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.

Suns Flames is a vicious dragon when enraged, but he also has a soft side when mellow. He grew up to be a rogue but decided to join Tribe of the Valley Plateau when he fell in love with Stars Tears. He keeps his feelings to himself to show that he is a strong, vicious dragon, and not a soft, loving dragon like he believes dragons with mates are. He is feared by many animals and isn't afraid to challenge any dragon, especially when they mention he has tiny legs, since he's very sensitive about that.
