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.

You Can't Have is a pessimist.  He spent his childhood bullied by the aggressive females in his clan, completely destroying his sense of self esteem, and he is convinced that any dragon who can maintain a cheerful disposition is a liar or a fool.  This has put him at odds with a happy-go-lucky, prankster albino dragon named Ghost in the Shell, who loves to challenge his gloomy world view with long philosophical debates.  Ghost is convinced that there's a proud, strong dragon hidden inside YCH somewhere, but he has yet to believe her.
