This medium-sized room, with its smooth stone walls, looks a lot like the
rest of the chambers you've seen in the area.  However, the floor is
especially rocky, and there are many cracks and crevasses in the ground. 
You notice that some of the holes are covered with strange white webs, and
is a large hole in the wall to the north, leading down into a small
indentation where you might be able to hide.
