Biome
Sunken Axum architecture wrapped in coral, with mid-depth power-plant chambers and root-canyon caves.
Sub-regions
The Overgrown Ruins are the bones of an ancient Axum settlement that the Protean sea has reclaimed. The biome sits at moderate depths, surrounded by power-plant remnants and observatory islands that double as story-goal hubs.
Root Canyons cut through the biome floor and connect to deeper currents. Most of the early Hoverthorn-class fauna lives here, alongside the more aggressive Bullethead and Pneuma populations that ambush from the canopy of coral overhangs.
A common early-Tadpole biome: shallow enough to dive without a depth module yet rich enough in scrap and surface crates to bootstrap a base.
Sorted by how often they spawn in this biome. Numbers are the count of placement points; higher means you'll meet one within a minute of swimming.

Coral Gardens
The bright, biodiverse Shallows-tier biome. Highest creature variety in the build and the heartland of the cooking pipeline.
Sparse Plains
The Clamily mid-depth flats. Lower creature density, more open water, and rarer mineral deposits.
Deep Start
The depth-rated descent corridor down to the Void. Where Tadpole crush warnings start firing.
Collector Leviathan Arena
Boss arena. One Collector Leviathan, no respawn. The hardest single-target encounter in the build.
