A Long Hallway                                         -      -     NE

                                                        SW     #      -

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 northeast and southwest is more of the hallway.  On the
south wall is a door.
