water plants. Here, food is grown, synthesized, and processed for the entire sector (and exported to other sectors in crisis).

• The Living Blocks:
  Monolithic residential towers, each housing thousands. Apartments are cramped, uniform, and constantly monitored. The “Greenlight” block is famed for its rare communal gardens, while the “Old Iron” block is notorious for blackouts and unrest.

• The Gutter Zones:
  Blighted, semi-abandoned lower levels where the poor, the jobless, and the system’s rejects eke out precarious lives. The Directorate rarely ventures here except for periodic sweeps.

• The Registry:
  A fortified data center that tracks every resident’s work history, ration status, and family ties. The Registry’s records are law—an error here can doom a family to starvation or exile.

• The Community Forum:
  The closest thing Sheol has to a public square, this cavernous assembly hall hosts loyalty rallies, state-mandated “community festivals,” and tightly controlled grievance hearings.

Society & Culture

Life in Sheol is a struggle for stability, dignity, and a few fleeting comforts. The sector’s population is a mix of laborers, low-level clerks, food technicians, and their dependents. Most jobs are assigned by the Census Hall, and changing one’s station is nearly impossible.
The bureaucracy is omnipresent: every move, meal, and medical visit is logged and cross-checked by the Registry. Civil security officers patrol the corridors, but much of the real order is maintained by “block marshals”—appointed resident enforcers who balance quotas with keeping the peace.

Despite the hardships, Sheol’s people are resilient. Mutual aid societies, informal barter networks, and secret faith circles thrive in the shadows. Children are taught to revere Astraea’s order, but also to cherish small acts of rebellion—smuggled fruit, unregistered song circles, or a single, unauthorized flowerpot in a window.

On the rare festival day, the Community Forum is decked in faded banners and synthetic garlands while block choirs perform state-approved anthems. But the real celebrations take place in private, behind sealed doors and thick curtains.

Notable Locations

• Census Hall: Endless lines, forms, and official decrees.
• Rationworks: The sector’s green lungs and synthetic stomach.
• Greenlight Block: A rare oasis of hope, with rooftop gardens and a thriving barter market.
• The Gutter Zones: Refuge and danger for society’s forgotten.
• Registry: The digital ledger of every life in Sheol.
• Community Forum: The sector’s official voice and stage.

Current Climate

Sheol is at a breaking point. Ration shortfalls and overcrowding have led to rising tensions, especially in the lower blocks. A recent Registry corruption scandal triggered mass protests, quickly suppressed by civil security. Rumors of organized resistance and “gutter preachers” calling for reform circulate despite increased surveillance.
Administrators have responded with loyalty drives and ration bonuses for “model citizens,” but the mood remains sour. Even the block marshals are whispering that something must change—or break.

Notable Residents of Sheol

Director Helena Park
Sector Administrator. Known for her iron will and unbending devotion to quotas, Park is the face of Astraea’s bureaucracy in Sheol. She is both feared and respected for her ability to resolve crises—by any means necessary.

Chief Marshal Radoslav Petrov
Head of Civil Security. Petrov is a veteran enforcer whose patrols keep the peace in the Living Blocks. He is uncompromising, but secretly keeps a blacklist of residents he wants to protect from the system’s worst excesses.

Supervisor Marta Okafor
Rationworks Supervisor. Marta oversees hydroponics and food synthesis, juggling impossible demands and constant equipment failures. She runs a secret “gleaners’ network” smuggling extra food to the neediest families.

Registrar Wen Qian
Lead Analyst at the Registry. Wen is a data savant whose algorithms assign labor, rations, and medical care. Haunted by guilt over a past error that ruined a family, she is quietly helping others “disappear” from the system when the need is dire.

Marshal Ilya Stein
Block Marshal of Greenlight. Ilya is a beloved figure who organizes unofficial markets, barter circles, and clandestine garden clubs. His popularity makes him useful to the Directorate—and dangerous if he ever turns against it.

Preacher Jonah Kessler
Gutter Zone Faith Leader. Once a Census Hall clerk, Kessler now leads secret gatherings in the Gutter Zones, preaching hope and mutual aid. He is watched closely by security, but his following grows with every hardship.

Sheol’s people live in the shadow of the system, but their endurance, solidarity, and quiet acts of defiance are the seeds of a different future—one even Astraea’s bureaucracy may someday be forced to reckon with.

Overview:
Helheim (Sector 5) is the unforgiving heart of Erebus’s resource extraction empire—a vast, arid expanse where the richest Etherium veins are clawed from the bone-dry crust by a hardened workforce. Positioned in the southern interior, far from Erebus’s rare ice fields and vanishingly small open waters, Helheim is a place where dryness is a blessing and water is the most dangerous contaminant imaginable. Here, extraction is a science and a gamble, for even the smallest trace of moisture can trigger a catastrophic Etherium volatilization—an explosive loss of product, life, and machinery.

Geography & Location

Helheim sprawls across a region of ancient, rocky highlands and salt flats, its surface a patchwork of wind-scoured mesas, barren mineral fields, and sun-bleached extraction towers. The climate is brutally cold but—crucially—desiccated: the air itself is drier than any desert on Earth, and humidity is kept artificially low by sector-wide vapor scrubbing systems.

Below ground, Helheim’s labyrinthine mining tunnels and extraction chambers descend through strata rich in Etherium crystals. Every shaft and chamber is equipped with elaborate dehumidification technology, and entry protocols are strict: workers pass through airlocks, dust baths, and multiple dry-suit checks before stepping anywhere near the precious blue ore.

Major Facilities & Districts

• The Etherium Lodes:
  Massive, carefully mapped mining zones where raw Etherium is extracted by teams clad in moisture-sealed suits. Every tool, breath, and movement is monitored for stray vapor—one droplet could spell disaster.

• The Desiccatum Plant:
  The sector’s primary atmospheric control facility, responsible for maintaining ultra-dry conditions across all tunnels and processing sites. Climate engineers are among the most respected (and well-paid) workers in Helheim.

• The Refinery Vaults:
  Subterranean complexes where Etherium is stabilized and processed under hermetically sealed, water-free conditions. The air here is so dry it cracks skin and corrodes unshielded electronics.

• Scoria Station:
  The largest of Helheim’s worker settlements, built from insulated prefab modules and linked by covered, climate-controlled walkways. Life here is spartan, the only greenery found in sealed hydroponics labs strictly isolated from all mining activity.

