This small room is used by the guards to get to and from their guard
post.  It is bare, and you can see clean stone around you.  Strangely, the
floor is made of packed dirt, and the whole room smells of soil.  When both
doors are shut, it becomes very dark in here.  Up from here is the guard's
walk, and to the west is a hallway in the castle.
