A Trail in the Crystal City                            -      N      -

This small trail leads around the city by the small alcoves that were
seen traversing the stairway.  Powerful magic radiates from the alcoves to
the north and south.  Light filters through the crystal buildings from some
unknown source.  The trail leads west to the stairwell, and east to the
cavern wall.
