Water Rising Cave

In this campagin the players will find themselves at an ancient castle ruin on an isolated lake.  After some investigation they will find that there is a sinkhole under the castle courtyard leading into the earth.  They will decent futher in further down spiral stair cases until they reach the bottom level.  At this time a monster will break to the cave walls causing water to rush in.  Players will need to quickly ascend while they try to avoid the creature that will try to grapple and drown them.   They must avoid traps and difficult terrian in the form of loose rocks and debris.

I added hide volumes for each layer to make it easier for zoom levels.  If these are problem they can be deleted.
