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.

This dragon has a calm and cool temperament, which was most likely learnt from his mother, a moonstone dragon. However, if he is bothered, he has a high capacity for anger.

Nonetheless, he helps in raising eggs from the volcanic region by lighting nests of wood and coal for them to incubate inside of. He is also rather friendly, so much so that the human within the cave has to keep an aloe vera plant nearby in case he decides to nuzzle her.
