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.

Iridescent Fyre isn't simply a bad-tempered dragon who breathes blue fire. She's beautiful, terrible, fearsome, mysterious, clever, proud, majestic and she will hunt down and destroy anyone who says otherwise. Her name comes from the shimmer her wings possess, lending her an almost ethereal air as she swoops down on her prey. Many of those who attempted to travel through her mountain domain died frozen in terror and awe, unable to run, as death descended.

But despite her temper, attitude or appearance, Iridescent Fyre cannot be classified as good nor evil, kind or maleficent. She simply is.
