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.

Fellra the Dangerous is the third mate to Sun Devil the Ruthless. She, like him, is known for her violent disposition and has actually been ganged up on by both Helen of Hellfire and Checkered Violence to keep her in line. Tired of trying to challenge her way to the top, she became the last mate to Sun Devil as he was in search of a strong mate before he continued his family line. Though technically Sun Devil has the last say in anything, if it is not family planning or hunting the decision-making is left to the females. Since both Moon Flower and Neliea are gentle in nature and have no reason to challenge Fellra, all is typically well in the cave.
