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.

Cold Hell's Fire was fostered by King ClearSkin and Rawrlet. Because of this her natural temper is lower, although she still fights time to time. She was found, surprisingly, by Zaurko and the older elders right inside the cave as a hatchling. At that time she would growl and start fires a lot, but she turned out alright. Cold Hell's Fire also has a problem: she will sneak off at night and steal from other caves. She wants to mother a few children but doesn't know who she likes, or who likes her.