• Dryline Command:
  The sector’s administrative and security hub, Dryline coordinates all extraction, transport, and enforcement operations. Here, Resource Marshals enforce safety with absolute authority and zero tolerance for negligence.

Society & Culture

Helheim’s people are as dry-witted as the air they breathe. The sector’s workforce consists of miners, climate engineers, resource marshals, safety inspectors, and their families—all bound by a culture of caution, discipline, and mutual dependence.
Safety is not just a protocol but a way of life. Workers undergo daily “dry drills,” checking suits and equipment for leaks, and are trained to treat even sweat as a potential hazard. Stories of water-related accidents—“blue flashes”—are cautionary legends, their victims memorialized in sector shrines.

Social life revolves around the mess halls and dry pubs of Scoria Station, where water is a strictly rationed industrial commodity and drinking is limited to carefully measured, sterilized rations. The rarest treat is a hot, dry sauna—moisture is the enemy, and humidity is a curse.
Children are raised on stories of vigilance and discipline, and many dream of becoming climate engineers or safety marshals—the “dry wardens” who keep everyone alive.

Despite the sector’s severity, camaraderie runs deep. When an accident does occur, rescue and containment crews mobilize instantly. The sector’s unofficial motto: “Not a drop, not a death.”

Notable Locations

• Desiccatum Plant: Where Helheim’s climate is engineered and maintained.
• Etherium Lode Alpha: The richest, most perilous vein in the sector—site of both fortunes and tragedies.
• Scoria Station Commons: The social and logistical heart of the worker community.
• Shrine of the Dry Watcher: A humble alcove where miners leave talismans and dry salt crystals for luck.

Current Climate

Helheim is currently on high alert after a rare vapor incursion triggered a blue flash that cost dozens of lives and millions in lost Etherium. Investigations and safety drills have redoubled, and morale is strained but unbroken. Rumors of sabotage and black market water smuggling circulate, but most dismiss them as old miners’ tales—until the next alarm sounds.

With quotas rising and safety margins shrinking, Helheim’s workers know they are the only line between prosperity and planetary disaster—one careless breath, one stray drop, and it all goes up in blue fire.

Notable Residents of Helheim

Chief Resource Marshal Oskar Tan
Sector commander responsible for safety and production. Tan’s zero-tolerance rule is legendary; his calm under pressure has saved hundreds, but his unforgiving nature makes enemies as easily as friends.

Climate Engineer Lead Mariana Holt
Head of the Desiccatum Plant, Holt is a problem-solver and innovator whose vigilance is the backbone of Helheim’s survival. She trains every new engineer herself and takes personal responsibility for every climate breach.

Foreman Pavel Saito
Supervisor of Etherium Lode Alpha. Saito is a veteran miner known for his encyclopedic knowledge of safety protocols and his ability to keep his crew alive in the most dangerous tunnels.

Safety Inspector Vera Singh
Chief of the Inspection Corps, Vera leads daily dry drills and investigates every incident. Her reports are feared for their candor and their consequences.

Quartermaster Anya Petrescu
Logistics chief at Scoria Station, Anya ensures that every suit, tool, and ration is accounted for and moisture-free. She is also a trusted counselor for homesick or anxious workers.

Medic Yoon-Seo Kim
Chief Medical Officer, Scoria Clinic. Kim manages everything from dehydration to industrial trauma and is often the first to spot the signs of stress or negligence that can lead to disaster.

In Helheim, vigilance is life, dryness is salvation, and every Etherium crystal pried from the earth is a victory over chaos—so long as no one lets down their guard.

Overview:
Avernus (Sector 6) is the ironclad fist of Erebus—the planet’s principal military and strategic command sector, where Astraea’s doctrine of control is forged into action. A labyrinth of fortified barracks, weapons foundries, training domes, and tactical command centers, Avernus is the domain where order is enforced by strength and security is maintained at any cost. Located in the storm-scarred eastern highlands, Avernus stands as the first and last line of defense against internal rebellion and external threats. Here, discipline is absolute, duty is demanded, and every citizen is reminded that the price of peace is eternal vigilance.

Geography & Location

Set atop a rocky plateau riddled with basalt outcroppings and natural choke points, Avernus is purpose-built for defense and rapid mobilization. Its surface is dominated by the imposing Citadel Bastion—a sprawling fortress complex surrounded by concentric rings of walls, automated turrets, and armored vehicle yards.
Below ground, the sector’s tunnels house weapons assembly lines, munitions depots, secure training facilities, and the planet’s chief strategic command bunker, all protected by reinforced blast doors and redundant security systems.

Avernus is connected to Agartha, Tartarus, and Niflheim by heavy-gauge maglev lines and military transit tunnels, allowing for swift troop movement and logistical resupply in an emergency.

Major Facilities & Districts

• Citadel Black:
  The nerve center of planetary defense and logistics, communications hubs, and secure quarters for senior officers. Its war room is constantly staffed, ready to respond to any crisis.

• The Parade Grounds:
  An immense, open training expanse where troops drill under the unblinking eyes of instructors and surveillance drones. Massed formations and live-fire exercises are daily routines.

• The Armory Complex:
  A fortified manufacturing and storage district where weapons, ammunition, and combat vehicles are produced, maintained, and distributed. Only authorized personnel are permitted entry.

• Warrior’s Row:
  Barracks and communal facilities for enlisted soldiers and officers. Spartan, orderly, and meticulously maintained, these living quarters reinforce the sector’s culture of discipline.

• The Tactical School:
  The premier academy for officer training, strategic planning, and advanced war games. Only the most promising recruits are admitted, and its alumni dominate Astraea’s security forces.

• Detention Block Delta:
  A high-security prison for captured rebels, suspected saboteurs, and traitorous officers. Interrogations and “loyalty rehabilitation” are routine here.

Society & Culture

Life in Avernus revolves around loyalty, hierarchy, and relentless readiness. The sector’s population is almost entirely military or support personnel—soldiers, officers, weapons engineers, and their families—bound by a strict code of conduct and a culture that prizes efficiency, sacrifice, and obedience.
Promotion is earned through unwavering discipline, successful missions, and the recommendation of superiors. Infractions, even minor, are punished swiftly, and public reprimands are common.
Patriotism is a daily ritual: the sector anthem is played at dawn and dusk, and loyalty oaths are renewed at every shift change.
Despite the severity, there is a strong esprit de corps. Camaraderie among units is fierce, and off-duty hours are spent in competitive sports, tactical games, or recounting battlefield exploits in the mess halls.
Children are raised in a culture of martial pride, many attending preparatory schools designed to funnel them into the ranks.

