When the Litch summoned the demons from the depths the fire spirits took possession of the carcasses of the dead animals bringing vital fire into their veins. "the Tome of monsters and beasts" describes the Hound as a solitary monster with a macabre appearance: in fact, the skin of these creatures is for the most part drained and burned, the evaporated orbits have been replaced by two flames and instead of the tail a huge tongue of unquenchable fire that he uses to burn everything he tramples, the only desire of this reincarnated demon is to set the world on fire.
