Teelget
Teelget was a quadruped with antlers on his head. He was predatory and round shaped with few features. The hero Nayenezgani killed it by using a gopher to burrow into its chest and he shot its heart with an arrow made of chain lightning. Teelget got angry and ripped apart his own body trying to get to Nayenezgani.
