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.

Meiyo Kasai, meaning Honorable Fire, is a surprisingly docile and gentlemen like dragon for his species. It is thought that he is like this because Hiekka Tulipalo and Burakku Suta went out of their way to raise him. Meiyo wants to be a solider and strongly willed about protecting things, even if its from another friend. He always tries to look at both sides of the story before he takes a side, but sometimes he gets ahead of himself, and defends the wrong side.
