Edge of the Empire
The apex predators of the Kashyyyk Shadowlands
Terentatek resembled rancors, except they had a number of spines growing from their backs and a pair of flaps, or tusk-like projections attached to their mouths. They also had massive claws (four to a hand). The tusks and claws of a terentatek were highly venomous. It was theorized that they were once rancors, subjected to mutations by the Sith, and that when the dark side was weak in the galaxy, terentatek would hibernate and remain dormant for many years, only to return when the dark side was strong again.
