This massive crystal cavern fills you with a sense of awe and dread. 
You are convinced that this place is completely unsafe, and feel the urgent
need to get away as soon as possible.  Three exits to the north present
themselves to you.  From the northwest, a fog rolls in.  From the northeast,
blasts of hot air blow in, warming the room.  From the north, utter silence.
