Further into the large cavern complex, you notice that small pieces of
droppings are all around the floors, and walls.  The cavern are were created
by the action of running water flowing through the cave, making it wider and
higher.  Towering stalagtites pierce into the cavern through the darkness,
and stalagmites struggle to reach the high ceiling above.  The only sounds
that can be heard are the timed drops of water and the cries from an unseen
creature, lurking in the shadows.
