Hellhorse Dragons are foul-tempered, spirited creatures with tempestuous and violent dispositions. Torrents of scorching flames erupt from their bodies and can easily set their surroundings ablaze. Highly aggressive and territorial toward other dragon species, Hellhorses will tolerate others as long as they believe the association to be beneficial. Such alliances are tenuous in nature and frequently short-lived, as the slightest disagreement can easily escalate into a full-out brawl.

Dragons are highly-intelligent reptilian creatures that—from a human perspective, at least—appear to live forever. Many different varieties of dragon exist, each with their own unique qualities, habitats, and behavior. Adolescence in dragons is usually marked by the growth of a hatchling’s wings, although not all breeds of dragons grow wings and some breeds have other traits that indicate the beginning of maturation. In Galsreim, dragons and humans coexist peacefully.

Devil is Belladonna and Ennar's youngest child.

He is energetic, childish, stubborn, and a bit stupid.

Almost anyone in the Clan envies him for belonging to a rare species, but he doesn't seem to notice it, or care for it, actually.

He idolizes Okistrasz in an evident way: he is always by Oki's side, he follows him no matter were he goes and so. He thinks that Oki is awesome and wants to be like him.
