The passageway begins to narrow the further you go along.  Your light
begins to cast wavering shadows on the dirt walls and the ground is damp. 
Little bugs crawl all over and cobwebs hang from the ceiling.  There are
half rotted wooden posts holding up the walls, but they don't look like they
will last much longer.  The path slopes downward steeply to the west.  
A giant malformed rat bares its fangs at you.
