Hellfire Wyverns are so named for their foul tempers and fiery visages. Their social structure places all females above all males, due to superior physical characteristics and violent dispositions. Forced subservience of the males causes them to become vicious, petty, antisocial, and passive-aggressive compared to the aggressive and social females. However, orphaned hatchlings raised by foster parents of another species can develop surprisingly even tempers and mellow dispositions, proving that their defining unpleasant nature is, in fact, a learned behavior.

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.

Much more serious and reserved than his younger Green brother, this dragon grew up faster than most when their parents died and he was put in charge of raising his younger sibling. He doesn't trust easily, but is unfailingly loyal to the very few who have managed to gain his trust. They lived in the wild until a prominent, wealthy dragon noticed their skill in the Arena and offered them sponsorship in the official competition. Now the two siblings, along with their friend, the Avatar Korrastorm, are quickly rising through the ranks of the Pro-Bending Tournament, thanks in part to his adept usage of the fire element.