Notable Locations

• Citadel Black War Room: The beating heart of planetary defense and crisis response.
• The Parade Grounds: Where discipline is drilled and strength is displayed.
• Armory Alpha: The largest weapons depot in Erebus.
• Tactical School Arena: Site of legendary war games and officer graduations.
• Detention Block Delta: Where traitors are held—and sometimes disappear.

Current Climate

Tensions are high in Avernus. Recent intelligence leaks and sabotage incidents in Tartarus and Helheim have prompted sector-wide security reviews and emergency drills. The Supreme Command has issued new loyalty protocols, and Detention Block Delta is overcrowded with suspects.
Rumors of infiltration by resistance elements circulate, and troop morale is strained by long rotations and ever-increasing readiness demands.
Yet, the sector’s leaders insist that Avernus stands unbroken—ready to defend Astraea’s rule against all threats, from within or without.

In Avernus, every day is a battle against complacency, every citizen a soldier in Astraea’s war for survival. Here, the price of peace is paid in vigilance, sacrifice, and the unbreakable will to defend Erebus—no matter the cost.

Overview:
Mictlan (Sector 7) is the nerve center of Erebus’s biomedical innovation, genetic engineering, and biopolitical control—a labyrinth of research domes, sterile laboratories, biotech factories, and grim medical wards. Home to the infamous Vitatech Laboratories, Mictlan is where Astraea’s vision of a “perfected” population is pursued with relentless ambition and chilling detachment. The sector’s motto is “Progress Through Adaptation,” but for many, it is a place of whispered rumors, ethical nightmares, and a constant, low-level dread. Here, the line between healing, enhancement, and exploitation is perilously thin.

Geography & Location

Situated northeast of Agartha among a cluster of geothermally active mesas, Mictlan is deliberately isolated—shielded by toxic gas vents and seismic buffer zones. The sector’s gleaming bio-domes and stark, angular research towers rise from the barren rock, linked by sealed walkways and monorails.
Most facilities are built deep underground, protected from both sabotage and contamination. The air is filtered, the water recycled, and every visitor is rigorously scanned for pathogens, unauthorized genetic material, or even the “wrong” ancestry.

Major Facilities & Districts

• Vitatech Prime Complex:
  The central headquarters of Vitatech Laboratories—a sprawling, multi-level compound where the corporation’s top scientists, executive board, and biosecurity teams reside. Access is by genetic clearance only.

• The Genebanks:
  Cold storage vaults housing the DNA records, stem cell libraries, and “heritage archives” of Erebus. These are tightly guarded: the loss or sabotage of a single vault could cripple entire social classes.

• The Chimera Yards:
  Restricted bioreactor farms and testbed facilities where new lifeforms, servitor races, and experimental fleshwarps are designed, grown, and evaluated. Only authorized personnel are permitted, and rumors abound of secret, failed, or rogue creations.

• The Adaptation Clinics:
  Public-facing medical centers that offer genetic therapies, prosthetic upgrades, and preventative medicine to Erebus’s population—provided they are in good standing with Astraea’s social registry.

• Fleshforge Annex:
  A notorious sub-sector where radical procedures—fleshwarping, organ regrowth, eugenics editing—are conducted. Many of Erebus’s fleshwarps and engineered servitors began their existence here, willingly or otherwise.

• The Quarantine Wards:
  Biosecure isolation chambers for outbreaks, failed experiments, and the treatment of “biological irregularities.” Heavily patrolled and sealed from the rest of the sector.

Society & Culture

Mictlan’s population is a mix of Vitatech scientists and engineers, medical technocrats, security personnel, and a rotating cast of patients, test subjects, and fleshwarp laborers. The social hierarchy is strictly enforced by biometric ID, genetic “purity,” and compliance with the latest eugenics directives.
Innovation is prized but closely monitored; even minor protocol violations can result in demotion, reassignment to the Quarantine Wards, or disappearance.
For workers, the sector offers the best healthcare and longest life expectancy on Erebus—if you qualify. For everyone else, Mictlan is a place of anxiety, rumors, and the ever-present fear of being selected for “adaptation.”
Underground, an uneasy alliance of fleshwarps, failed experiments, and dissident med-techs have begun to form a secret mutual aid network, providing sanctuary and black-market gene therapy to those rejected by the system.

Notable Locations

• Vitatech Prime Boardroom: Where all major policies and research initiatives are set.
• Genebank Omega: The most secure DNA vault on the planet.
• Fleshforge Annex: The sector’s most infamous and secretive facility.
• Adaptation Clinic Sigma: The most advanced public medical center in Erebus, but also the most intrusive.
• The Hidden Cell: A rumored underground refuge for escaped test subjects and rogue scientists.

Current Climate

Mictlan is on edge after a series of mysterious “genetic failures” and an unauthorized data leak that exposed classified experiments to the public. Vitatech’s leadership has doubled security, restricted access to sensitive areas, and initiated a sector-wide audit of all personnel and projects.
At the same time, calls for more humane treatment of fleshwarps and a growing “bio-justice” movement among lower-level staff threaten to spark unrest.
The sector’s leadership remains outwardly confident—but in Mictlan, trust is always in short supply, and control is never absolute.

Notable Residents of Mictlan

Director of Research Dr. Min-Jae Hoshino
Supreme authority over all scientific projects and genetic policy. Hoshino’s intellect and ambition are matched only by her icy pragmatism; she is both revered and feared among her peers.

Chief Medical Officer Dr. Eliza Grunwald

Security Chief Viktor Reznik
Responsible for all sector biosecurity, Reznik is relentless in rooting out breaches, leaks, and unauthorized experimentation. His interrogations are swift, his tolerance for failure nil.

Lead Bioengineer Talia Singh
Supervisor of the Chimera Yards. Talia is known for her creative designs and her secret sympathy for failed experiments and fleshwarps. She is suspected of covertly helping some escape “retirement.”

Registrar Iván Mendoza
Manager of the Genebanks. Mendoza’s organizational skills are unmatched, and his knowledge of genetic lineages makes him one of the most powerful “gatekeepers” in Erebus society.

