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.

Ogiub is a fierce warrior of Caliagrand's hellfire pack. While he is loyal to the dominant females--so much so that he would sacrifice himself for them--he is petty and aggressive with fellow males, often fighting with them over scraps of food or simply for ranking. Remarkably he is defensive of hatchlings of any gender, and will protect them as much as the matriarchs. He tends to be quiet, preferring to use aggressive snarls instead of words, but has shown himself to be a very thoughtful, intuitive beast. He prefers to stay with his pack, but can be very independent if ever separated.
