Here, the hallway is crumbling very badly.  Ahead it seems the twisting
and winding of the hallway has ceased and becomes a straight path.  Rocks
and dirt seem to fall from the ceiling at your every step.  West leads back
to the entrance of the twisty hallway.  To the southeast a very faint light
can be seen.
