The following account was recorded in the agent's log during your transmission: A dense cluster of bioluminescent mushrooms is covering the walls of some kind of... ancient, underwater cave, I guess, like, a flooded temple. The air's super cold, and the pressure's intense – uh, it's gotta be hundreds of feet below the surface – and it's pitch black except for the glowing mushrooms, casting this eerie, blue-green light on everything. The water's somehow flowing upwards, towards the surface, like, against gravity or something, and it's perfectly still, no currents or turbulence, just... steadily rising. The silence is almost deafening.