Fleshwarp Advocate “Patch”
A heavily modified survivor of the Fleshforge Annex, Patch (real name unknown) has become an underground leader for fleshwarp rights. Rumors place them at the heart of the sector’s growing dissident network.

In Mictlan, every cure is a potential weapon, every improvement another step toward control—or rebellion. Here, the future of Erebus is written in genes, and the line between salvation and suffering is as thin as a strand of DNA.

Overview:
Shambhala (Sector 8) is the rarefied apex of Erebus society—a gilded enclave of privilege, power, and insulated luxury rising above the planet’s unyielding hardship. Reserved for Astraea Corporation’s senior executives, scientific luminaries, political strategists, and their families, Shambhala is simultaneously a fortress, a playground, and a golden cage. Here, the air is filtered, the water pure, and every need is met by an army of discrete servitors and cutting-edge automation. But beneath the sector’s tranquil surface, old rivalries, corporate intrigue, and the gnawing dread of downfall are never far away.

Geography & Location

Located atop an isolated mesa at the planet’s temperate equatorial belt, Shambhala commands sweeping views of the volcanic lowlands and the distant icy horizon. Designed as a “city above the fray,” its architecture is a striking blend of hypermodern towers, sky bridges, and crystalline domes.
The sector is physically and socially walled off from the rest of Erebus: entry is by biometric clearance only, and maglev lines terminate at security-controlled gates.
Much of Shambhala’s infrastructure is subterranean, including climate-controlled gardens, private spas, entertainment halls, secure data vaults, and the sector’s own emergency bunker.

Major Facilities & Districts

• Executive Plaza:
  The heart of Shambhala, where Astraea’s top decision-makers work and socialize. Here stand the company’s Grand Strategy Hall, the Market of Ideas, and the Spire of Innovation.

• The Crystal Gardens:
  Vast, climate-controlled biomes filled with rare and exotic flora from both Erebus and Elysium. These gardens serve as status symbols, networking venues, and sites for discreet negotiation.

• Residential Towers:
  Luxurious, multi-level homes for the senior echelon. Each tower is a private kingdom, boasting advanced security, personal attendants, and panoramic views.

• Skybridge Commons:
  An elevated promenade connecting key towers and plazas, lined with boutiques, art galleries, and gourmet restaurants. Here, the elite display their wealth and compete for influence.

• The Vault:
  A fortified data and resource center where the sector’s most sensitive information, valuables, and contingency supplies are stored.

• Service Quarters:
  Hidden beneath the surface, this area houses maintenance staff, servitors (including many fleshwarps and loyal dwarves), and automated logistics hubs. Human contact between staff and executives is strictly regulated.

Society & Culture

Life in Shambhala is defined by opulence, competition, and underlying paranoia. Residents enjoy privileges unimaginable elsewhere on Erebus: unrestricted food, real sunlight in the gardens, personal medical teams, unrestricted access to unfiltered information, and even simulated “natural” weather.
Status is everything—each resident’s standing is measured by influence, innovation, and the favor of Astraea’s uppermost Directorate. Alliances are fluid, and social maneuvering is an art form.
Children are raised in isolation from the lower sectors, tutored by the best minds and conditioned for leadership.
Despite the comforts, the sector is rife with anxiety. The possibility of scandal, demotion, or exile to a lower sector is ever-present, and the fear of “falling” shapes every interaction.
Rumors of secret societies, forbidden entertainments, and plots against rivals circulate in the lounges and private suites.

Notable Locations

• Grand Strategy Hall: The nerve center for Astraea’s planetary planning and elite gatherings.
• The Crystal Gardens: Lush, climate-controlled spaces for relaxation and backroom deals.
• Innovation Spire: Where breakthrough technologies and policies are unveiled—or sabotaged.
• The Vault: The sector’s most secure and secretive facility.
• Skybridge Commons: The public face of Shambhala’s wealth and taste.

Current Climate

Shambhala is simmering beneath its polished surface. A recent scandal involving leaked data from the Vault has triggered a wave of internal audits, and several families are rumored to be under covert investigation.
Competition for the next Directorate seat is fierce, and old alliances are fracturing. Meanwhile, a series of unexplained “malfunctions” in the Service Quarters has led to whispers of sabotage.
Despite increased security and an official air of calm, many residents are quietly preparing escape plans—or blackmail dossiers—should the winds of fortune shift.

Director of Youth Development Dr. Mira Vogel
Oversees the education and psychological conditioning of Shambhala’s children. Mira is respected for her results and feared for her unorthodox methods.

In Shambhala, luxury is a right, status is a weapon, and every comfort comes with a price. Here, the air is sweet, the walls are thick, and the eyes of Astraea watch every move—ensuring that the heights of privilege are never truly safe.

Overview:
Duat (Sector 9) is the neural nexus of Erebus—the sector where information is power, secrets are currency, and surveillance is an art form. Here, the streams of planetary communication, propaganda, and data converge, processed in vast analog datacenters and relayed across Erebus’s labyrinthine infrastructure. Duat is home to the Directorate’s Ministry of Information, the Bureau of Records, and the infamous Censorium. It is a place of flickering screens, pneumatic tubes, and endless filing cabinets, where the line between truth and fiction is deliberately blurred and every citizen is a potential subject of observation.

Geography & Location

Situated near the northern pole, Duat occupies a sprawling warren of reinforced bunkers and transmission towers built into the permafrost and crystalline salt flats. Above ground, the sector is crowned by the Obelisk Array—a forest of steel radio masts, dish antennas, and searchlights that pulse day and night with coded messages and propaganda broadcasts.

Below, Duat’s heart is a honeycomb of archives, print rooms, and analog computation halls. Pneumatic tubes connect offices and databanks, while secure maglev lines shuttle couriers and officials to Agartha, Niflheim, and other key sectors.

Major Facilities & Districts

• Ministry of Information Complex:
  The administrative and command center for all official communication, media, and propaganda. Here, the day’s news, public orders, and loyalty bulletins are written, reviewed, and distributed.

• The Censorium:
  A high-security facility where all media—print, sound, and film—is inspected, edited, and approved. Teams of censors work around the clock, redacting forbidden knowledge and inserting approved narratives.

• The Bureau of Records:
  An immense subterranean archive containing personal files, surveillance logs, and historic records on every citizen, sector, and event. Most data is stored on paper, microfiche, or punched cards, and is cross-indexed by a small army of clerks.

