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.

Hyperion is just a bit more than the outcast of silverdreaM's dragon clan. The bad reputation his breed has for personality had made the other dragons turn a blind eye to him, only considering to look back after silverdreaM and Mystery's Keeper attempted to train him to be more docile as a matured hatchling. He's reserved, and a little snappy, and would rather keep to himself than socialize, but with the training he received, he's quite approachable now.
