The red-veined grey stone tunnel here is covered in most places by a

smooth, organic-looking substance. The strange material is a dark

violet, almost black, and is lightly sticky and warm to the touch. A

faint smell, not unpleasant, wafts up from the stuff, though it does

not look entirely wholesome. The tunnel through the floor here is

entirely coated with the hard violet substance, and from within,

chittering echoes can be heard.
