The ground seem more stable here, as though the bog below was very thick
and old.  Strange plants grow and intertwine themselves around the ancient
stumps of dead stalagmites.  The echoes of creatures in the dark ring
throughout the cavern.  A Black ooze bubbles up from the ground below giving
off a sweet acrid odor.  There is a huge tree that lacks any green in it
what-so-ever, its strange white corpse haunts your every move.  
A thorny, red-veined vine twines its way around your feet.
