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.

Near the Lands of Perils, deep in the vast, desolate desert of Manticula Vex, lives Gorak Barimm, a Hellfire Wyvern exiled from his volcanic dwellings due to his unique, calm behavior. He used to live in a cave near the Horad's Peninsula, until he was lost to a fight with a powerful wizard who desperately wanted to seize the cave for unknown purposes.

Barimm lives for a long time in the desert, and rumor spreads of a lone Hellfire Wyvern lives in a rocky cave, ready to be caught. Many sought to seize him, but all fails due to the harsh environment, and Barimm's fiery defense when they successfully reach his lair.

Even the feared dragon hunters group Baardard Nikhim lost one of their respected leader trying to seal him.
