The following account was recorded in the agent's log during your transmission: Dark, twisted mangrove roots erupt from the silty seafloor, forming a labyrinth of narrow tunnels and caverns that somehow seem to shift and change layout as I move through them. Umm, the air's heavy with the stench of rotting fish and the pressure's intense, like being crushed by an invisible weight... Water trickles downward from above, yet the sound of it seems to be coming from all directions at once, and an unearthly, sickly green bioluminescence clings to every surface, casting an eerie glow on the silt and debris. The roots seem to be drinking in the light, growing thicker and more twisted by the second.
