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.

Darklight Fury is actually very sneaky: she acts nice to other dragons to get what she wants then, when she has it, she removes the facade, becoming extremely aggressive, chasing away everyone and everything trying to scare them away.

Darklight Fury is training under Darklight Flames, a Hellfire Wyvern that's one of the Guardians of Heart, powerful dragons that guard the Human, eggs and wounded and weak dragons and hatchings.

Fury wants to be a Guardian of Heart one day, but others say that she might mess up the job; this makes her want to be one even more.
