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.

Hellfire Wyverns are known for their foul tempers, but if raised in a friendly envioronment, they can be fairly mild mannered. Magmorta is living proof that the temper can be genetic. She was raised my Mama Dracor and McFlufferbutts, the two nicest dragons in the clan, but still, she's very ill tempered. She hangs around Tesela, because the two actually understand each other's anger and are actually friendly towards each other.

Although, sometimes they will get into a playful fight, which turns very aggressive very fast. The two will also team up to pick fights with others, but the fight will turn into one against the two friends.
