The following account was recorded in the agent's log during your transmission: Dark, murky water swallows everything, and I'm struggling to keep my eyes open... fatigue's really kicking my ass. The air's heavy with the smell of decay and rot, and I'm pretty sure it's late evening judging by the faint, distant glow of... something. A chunk of the Yonaguni Monument, like, those underwater rock formations off the coast of Japan, just exists here, half-buried in the silt at the bottom of this flooded, abandoned subway tunnel, not corroded or covered in growth, just... pristine. The water's somehow perfectly still.
