The walls were roughly cut from the stone around you, supported by wooden
beams.  They are covered in dirt and grime.  A short breeze of air from
farther down the corridor turns your stomach, and your eyes start to water
from the smell.  You can hear loud shouts and the rattle of chains further
up the corridor.
