A Winding Hallway                                      -      N      - 
(-------------------------------------------------)     - <---(M)---> E
                                                        -      S      -

This hallway is cut from the rock, and extends as far as you can see in
both directions, until it curves away.  Along the walls are torches, held
against the wall.  The walls have writing across the border, near the
ceiling.  The inscriptions continue all the way down the hall, and never
repeat.
