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.

Revakah is a truly feral Hellfire Wyvern. She is just as short-tempered and aggressive as one may expect from a wild member of her species, despite the fact she was raised from an egg in Silvora's cave. To keep her from bullying the other dragons in the cave, especially the male Hellfire Wyverns, Silvora now takes Revakah on regular training sessions which allow her to fly around and destroy targets. With her destructive habits and energetic nature being satisfied, her demeanor towards the other dragons has improved.
