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.

Lucky's father was raised by a dragon tamer who valued him for his shimmering silver scales, his rarity, and his almost unrivaled intellect. However, this tamer had no suitable mate for him! 5ilence managed to find Lucky's mother, a gorgeous and fairly gentle Hellfire descended from the Great Thuweds, and sent her to live with the other tamer. Lucky's name comes from the first thing she heard while she was in her egg, before she was given to 5ilence out of gratitude—"Thank my lucky star that they liked each other!"
