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.

Michael Bayhem loves to blow stuff up. He often proudly describes his plans for the next target by way of waving his wings around and yelling stuff along the lines of "and then it goes BSSSHHH and this goes PCHOOOO BSSHH BFROOOM and then this goes PCHAM and then it all goes up like BFCHOOOOOOOOOM!" Always one for making mundane awesome, he picks out the least likely target and then goes overkill on it.

Reputed to be aggressive and a jerk to others, Bayhem may have a firm hand but others claim he's a joy to be around. He knows that his work is nothing exceptional; it's just what he does best. Senseless action is his forte and he even pokes fun at himself for it. "Awesome twig! BOOM! Awesome boulder! BOOM!" If they aren't fleeing for their lives, many enjoy watching the spectacle because, well, explosions.
