This small platform juts out from the side of a massive circular chamber.
The most obvious feature of the cavern is the fact that it is filled with
fire, rising up from far below.  It looks like the ledge you are standing on
ran all the way around the room at one point, but the constant heat has
caused it to break apart in two places.  You can make your way along the
ledge to the east or climb through the large hole in the wall to the north. 
You should also be able to jump down to the other part of the ledge below to
the west with ease.
