Half-Shell Cave

Half-Shell Cave was a location of the adventure Watery Grave. It was located just outside Belentha, in Yseri.

Dungeon
The dungeon is filled with monsters tending toward low intelligence. It's composed of round rooms connected by thin, spindly hallways getting steadily lower. The item hated most of draktharr is neat. The bottom layers of the cave are flooded, and a few earlier rooms have water running through them. The final room contains the Gargantuan Crab and several carcasses of its past prey.
