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.

Despite his breed of dragon, Hellfire is still obedient... to his biological parents. Even though he's a fully mature dragon, he still throws fits when he can't have something his way, as strange as it is, and will even travel with the two dragons wherever they go.

Marquis is the sympathetic mother while Coal Cracker is the short-tempered father; if Hellfire is being upset, Marquis tries to calm him. Coal will just beat his Hellhorse offspring over his head with his tail, having no patience for an adult dragon's immaturity.

Despite Hellfire's parents being the polar opposites of each other, they occasionally cooperate together to take care of their ill-tempered son and keep him in check.
