A Winding Hallway                                      NW     -     #

                                                        SW     -     #

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
ceiling.  The inscriptions continue all the way down the hall, and never
repeat.  There is a plain door to the northeast, but to the southeast is a
heavily reinforced door set with huge iron bars through it.  A sign is on
the door to the southeast.
