  As you slowly swish your way into the moat, numerous creatures come out
of the cracks and eye you hungrily.  Underneath your feet you feel slimy,
unknown creatures swirling about.  Almost as if waiting to get at least some
scraps, once their elders are done with you.  One thing is for certain, this
is not a place for the faint of heart.
