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.

Infernoxus was once another species of dragon, but then he broke into Hell to retrieve the soul of his lost mate, a dragon who terrorized an entire countryside by burning down villages, eating the inhabitants, and stealing their riches. Infernoxus was nowhere near as evil as her, yet he still loved her, or he thought he did. He now realizes it was more of an obsession that consumed him so much he didn't realize the dangers he faced, and he was morphed by the fires of Hell into what is known as a hellfire wyvern. He now walks the earth living with his past mistakes.
