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.

A member of the illustrious Hellfire Clan, who claims to be the original Hellfire Dragons, Rowena takes pride in her heritage. However, having been stolen away from her ancestral home, she did not grow up cruel and vicious. She still has a wicked temper, and woe to those who upset her.

As a dragon with roots in the Fire element, her main breath weapon is a jet of fire shot from her mouth. However, the special attribute about female Hellfire Dragons' breath is that while it is definitely fire, it causes severe frostbite on contact.

Her favorite pastime is to gather together large piles of flammable objects and use her breath to create an eerie blue bonfire. This is especially useful on Halloween when her adoptive brothers and sisters gather together to tell scary stories to each other.
