Trenchcrown (Abyssocorona geba)

Alias: None
Origin: Geban Sea (trenches)

The Trenchcrown is a crown-shaped coral species anchored in the dark depths of the Geban Sea’s trenches. Thriving in extreme cold and pressure, it forms rigid, layered crowns that shelter a wide array of deep-sea fauna. Its rare growth patterns make it a cornerstone of trench ecosystems and a cultural emblem of unfathomable depth.

Terrain

Deep trenches, anchored in cold, dark waters. Absent in shallow or inland biomes.

Lifespan

Lives 100–150 years. Matures at 15–20 years. Produces polyps during stable current cycles.

Height & Spread

Reaches 1–2 meters in height, spreading 1–3 meters. Juveniles grow between 0.3–0.8 meters.

Uses

Notes

Documented in the Era of Absolute Expansion (~3,000 years before modern Geba), Trenchcrowns remain vital to Geban Sea trench ecosystems. Extant and mysterious.
