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.

A desperate dragon, Yoosra was jealous of how all the other dragons where mating and having their own offspring. She wanted a dragon of her own to call 'child'. One day she forced a seasonal, Redloum, to give her her desire. After mating, Redloum isolated himself from the other dragons, from Yoosra, and from the baby dragon. Yoosra cried out for many days and nights, calling him. But he wouldn't return to her, because as all the dragons where trying to tell her, "He simply doesn't love you."