• The Obelisk Array:
  The sector’s iconic broadcast and relay station, sending signals to every corner of Erebus. It is also the first line of defense against off-world or rebel transmissions.

• Analogue Computation Halls:
  Vast rooms housing mechanical tabulators, punchcard computers, and early signal-processing equipment. These halls are the brains of planetary surveillance and are staffed by technicians and “calculators.”

• Courier Exchange:
  A secure, bustling hub where official messengers deliver sealed packets, microfilms, and encoded reels to and from other sectors.

Society & Culture

Duat’s population is drawn from the ranks of bureaucrats, editors, censors, record-keepers, technicians, and couriers. Promotion is based on discretion, loyalty, and one’s ability to read between the lines.
Life in Duat is regimented and secretive. Employees are required to sign daily loyalty oaths and submit to random “thought audits” and background checks.
Gossip is both a danger and a survival skill; even a careless word can lead to reassignment or questioning by Internal Affairs.
Despite the paranoia, there is subtle camaraderie among the workers. Jokes about “the all-seeing eye” and “the ghost in the tubes” are common, and some quietly subvert the system by hiding forbidden books or communicating in coded language.
Art, music, and literature are tightly regulated, but a clandestine culture of samizdat—hand-copied, underground works—flourishes in hidden corners.

Notable Locations

• Ministry of Information Auditorium: Where new directives, propaganda campaigns, and “historical updates” are unveiled to select audiences.
• The Censorium Review Chamber: Infamous for its “red-ink nights,” when entire broadcasts or novels are erased.
• The Bureau’s Deep Vault: Where the most sensitive secrets, blackmail files, and erased identities are locked away.
• Obelisk Control Tower: The highest and coldest point in Duat, where signalmen monitor for unauthorized transmissions.
• Courier Exchange Platform: Where loyal messengers race against time, weather, and prying eyes.

Current Climate

Duat is on heightened alert after a string of data leaks and intercepted rebel broadcasts. Security sweeps are frequent, and several high-ranking censors have vanished under mysterious circumstances.
The Ministry of Information has ordered a sector-wide review of all records and increased the pace of loyalty campaigns.
Rumors swirl of a “phantom operator” using obsolete broadcast equipment to send subversive messages to the lower sectors, and paranoia is at an all-time high among both workers and leaders.

Notable Residents of Duat

Minister of Information Helena Voss
Head of the sector and chief architect of Astraea’s information policy. Voss is known for her cold precision, photographic memory, and ability to predict public reaction before it happens.

Chief Censor Emiliano Duarte
Leads the Censorium’s review teams. Duarte is feared for his thoroughness and his creative use of “historical revision.” He is rumored to keep a secret archive of unaltered works.

Director of Records Wenjie Song
Oversees the Bureau of Records and all personal files. Song’s encyclopedic knowledge of Erebus’s citizens makes her a powerful, if discreet, figure.

Signalmaster Viktor Rau
Commands the Obelisk Array and all broadcast operations. Rau is obsessive about signal integrity and is haunted by a past signal breach that nearly brought disaster.

Senior Courier Petra Ivanova
The fastest and most trusted messenger in Duat. Ivanova is famous for her discretion, but also for her encrypted side business delivering “unofficial” messages to select clients.

Analogue Technician Reza Farzan
Maintains the sector’s aging computation halls. Farzan is a quiet innovator who sometimes covers for rebellious coworkers or subtly sabotages “malicious” surveillance programs.

In Duat, the walls have ears, the records never die, and the only thing more dangerous than a secret is the truth. Here, the Directorate’s control is absolute—unless, of course, you know the right code, the right person, or the right moment to disappear.

Overview:
Hephaestus (Sector 10) is the battered heart of Erebus’s industrial maintenance and technological salvage—a sprawling district of smoke-stained factories, machine shops, and cavernous repair depots where the relics of a lost golden age are nursed along by ingenuity and desperation. Located in the industrial basin east of Tartarus, Hephaestus is where the battered machinery that keeps Erebus alive—maglev engines, atmospheric scrubbers, ancient automata, and even failing cybernetic prosthetics—are repaired, repurposed, or cannibalized for spare parts. Here, the clang of hammers and the whirr of gears never cease, and the line between “maintenance” and “miracle” is often vanishingly thin.

Geography & Location

Hephaestus sprawls across a labyrinth of reinforced concrete and steel superstructures built atop the foundations of pre-Event factories and repair yards. Above ground, the sector is a forest of smokestacks, monorail gantries, and massive loading cranes.
Below, a network of maintenance tunnels, storage vaults, and machine halls connects the sector’s primary facilities. The air is thick with the scent of oil, ozone, and burnt insulation—a constant reminder of the sector’s ceaseless struggle against entropy.
Hephaestus is linked by freight maglev and conveyor lines to Tartarus, Agartha, and Shambhala, making it a logistical hub for the movement of both essential goods and salvaged tech.

Major Facilities & Districts

• The Central Machineworks:
  The largest assembly and repair hall in Erebus, where everything from maglev locomotives to air filtration turbines are disassembled, refurbished, or rebuilt from scratch. Its “Miracle Bay” is famous for last-ditch salvage jobs.

• The Relic Yards:
  Acres of fenced lots and open-air warehouses where ancient, high-tech machines and automata are stored, awaiting repair or repurposing. Some relics date back to the original colonial landing and are operated by only a handful of trusted engineers.

• The Foundry Blocks:
  Rows of blast furnaces, metal presses, and tool-and-die workshops supporting the sector’s repair efforts. Much of the equipment is nearly a century old, kept functional by endless patching and improvisation.

• The Tinker’s Quarter:
  A bustling enclave of independent machinists, inventors, and black-market fixers. Here, forbidden modifications and unauthorized repairs are exchanged in back-room deals, often in defiance of Astraea’s regulations.

• Control Operations Center:
  The nerve center for sector logistics and emergency response, coordinating maintenance tasks, power grid management, and the allocation of skilled labor.

• Warden’s Hall:
  The administrative headquarters, home to the sector’s management, labor coordinators, and the all-important “parts registry.”

