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.

Zembueh has what might be described as serious anger management issues. It is a minor miracle to see her with anything other than a scowl on her face, and a downright cause for celebration to get a half-way civil word out of her. When something irritates her—and most things do—she reacts with violence, her powerful physique making the ire all the more formidable. In short, she spends much of her time destroying things in order to keep herself from destroying other dragons; you see, she is not cruel and does her best to avoid damaging any of her cave-mates. Nonetheless, she is encouraged to spend as much time away from the cave as possible, so as not to gouge chunks out of the rock-face. The only dragon whose presence she suffers is her mate, Shepht, who somehow managed to slip under her prickly exterior when she wasn't looking and lodged himself under her skin.
