Needlerock Chasm is a chasm just north of Needlerock Slag in Deepholm. It is here the stone troggs main settlement is located. Below the rock formations is a large pool of water where giant mushrooms grow. The stone trogg fungalmancers sprout fungal giants from them and send them to attack the Earthen.
Slate Quicksand is found in the south end with a small group of geomancers waiting to stop this activity.
