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.

Nar Kaname is completed devoted to his mate Nar Yuuki and will not allow any other male dragons near her. The two of them made a home for themselves near the land of the magma dragons and are focusing on raising a family of 'pure' lineage.

Since Yuuki spends most of her time sleeping Kaname can often be found stalking around their private nest to ward off intruders. The Hellfire's enjoy their privacy and rarely like to be disturbed, even only allowing the cave mistress near when they wish to talk.
