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.

Being a male Hellfire, Rufflewing knows he is beat by most other large dragons, especially the females. He is very docile and loyal,(Possibly because he grew up as one of TheMuppyOtter's first dragons, when the cave was quiet and peaceful.), obeying TheMuppyOtter only, with no exceptions. Rufflewing was named when he was a newborn, because his wings were damp and crumpled, like a butterfly first emerging from its chrysalis, fat, wet and wrinkly.
