Piercer - room of stalagtites, half of them piercers As you enter the murkey cave and your eyes adjust to the gloom you see a large cavern with stalagtites clinging from the ceiling. Across the cavern you can see a passage leading deeper into the hill
Dragonet, Firedrake - mated pair of drakes in a room. nest in a recess. 50% chance of attacking if group leaves them alone. recess is easily blocked by a wall of stone, etc. The passage widens into a cavern, smaller than the one before it. In the far wall of the cavern you can see a niche that holds two small red, winged lizards. There is a second passage going further into the cave complex.
Mudmen - cave is half filled with water, only a foot or so deep, easy to wade across, home to a group of mudmen, got room enough to stand on either end. This cavern has a wide, shallow pond covering most of the floor. The pond looks to be shallow and easily waded through.
gelatinous cube - the main path will rise over a wall for the dragon, underneath a smaller passage will have been cut through the obstacle. trapped inside the passage is a gelatenous cube. on either side of the passage will be a hidden switch which, when tripped will lower the cube and slide a floor across for safe passage.
Mimic - 3rd from last room. several treasure chest mimics. group should according to warning not even touch. Yes again you enter into a small cavern, this one looking like it is a storehouse for some of the dragon's treasure. The cave is littered with piles of coins and chests.
trap, umberhulk - 2nd to last room. 3 floor traps in room, one at each end and one in the middle. when triggered raise a false wall. inside is metal cage with 1-2 umberhulks. umberhulks will make a big ol' noise and stun anyone who looks at them, causing guards to come investigate. As you enter into this cave you are struck by the caviness of it all. And by the fact that it is thrillingly empty.
drow - last room. drow guards hired by dragon and serving as guards in good faith to keep the dragon out of bothering the drow if they should come to the surface for any reason. they won't let the group go through. group will have to find a way to force past them. once past them into the dragon's chamber the dragon will stop them from attacking. This cave looks much like the previous ones, but this one differs slightly with the presence of four drow in it.
