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.

In the Hellfire Wyvern's society, it is natural that female is superior to the male in every aspects including power and even social status. But Tailorock was much more than that. He was weaker than any other male Hellfire Wyverns. Naturally, females forced him to work every odd job. He couldn't stand those situations anymore. One day, when he realized he had grown enough and there are Hellfire Wyverns that are in similar situation. He decided to change the primitive social structure. To make his race better, he needed much more power. Resisting females' suppression will be very severe to tenuous males. But it is not the time yet. Endure, before the right time comes.
