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.

Naichia is an hot-tempered fighting machine. Her battle and magic skills surpass her mother's by a long shot, which is saying something. She could easily kill a dragon in one fire blast if she became angry and used her full power. When she was a child, she and her father got into a fight, resulting in her losing her temper and seriously injuring him by accident. From that day forward, Naichia has devoted her life to gaining control over her powers and her temper. Her main duty is to work alongside her mother to protect her clan.
