You have come across a cavern of massive proportions.  Crystal glitters
everywhere.  You are high above the cavern floor on a ledge that looks down
upon it.  It seems that hundreds of feet separate you and the ground, and
your stomach twitches at the sight.  The ledge leads around the edge of the
cavern, both east and west, to a stairway that leads down to the floor.
