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.

Delremaine makes it her monthly duty to terrorize one specific village, which was settled by humans right near her pack, more importantly her precious nest. The humans really won't get the hint; they don't realize that the huge rocky cliff is the home to dozens of Hellfire Wyverns, which Delremaine is the leader of. Though it is a small village, she sees it as a hindrance and a danger to her young and plans to evict the humans, either by force or by scaring them into moving away.

Delremaine is fast and agile in the air, but is unsteady and vulnerable on the ground. She is capable of grabbing a small house in her talons and ripping it from it's foundations to drop it from great heights. Though she may seem like a heartlessly cruel wyvern with a temper to match, Delremaine is a good leader and an even better mother.