Society & Culture

Hephaestus is defined by its relentless work ethic, problem-solving spirit, and grim camaraderie. The sector’s population is a mix of machinists, repair crews, veteran engineers, labor drafts from Tartarus, and a handful of aging “Tech Keepers” entrusted with ancient systems.
Promotion is based on skill, creativity, and the ability to keep the impossible running for one more day. Apprenticeship is the path to advancement, with knowledge passed down through generations of trial and error.
There is a deep, almost religious reverence for high-tech relics—some crews offer prayers to forgotten engineers and leave offerings at the oldest machines.
Despite Astraea’s strict regulations, an undercurrent of independence and innovation persists. The Tinker’s Quarter, in particular, is a hotbed of resistance, with machinists secretly collaborating with dissidents to repurpose relics for non-sanctioned purposes.

Festivals are rare, but when a major repair is completed or a “lost” machine is revived, spontaneous celebrations break out, with music from jury-rigged radios and homemade spirits shared among crews.

Notable Locations

• Miracle Bay (Central Machineworks): The last stop for dying machines and desperate engineers.
• Relic 17: The sector’s most legendary automaton, still functional after 300 years—barely.
• The Tinker’s Quarter: Where the rules are bent and innovation thrives.
• Warden’s Hall: The administrative heart, where every part and every worker is tracked.
• The Old Dynamo: A pre-Event generator that powers a third of the sector and is tended like a sacred artifact.

Current Climate

Hephaestus is under immense pressure. A recent surge in breakdowns—some suspected to be sabotage—has stretched resources to the limit. Spare parts for the most vital high-tech relics are almost gone, and some systems are kept running by cannibalizing others. Astraea has sent auditors and security teams to crack down on black-market repairs and “misuse” of relics, leading to mounting tensions with the machinist guilds and the Tinker’s Quarter.
Rumors swirl of a secret effort to build a new automaton from salvaged parts—a project that could change the balance of power in the sector, or doom it if discovered.

Notable Residents of Hephaestus

Chief Maintenance Officer Jiro Watanabe
The sector’s top engineer and de facto leader, Watanabe is a legend for his ability to coax life out of dead machinery. Gruff, tireless, and fiercely protective of his team, he is both respected and feared.

Lead Tech Keeper Magdalena Vasquez
Guardian of the oldest high-tech relics, Vasquez is a living encyclopedia of lost procedures. She is revered by apprentices and resented by Astraea’s auditors for her “creative” record-keeping.

Logistics Coordinator Pavel Ionov
Responsible for the allocation of parts, labor, and repair schedules. Ionov is a master of negotiation and a lynchpin in the sector’s delicate balance between order and chaos.

Security Director Tomasz Blanchard
Head of the sector’s security and compliance teams. Blanchard is tasked with rooting out sabotage and unauthorized repairs, but privately admires the ingenuity of the Tinker’s Quarter.

Master Tinker “Sprocket”
A legendary figure in the Tinker’s Quarter, Sprocket (real name unknown) runs the black-market repair network. A folk hero to machinists, Sprocket is always one step ahead of Astraea’s enforcers.

Apprentice Engineer Lian Yao
A rising star whose innovative modifications have saved more than one critical system. Lian is watched closely by both Watanabe and the security office.

In Hephaestus, every clang of the hammer is a prayer against failure, and every spark from a relic’s core is a reminder that Erebus survives not by perfection—but by the stubborn refusal to let the past die.

Overview:
Xibalba (Sector 11) is the grim underbelly of Erebus—a sprawling penal-industrial sector where Astraea Corp exiles its undesirables, dissidents, criminals, and failed experiments. Named after the underworld of Mayan myth, Xibalba is both a prison and a labor camp: its population is forced to toil in hazardous mines, waste processing plants, and recycling yards, fueling the rest of the planet’s machinery with their sweat and, often, their lives. The sector is infamous for its brutality, overcrowding, and the ever-present threat of “disappearance.” Yet, in its darkest corners, hope, resistance, and fierce camaraderie persist.

Geography & Location

Carved into a series of winding canyons and deep sinkholes in Erebus’s western badlands, Xibalba is isolated from the rest of the planet by both natural barriers and militarized checkpoints.
Above ground, razor-wire fences and watchtowers ring the sector’s perimeter. Guard barracks, processing centers, and security vehicle depots form a fortified shell around the sprawling penal complex.
Below, a labyrinth of cell blocks, forced-labor mines, waste reclamation pits, and “re-education” facilities honeycomb the rock. Smog-choked air, constant klaxons, and the ever-present rumble of machinery mark daily life.

Major Facilities & Districts

• Central Processing Compound:
  The administrative hub for incoming prisoners, discipline boards, and labor assignments. All new arrivals are catalogued, stripped of belongings, and assigned to work details.

• The Pit Mines:
  Open-cast and tunnel mines where prisoners extract low-grade ore, toxic minerals, and salvageable detritus from collapsed relics. Accidents, cave-ins, and sabotage are routine.

• The Reclamation Yards:
  Gigantic sorting fields and incinerators where inmates process hazardous waste, scrap metal, and industrial byproducts. Many suffer injuries or chemical burns in the line of duty.

• Cell Block Delta:
  The largest residential block, notorious for overcrowding, gang violence, and unsanctioned trade. “Block bosses” maintain a fragile order, often in uneasy partnership with the guards.

• The Isolation Vaults:
  High-security cells for political prisoners, suspected resistance members, and failed Vitatech fleshwarps. Few return from prolonged isolation unchanged.

• The Chapel of Lost Names:
  A secret shrine where prisoners inscribe the names of the disappeared and hold quiet memorials. It is a focal point for hope and underground resistance.

Society & Culture

Xibalba’s society is a desperate mix of hardened criminals, political prisoners, fleshwarps, outcast dwarves, and those simply unlucky enough to offend Astraea’s regime.
Life is governed by a harsh code of survival: strength, cunning, and alliances with fellow inmates or even corrupt guards can mean the difference between life and death.
Smuggling, black market trading, secret religious gatherings, and coded graffiti are common means of resistance.
Prison gangs and “block bosses” exert local control, collecting tribute and enforcing rules—sometimes more fairly than the official authorities.
Despite the suffering, fierce bonds of solidarity can form. Prisoners share medical supplies, information, and even small comforts in defiance of the system.

Punishments are severe: infractions can mean a stint in the Isolation Vaults, assignment to the most dangerous work crews, or summary “disappearance.”
Occasionally, rumors circulate of successful escapes, hidden tunnels, or sympathetic guards—but these are as often a trap as a reality.

