Selene: Moon of Elysium

Overview

Selene is the sole natural satellite of Elysium, gracing the planet’s night skies with its serene, pearly glow. Named for the ancient lunar goddess, Selene is a source of myth, poetry, and scientific fascination; a familiar companion to every inhabitant of Elysium, from city-dwellers to wilderness rangers.

Scientific Facts

  • Diameter: 2,950 km (about 85% the size of Earth’s moon)
  • Orbital Period: 29.7 Elysian days (nearly a perfect “month,” and the foundation of most Elysian calendars)
  • Distance from Elysium: 340,000 km
    (About 11% closer than Earth’s moon, which is 384,000 km away; Selene appears noticeably larger in the sky.)
  • Gravity: 0.13g (slightly lower than Earth’s moon)
  • Surface Features:
    • The Veil: A prominent, pale impact basin visible from Elysium as a silvery “scar.”
    • Luminous Highlands: Bright, rugged regions reflecting sunlight and giving Selene its signature glow.
  • Atmosphere: None (airless, with sharp temperature extremes)
  • Tidal Influence:
    Selene’s proximity makes Elysium’s tides slightly higher and more regular than Earth’s, but still within a safe, natural range. Coastal ecosystems are vibrant, and the tides are reliable enough for fishing and navigation traditions.
  • Astronomical Events:
    • Selenic Eclipse: Once each Elysian year, Selene passes between Elysium and the sun, casting a dramatic shadow.
    • The Silver Path: On nights of full Selene, her light is powerful enough to cast crisp shadows and is said to reveal “hidden truths,” a favorite motif in local legends.

Cultural and Mythic Significance

  • Symbolism: Selene is tied to dreams, intuition, tides, and time. She’s revered as a goddess, a guardian, and a silent judge.
  • Festivals: Full Selene nights are celebrated with city festivals and rural rituals; wishes made under her light are said to be especially powerful.
  • Folklore: Sailors, Catfolk, and Leshies tell tales of Selene’s “silver bridge” guiding the lost, and some druids claim to hear her voice in the tides and winds.

In-World Use

Selene’s phases are the basis for timekeeping, navigation, and many traditions across Elysium. Her bright and prominent presence is a nightly reminder of wonder, mystery, and Elysium’s place in the wider universe.
