At the end of 8-3 epic quests, it was revealed that the Chieftain of the Trocks clan was possessed by an unknown force, explaining why they attack Sander.
Trocks are burrowing race that feeds on rocks. Trock's Lair is filled with tunnels, much like an ant colony.
Chieftain Trockta claims that the Trocks only speak to strong humans.
Trocks originally lived in Parugo mountain before Calluso tribe drove them out.
Karis promised the Trocks that she would help them retake Parugo mountain. Karis gave Trockta an amulet as a token of this promise. However, the amulet was actually a demon tool that allowed Karis to control Trockta.
