Eastern Branch of the Atrium                           -      N      -

An extended version of the atrium stretches to the east, open to the sky
and paved with a long, aesthetically attractive mosaic.  The design under
you is of the denizens of the sea, variously positioned so that regardless
of the direction from which one walks into the room the figures appear right
side up.  To your south are the thick palace walls, towering a few feet
above you.  The path continues to the east and west from here.  
A sneaky slave trader is here looking for potential buyers.
