You are at a guard's post.  The cold and damp walls tower high all around
you.  The carpeted floor is covered with a decorated carpet that extends to
the doorway.  An oddly shaped opening is in the north wall that serves as
lookout for the guards.  The slightest sound echoes of the walls, which
makes a chill travel down your spine.  The exit is back to the north.