Notable Locations

• Discipline Board Chamber: Where sentences and punishments are handed down.
• The Pit Mines: The sector’s most dangerous and punishing labor zone.
• Cell Block Delta: The chaotic, violent heart of prisoner life.
• The Chapel of Lost Names: A candle-lit alcove of memory and quiet rebellion.
• Isolation Vault 7: Site of the most feared solitary confinement cells.

Current Climate

Xibalba is on the verge of open revolt. Increased “disappearances,” a rash of accidents in the Pit Mines, and rumors of a new resistance network have led to brutal crackdowns.
Guards are stretched thin, morale is low, and the block bosses are negotiating an uneasy truce to focus on survival.
A recent transfer of high-profile political prisoners has ignited hope—and anxiety—that a breakout or mass protest could be imminent.
Meanwhile, Astraea’s Directorate debates whether to send in reinforcements, or simply seal and abandon the most troublesome blocks.

Notable Residents of Xibalba

Warden Emilia Rojas
Sector commander, responsible for all security and administration. Known for her ruthless discipline and “no second chances” policy, Rojas is both feared and despised by staff and inmates alike.

Labor Overseer Doruk Kaya
Manages forced labor assignments and quotas; infamous for his callous disregard for prisoner safety. Kaya is rumored to run a lucrative black market in work assignments and contraband.

Chief Psychologist Dr. Lena Vostrikov
Leads the “re-education” program and mental health evaluations. Vostrikov’s therapies are a mix of genuine care and brutal brainwashing, making her both a confidante and a threat to inmates.

Block Boss “Cutter” Han
Unofficial leader of Cell Block Delta, Han keeps order through a mixture of violence and protection rackets. He is feared, respected, and sometimes sought out for mediation or illicit favors.

Resistance Liaison Mira Salvi
A former journalist imprisoned for subversive activity, Mira now acts as a secret courier and organizer for the underground resistance. Her coded messages and network of contacts keep hope alive.

Quartermaster Yevgeny Markov
Head of supply distribution for both staff and inmates, Yevgeny is a pragmatic survivor who can procure nearly anything—for a price. He walks a careful line between aiding prisoners and appeasing the guards.

In Xibalba, hope is measured in stolen moments, loyalty is forged in hardship, and every day is a struggle to survive—or to spark the rebellion that might, one day, bring down the walls

Overview:
Pluto (Sector 12) is the farthest, most forbidding reach of Erebus’s industrial machine—a sector synonymous with danger, desperation, and relentless extraction. Nicknamed “the Deep Dark,” Pluto is the planet’s primary deep-drilling and hazardous materials processing zone. Its workers face some of the harshest conditions on Erebus, contending with toxic gases, unstable geology, and the constant threat of catastrophic industrial accidents. Pluto is where Astraea’s appetite for rare elements and volatile compounds is fed, and where the cost of progress is measured in scars and silence.

Geography & Location

Situated in Erebus’s southern outback, Pluto’s terrain is a wasteland of jagged rock, salt flats, and ancient volcanic scars. The surface is pitted with drilling towers, containment domes, and sprawling slag heaps.
Beneath, a vast network of deep-core shafts and processing tunnels burrows miles into the crust—so deep that geothermal heat and pressure warp both metal and mind. Temperatures swing from lethal cold at the surface to stifling heat below, and the air is forever tinged with the scent of ozone, caustic chemicals, and burning insulation.

Pluto’s isolation is legendary: only a single maglev line connects it to Helheim and Agartha, and its roads are regularly swept by toxic dust storms.

Major Facilities & Districts

• The Drillfields:
  Expansive open pits and derrick clusters where massive rigs bore deep into the crust in search of rare minerals, volatile gases, and geothermal energy. Drillfields are surrounded by emergency shelters and automated hazard beacons.

• The Smogworks:
  Pluto’s central processing plant for refining hazardous materials, neutralizing toxins, and compressing volatile gases. Here, workers don heavy protective suits and shifts are kept short to minimize exposure.

• The Overflow Yards:
  Mountains of slag, chemical waste, and rejected ore dominate this district. Runoff and spills are a constant threat, and scavenger crews risk their lives extracting salvageable metals and machine parts.

• Chasm Station:
  The sector’s main worker settlement, perched on the rim of Pluto’s deepest extraction pit. Chasm Station is built for resilience: reinforced bunkers, pressurized living quarters, and a sealed marketplace keep the elements at bay.

• Geothermal Control Annex:
  An underground nerve center monitoring the network of heat exchangers, coolant lines, and pressure valves that keep Pluto’s mining operations from boiling over or freezing solid.

• Emergency Response Depot:
  A heavily fortified base for disaster response teams, medics, and environmental engineers. The Depot is always on high alert, as explosions, cave-ins, and gas leaks are part of daily life.

Society & Culture

Pluto’s society is forged by hardship and necessity. The sector’s population is a rough mix of seasoned deep-drill crews, chemical engineers, hazard response specialists, and the desperate—those who have nowhere else to go, or have been assigned here as punishment.
Hierarchy is simple: skill, courage, and reliability command respect. Those who crack under pressure or shirk their duties don’t last long.
Life revolves around the shift bell—everyone is either working, recovering, or training for the next emergency. There’s little patience for bureaucracy, and a strong tradition of looking after one’s crew.
Celebrations are rare, but when a major milestone is reached—a new record depth, averted disaster, or the rescue of a trapped team—the whole sector comes together in raucous, cathartic revelry.

The risk of contamination and disaster is always present. Many workers display ritual “luck charms” or tattoos, and tales of “the Echoes” (phantom voices heard deep underground) are common in the bunkhouses.

Notable Locations

• Drillfield Omega: The deepest and most productive drilling site in the sector, but also the most unstable.
• Smogworks Main Stack: The towering chimney where processed gases are vented—said to glow blue during storms.
• Chasm Station Market: The beating heart of Pluto’s social life, where deals, gossip, and dreams are traded.
• Geothermal Control Room 7: Site of the infamous “Steam Burst Incident,” now a safety shrine.
• The Memorial Wall: A steel-plated mural in Chasm Station listing the names of those lost to the Deep Dark.

