A Long Hallway                                         NW     -      - 
(-------------------------------------------------)     # <---(M)---> -
                                                        -      S      -

This hallway was not made as neatly as the tunnel to get in.  The walls
are carved into stone, not dirt, which shows how far underground you must
be.  The walls have engravings on them, filled with pictures and words.  The
pictures are strange, and show no coherent resemblance to anything in
particular, and the writing is a script from a language that you have never
seen before.  To the northwest is a glade, and to the south is more of the
hallway.  On the western wall is a door.
