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.

Beautiful as she is aggressive, Morgan doesn't tolerate many of her tamer's dragons, but she is extremely close to and fond of her mother, father, and tamer. Her tamer supposes that Morgan doesn't look down on her Wyvern father because he helped to take care of her when she was young. Morgan is easily enraptured by her mother's dancing, which often helped her go to sleep when she was a hatchling. Morgan loves to hunt, but can be possessive over her kills.
