Description
Athachs are giant humanoid and stand 18' tall. Each has hideous but recognizable features, a malformed body, and a third arm in the center of its chest.
These huge monsters are quite stupid and ill tempered. They live in small families, sheltering in caves, and beating on one another when not hunting for meat. (They consider humans to be meat.) They love gems and jewelry and, if an offer is good enough, will accept such in return for not attacking travelers.
