The following account was recorded in the agent's log during your transmission: Massive, iridescent stalactites are hanging from the ceiling of a vast underground cavern, reflecting the light of an eerie, pulsing glow that seems to be emanating from the walls themselves. Like, the air's got a heavy, metallic taste to it, and the smell of saltwater's wafting through, despite being what feels like miles beneath the earth's surface. The cavern's floor is a seemingly endless expanse of still, black water that appears to be made of a liquid that's... somehow below absolute zero, judging by the weird, frozen ripples on its surface. Umm, it's dead silent, except for the sound of faint, whispery chanting echoing off the walls.
