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.

Akarui was taken in by the clan, after their master brought in the egg. Having seen hellfire wyverns before, Suki had one of the pink dragons influence the egg gently, as she had no intentions of her new addition becoming male and being pushed around by all other hellfire wyverns. Once she matured, her master named her, in Japanese, Akarui Kaen, 'Bright Flame.' A smart, happy young dragon, she has heard of other hellfire's behaviors, and is completely appalled by how they act, but enjoys the fact that the females are on top of the food chain for hellfires.
