The ruins seem to thin out towards this end of the cavern, and the ground
slopes sharply upwards to the north towards a higher plateau.  While it is
difficult to see from down here, there appear to be a number of large and
impressive buildings up above you.  They look a lot nicer than anything in
the actual city, and you decide that they might warrant a closer look. 
However, there doesn't seem to be any way up from here, you'll probably have
to find another way in through the city itself.
