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.

Frostsfyre is a domineering, arrogant dragon even among Hellfires. She dislikes anyone who challenges her authority, and is quick to pick fights about it. She is, however, loyal to her "underlings" and will not hesitate to protect them and her friends against any threat. She is heavily scarred from all her battles, and few males wish to mate with her for this reason, along with unhappiness at being subservient to her. She is known for her habit of fighting hard and brutally, but rarely kills her opponents unless they are not dragons. Unusually among Hellfires, she is matriarch over her more submissive mother. She often forgets, however, that she only rules over the other Hellfires, leading to many fights for dominance over other dragons.
