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.

Demigon was abandoned long ago by his parents by reasons unbeknownst to him. When he hatched, it was out of desperation. The moment he hatched, Demigon ran, feeling the heat and barely avoiding a river of magma from an erupting heat-vent. His first sight in the world was red flames being thrown into the sky by dragons and mountains alike.

He was not alone for long however, as a few months later, he began to fight other hatchlings, and occasionally joining forces with them to steal from adult dragons. For a time, they watched him suspiciously due to the ferocious nature of his breed. They stopped once they realised that he had honour, and treating everyone above himself.

From those days he learned many things, and has many tales. His greatest story is how he 'recruited' his future mate, Vallelunga, into his circle. As time passed, some of his fellows died before maturity, but Vallelunga and Demigon always overcame the odds, becoming closer and rarely leaving each other's side.
