This rocky passage is about six feet wide, and at least twice that in

height, allowing a pair to comfortably walk abreast. It is just enough

room to defend oneself with some measure of ease. The walls, floor and

ceiling are made of a dark grey stone marbled with metallic red

veins, and their surfaces are fairly uneven and rough-hewn. Strange

sounds echo throughout these deep tunnels, and the remarkable

similarity of the passages makes it difficult to navigate.
