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.

Blizzburn is one of the biggest dragons in this cave. She is bad tempered and usually will challenge other dragons to battle to vent her anger, usually beating them within an inch of their lives. She is covered in blue flames, and due to her extremely bad temper, she is not very well liked. She has struck up a close friendship with Cyndrax, despite them being polar opposites. Cyndrax is the only dragon that can calm Blizzburn's temper, usually saving a few dragons from being beat up. She is mated to Chirius.
