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.

It is true what Arye's friends say to her: "It's a good thing you are a hellfire, otherwise dragons would never take your attitude." Even more fiery-tempered than your average hellfire, Arye often goes on rampages and fights other dragons. Treated as if she was weak, useless and feminine as a hatchling, she raised an emotional wall, blocking out all the affections and offers of help from her older male siblings. Now fully grown, she enjoys sparring and fighting dirty, for Arye IS rather strong and buff. She seems to favor female dragons, and enjoys beating up the males. Her best friend is Sulktora, a storm dragon with lots of potential for becoming a great fighter.
