Somewhere in a hypothetical game

    You are in a room dimly lit only by the full moon shining through a
small window high on the eastern wall. A thick swirling mist several
inches thick cloaks the floor. Many fascinating objects and items of
furniture festooned with cobwebs fill the room. 
    Well, no, not really! Actually this location is empty and exists for
no reason other than to have a place to start from in this demonstration.
