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.

Laruo was cast out of his pack for disobedience to the alpha female. This did little at first to help his already vicious disposition, and one of his first acts was to gather a flock of dragons—mostly pygmy dragons, with a few drakes—that he could bully as he had been bullied. Not being completely heartless, though, he soon developed genuine fondness for the rest of his flock, eventually becoming more of a (mostly) benevolent protector.
