A Dark, Narrow Hallway                                 -      #      - 
(-------------------------------------------------)     W <---(M)---> E
                                                        -      -      -

This hallway is poorly illuminated, making it is difficult to see where
you are walking.  Some of the slabs of granite beneath your feet are loose,
nearly tripping as you duck to avoid the cobwebs hanging low from the
ceiling.  Oddly, the walls are dangerously close together and look as if
they might be getting closer the further you walk down the hallway.
