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.

Lifespan

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

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.
