You find yourself on the floor of a vast cavern.  As you look around, you
see an archway leading westward into what looks like a series of caves. 
Far, far above your head, you can barely make out a hole in the ceiling of
the cavern.  Fallen rocks, stalagtites, and other debris litter the ground. 
Cracks in the surrounding rock formations and walls lead you to believe that
the are is prone to earthquakes.  You notice that the air is noticeably warm
down here.
