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 to the north is entirely

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

echoes can be heard.
