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.

The hot-blooded leader of the Ouendan Clan, Ryuuta has a good soul and helps those around him who are in distress by standing up and fighting for them. His strong spirit to overcome any difficulty brings courage to people around him.

When he's not busy with training or helping people out, Ryuuta is sometimes known to watch out for some of the local hatchlings in the area. This, much to the dismay of the commander of the clan, has often lead to him being followed home by orphans most of the time.
