Kezeroth

Kezeroth, the World-Ender and Karok’s brother, seeks to destroy Lore rather than conquer it. Athon sacrificed his life to seal him in ice, but Karok awakens him after only four years. Kezeroth is furious that Quetzal’s comet will not return within his lifetime and distrusts Karok’s claim that Quetzal is dead. He rejects his brother’s offer of conquest and attacks him; Karok later binds him with magic to force his service.
