The following account was recorded in the agent's log during your transmission: Tangled vines and moss cover a massive stone staircase that spirals down into the darkness of an ancient, subterranean pit. Umm, the air's thick with the scent of damp soil and mold, and it's like the whole place is pressurized, the silence is almost deafening... A thin film of iridescent liquid coats the walls, and somehow it's imbuing the stone with a faint bioluminescence, casting flickerless shadows across the rough-hewn blocks. Water trickles upwards from the bottom of the staircase, where a delicate latticework of calcite crystals seems to be... knitting itself into a slow, geometric dance.
