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.

FlamingMetalTiger is a unique Hellfire Wyvern. Because his mother has such an unpleasant temperament, FlamingMetalTiger's was hand-raised by his owner. His mother, PureFlamingMetal, wasn't interesting in raising an egg anyway; she left the cave for a year after his egg was laid. FlamingMetalTiger is actually quite sweet for his species, though he does have a wicked temper. He's one of the nicest Hellfire Wyverns around, though that isn't saying much. But FlamingMetalTiger can certainly be trusted not to attack anyone for no reason.
