Kethel is big and damage-resistant enough to find that comforting. Magic aside, anything solid enough to kill somebody can presumably also be killed as long as you can separate it into enough component parts before they do the same to you, and giant claws and bone plates make that a pretty good bet. "Are they predators or just angry?" Somewhere in the core of Kethel it can't quite shake the idea that sometimes you just gotta eat.
