Sayormi

A mysterious race who are believed to be ghosts that haunt the lower regions of the Kkowir Forest. The Wookiees of the Kerritamba Tribe often fought with the Sayormi who they believed constantly searched for blood as evidenced by the bodies of humanoid (which included Wookiee) bodies that hung outside their territory.

The Sayormi are actually an ancient race of humanoids who have made this deep level of the Forest their home which they defend ferociously. They worshipped a dead patheon of deities and tamed some of the wild life for their use.