Current Climate

Pluto is reeling from a recent string of disasters: a drilling collapse that swallowed an entire crew, a chemical fire that shut down a third of the Smogworks, and a mysterious surge in underground “Echo” phenomena that has spooked even the veteran teams.
Morale is brittle, with some workers demanding better equipment and others simply pushing through the pain.
Astraea has dispatched a new wave of supervisors and hazard auditors, but many old hands view them with suspicion—outsiders rarely last long in Pluto’s unforgiving depths.

There are rumors that an unprecedented mineral find lies beneath Drillfield Omega, but reaching it may push the sector’s aging machinery—and its people—past the breaking point.

Notable Residents of Pluto

Chief Drilling Engineer Valeria Petrov
Sector lead for all drilling operations, Valeria is renowned for her iron nerves and encyclopedic knowledge of deep-earth hazards. Her word is law on the Drillfields.

Geothermal Systems Director Tomasz Novak
Mastermind behind the sector’s fragile heat and pressure management. Tomasz is obsessed with preventing a catastrophic blowout, and is rumored to sleep in the Control Annex.

Market Warden “Mags” Duval
Unofficial boss of Chasm Station Market. Mags runs the social and supply network with a sharp eye and a generous hand for those in need—if they play by her rules.

Crew Chief Riley Mbaye
A respected shift leader on Drillfield Omega, Riley is famous for going into danger first and coming out last. His loyalty to his crew is unmatched.

Medic Supervisor Jun Park
Head of Pluto’s medical corps, Jun is a relentless advocate for worker health, and is often at odds with Astraea’s cost-cutting officials.

In Pluto, every shift is a wager against the Deep Dark, every scar is a badge of survival, and every name on the Memorial Wall is a reminder: Erebus’s wealth is won by those who dare the depths—and pay the price.

Sector 13 – Gehenna

Overview:
Gehenna (Sector 13) is a scar across the memory of Erebus—a once-thriving residential and industrial sector, now sealed, silent, and shunned. Lost in the chaos following The Event, Gehenna became ground zero for the most violent and uncontrolled riots in Erebus’s history. What began as desperate protests for food, medicine, and answers exploded into days of bloodshed, sabotage, and fire. When Astraea’s security forces finally retook the perimeter, they found only ruins, collapsed tunnels, and toxic smoke.

Geography & Location

Gehenna is located southwest of Sheol, occupying a series of deep, interconnected caverns and surface shantytowns.
Much of the sector is now a collapsed ruin—its upper levels caved in by explosions, its lower tunnels flooded with noxious gases and rubble. The entrances are permanently sealed by reinforced bulkheads, and the entire area is designated a “no-man’s land.”

Haunting Legacy

• The Ash Fields:
  The former industrial heart, now a wasteland of scorched machinery and collapsed smokestacks. It is rumored that vengeful spirits and mutated scavengers haunt the ruins.

• The Sunken Plaza:
  Once the sector’s social hub, now a blackened pit where survivors of the riots made their last stand.

• Block 17 Memorial:
  A forbidden shrine at the sector’s edge, covered in graffiti and wilted flowers, where families remember the lost.

Current Status

No one is officially permitted entry. Rumors persist of secret expeditions to salvage lost tech, and of survivors who never left, building a feral society in the darkness. Security drones patrol the perimeter, and any unauthorized approach is met with lethal force.

Sector 14 – Cocytus

Overview:
Cocytus (Sector 14) is a monument to sabotage—a sector whose destruction was both sudden and deliberate. Once Erebus’s chief communications and transport hub, Cocytus was obliterated in a coordinated terrorist attack by the Long Insurgence, who sought to sever Astraea’s logistical arteries and inspire revolt. Detonated charges, EMP blasts, and the unleashing of toxic agents crippled the sector in a single night, killing thousands and plunging the area into chaos.

Geography & Location

Situated northeast of Agartha, Cocytus was built around a complex of maglev stations, data centers, and underground hangars.
Now, its tunnels are twisted and warped, its infrastructure fused by fire and electromagnetic surges. The sector is a labyrinth of collapsed passageways, irradiated vaults, and shattered vehicles.

Haunting Legacy

• The Broken Spire:
  The collapsed comms tower at the sector’s heart—a gutted shell that still emits haunting, static-laced transmissions.

• Maglev Graveyard:
  Miles of derailed train cars and scorched tracks, now home to scavenger gangs and hostile automata.

• The Insurgent’s Mark:
  A defaced mural on the old transit terminal, believed to be the signature of the saboteurs.

Current Status

Cocytus is a forbidden zone. Hazard teams occasionally enter to recover vital tech or evidence, but most never return. The sector is rumored to be laced with booby traps and lingers under heavy surveillance for any sign of renewed insurrection.

Sector 15 – Pandemonium

Overview:
Pandemonium (Sector 15) is an enduring warning—a sector annihilated in a single, apocalyptic instant by a catastrophic blue flash Etherium explosion. Once a bustling mining and research district, Pandemonium held one of Erebus’s richest Etherium lodes. A containment failure—possibly sabotage, possibly negligence—allowed moisture to penetrate the main extraction shaft. The resulting chain reaction vaporized much of the sector, leaving only a radioactive crater and a legacy of loss.

Geography & Location

Pandemonium lies to the far south, its surface now an ashen crater ringed by warped, glassy rock and twisted machinery.
The sub-levels are either collapsed or flooded with residual Etherium gas and radiation. The air is unbreathable, and warning lights still flicker in the ruins.

Haunting Legacy

• The Blue Scar:
  The epicenter of the explosion, where the rock itself glows faintly at night. No living thing survives here.

• The Silent Shafts:
  Collapsed mining tunnels, their entrances sealed with blast doors and hazard markers.

• Memorial Wall 15:
  At the last checkpoint before the exclusion zone, a steel wall bears the names of every worker lost to the blue flash.

Current Status

Pandemonium is off-limits even to Astraea’s best-equipped salvage teams. Automated warning systems, radiation sensors, and lethal drones enforce the quarantine. Some say that the echoes of the explosion still reverberate through the earth, and that strange lights can be seen flickering in the depths.

The Legacy of the Lost Sectors

The stories of Gehenna, Cocytus, and Pandemonium cast long shadows over Erebus society. Their ruins are lessons in the price of chaos, sabotage, and carelessness—and reminders that in Erebus, the past is never truly buried.
For some, the lost sectors are forbidden ground; for others, they are a challenge, a source of legend, and perhaps even the last hope for those desperate enough to risk everything for what lies within.
