This room is very dark, fortunately you have a light source so you can
see that you are in a strangely shaped room that has exit going down.  There
are all sorts of horrifying but intriguing sounds coming from below. 
Judging from the deep dragging and shuffling noises, you figure that there
is something big waiting for you just on the other side of the door.
