You are in a twisting corridor made of roughly worked plain gray stone. 
Cobwebs drape the room from floor to ceiling and from wall to wall.  You
cringe with revulsion as you sweep them aside so that you may pass.  As you
move the cobwebs aside, you see that the stone is cracked and broken, giving
layer of dust, you can just barely make out a brightly-colored mosaic of red
tiles set in a most disturbing pattern in the floor.  The corridor continues
to the west and south.
