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.

Abira, whose name means "strong" in Hebrew, lives up to her name in every sense of it. Willful and stubborn at times, she can be warm and caring when it suits her. She hates having to care for the hatchlings, and prefers to be alone most of the time, entertaining herself by blowing small puffs of smoke out of her nose and mouth, flying loop-de-loops and whirling around madly in midair. She is not lacking in brute strength, and will fight fiercely if angered.
