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.

Hell's Keeper is thought to be from hell by the pack.  Many keep their distances away from him but a few males think he's awesome.  He loves fire and can do tricks with it too. He is a rather quiet dragon.  Many hatchlings ask him if he is from hell.  He likes to scare them and always says "Yes, I'm Hell's Keeper," which this gave him his name. His best friends name is Magnaize, since they both like fire it is easy for them to get along.  He doesn't talk to leaf dragon types, for he is afraid he'll burn them.
