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.

Santa Paula was raised among a group of her type and moved out after her wings had fully developed. Her new family, a huge assortment of dragons, don't tolerate the hellfire wyvern demeanor. Their strength in numbers always beating her viciousness, Santa Paula had to either learn to be nice or remain in solitude. To her delight, she met a bronze-colored dragon who didn't seem to mind doing whatever she wanted, and for a while, she'd singe and snap and boss him around, while he patiently obliged. Confused again by the conspicuous lack of passive aggressiveness, Santa Paula eventually decided that "all that fiery abuse on a moron like Char-Face isn't worth the energy" and mellowed down a great deal, even toward other dragons. She and that particular male are together often, though one would be hard pressed to have her admit that she likes him quite a lot.
