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.

He is very brutal and kills just for the pleasure of killing. He grew up fighting for his life, living in fear of predators much bigger than him. Now that he is big, he takes his revenge on all those that defy him. Even when injured he will reject anyone's help, and he has nearly died several times because of that. He is very reckless and only seeks to please himself. He is consumed so fully by rage and greed that none will try to get close to him, physically or emotionally.
