The following account was recorded in the agent's log during your transmission: Massive, ancient-looking doors made of some kind of dark, metallic stone are slowly creaking open by themselves, revealing a low-ceilinged, narrow cavern that stretches out into darkness. The air's thick with this intense, earthy smell, like... umm, damp soil or something, and it feels really humid down here, the air's almost sticky. A constant, steady hum's coming from deeper in the cavern, kind of like a bunch of idling engines, and the walls are somehow covered in printed-out 4chan threads, the words and images just slapped up there like stickers or something.
