The water
Warm water behind a jammed signal — the deepest band charted, reached only once the Breachstone's siege unseals it. The darkest water in the game and the most scattering, so a lamp here throws the least clean light of anywhere you can dive.

Hazards
Entry itself is the hazard: the grotto stays sealed behind a real, multi-day siege rather than a depth or a key. Full mechanics in The Breachstone.
