Rooms

  The roar of the waterfall comes from above the cavern.  Part of the

tunnel here is slick wet stone, but much of the rest is damp dirt.  The

supports keeping the mining tunnel open sag dangerously.  In the middle of

the cavern is a large, stagnant pool of stinking water.  Bubbles

occasionally rise up from the deep of the pool, disturbing the filmy

surface.  Likely an underground spring.  Or then again, maybe a most

unpleasant somethings lair.
