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.  Through
a thick 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.  A cold,
chill air wafts in from the east.  The corridor continues to the east and
west.  
    You sense a hidden life form in the area.
  You can see the faint red outline of something moving around the area.
