Entrance to the Hall of Constellations                 -      N      -

A sign on the wall informs you that there these two passages both contain
the soul essences of the constellations in them.  The southwestern path is
rather quiet and seems to be an easy route, the southeastern one, more noisy
and sinister looking.  The exit back to the Zodiac passage lies to the
north.
