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.

Casualty is mostly known for being the enduring mate of Magma dragon, Stukov. She is quite true to her breed's personality, being a generally hot-tempered, belligerent creature. She nags Stukov constantly about how much time he spends with his best friend-- Bipolar the Ice dragon-- to no avail. It wouldn't be farfetched to say that she is jealous over Stukov's attention, though it is much more likely that she is just aggressive and confrontational. Casualty rarely, if ever, appears to enjoy the company of her mate, and it is no secret that she despises Bipolar.
