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.

Orphaned as a hatchling, Junan holds an inherent grudge against other Hellfire Wyverns. However, as she was raised to adulthood by dragons not of her species, she has grown to trust the members of her family. She guards the sections of the caves that Sylvain's family occupies, and is fiercely loyal to her fellow brothers and sisters. However, for all her skills and bravery in combat, she still becomes agitated when visiting the abandoned eggs scattered in front of the caves.
