Hold on. The PDA just updated. Magnetite deposits are interfering with the sonar. No—wait. That's not interference.

They look like Crabsquids, but their heads are elongated. Translucent. I can see smaller organisms swimming inside their skulls. A symbiotic hive mind. The PDA has no data on this species. I'm naming it: Umbracephalus trenchalis .

There's something moving in the sediment. 71288 subnautica

Given that "71288" does not correspond to a standard in-game item, blueprint, or coordinate in Subnautica , it is treated here as a —a distress call or a research memo from a survivor on Planet 4546B. Aurora Survivor Log: Entry 71288 Status: Deep bioluminescent trench | Depth: 350m Subject: Geological anomaly & Leviathan class interaction

Hypothesis: The precursors experimented here. They didn't just study the Sea Emperor. They tried to hybridize it. Whatever grew in this trench... it didn't survive. But its immune response did. The entire trench floor is covered in a gel that neutralizes small infections on contact. If I could synthesize this... Hold on

Correction: There are many things moving.

It just emitted a sonic pulse. My Seamoth's hull integrity dropped to 60%. I'm backing away slowly. Note to self: Do not use sonar. Do not use lights. They are attracted to electromagnetic fields. No—wait

The walls of the trench aren't rock. They're bone . Massive, fossilized rib cages of what must have been an ancient Leviathan class, easily three times the size of a Reaper. And wrapped around these bones? Vines. But not vines like the Creepvine. These pulse. They emit a soft, orange light that matches the wavelength of the Kharaa bacterium's secondary stage.
