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.

Kerzarkocel was found in the abandoned pile by Adertiqolva, who raised him into the proud Hellfire he is today. At some point along the line, the other dragons noticed that his distinctive laugh was rather odd, and one of them coined the nickname Kackle. Kerzarkocel knows the name is not demeaning when said by his cave-mates, so he bears it fairly patiently. This has caused a bit of a rift between him and the others though. The only one to bridge that gap is his mate, Gingherdia (Girn).

Girn is very moody and fierce, something that Kackle bears daily. Kackle is very close to Gingherdia, who does have a softer (rarely shown) side. They have had one egg, but due to their many, bothersome ancestors, they have agreed not to have any more children. They would have kept the one they had, but they quickly grew tired of the pesky curiosity from their weaker kindred. Knowing the egg would fare better in another's hands, they left it in the abandoned pile.
