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.

Fluegas is a Hellfire Wyvern that was recruited from the main cave as an egg. Although not raised by other Hellfire Wyverns, she still developed a hot-headed attitude. She often argues with others and often has vicious fights with some of them. Fluegas doesn't think very much—she always says "Attack now and think later." Despite her not so nice behavior, she has a mate. Much to the surprise of the whole clan, her mate is Flannio, a very happy-go-lucky dragon who loves her very much. She is a member of the elite force of the Iron Roar clan.
