The wide ladder leading up to this platform stops, revealing a darkened
alcove above the palace's south wall.  The passage is obviously confined to
the west because of the large marble wall to the west.  The main palace hall
is visible to the north, and the moat, crawling with slimy creatures below
to the south.
