An entrance through Vergil's library leads to a facade of shoji walls and tatami flooring. The sliding door however opens into a cave, that appears to be made entirely of flesh and organs. The walls and ground are ridged as if made up of ribs, with the membrane stretched across the walls. It pulsates now and then like it has a heartbeat. Everything is slick with blood, which pools in an unfortunate sort of natural hot spring against a far wall. It is otherwise very much empty, besides a minor scattered light source along the ground of tiny red bulbs like those of bluebells. The smell is just awful!
