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.

Valencia was, as a young hatchling, a typical aggressive little Hellfire who truly deserved the breed name. However, while she was still tiny and before she had developed the icy blue coloration that makes her gender obvious, she was taken from her nest, exchanged for a rare dragon egg, and put under the care of a Summer dragon. For several days of this, she refused food, and once she finally settled in, she had been rather startled by the experience, and between this and her new foster parent, she became rather quiet and sweet, though her old attitude comes back when she's angered.
