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.

Admonitory is given to admonishing others in a "you-know-I'm-right" voice, and she quickly becomes huffy and morose if the target of her admonishment argues back. Normally, other dragons would consider this rather annoying, but for Admonitory, they prefer it over her breed's usual vicious, fiery disposition. Apparently, she was adopted. There was a stigma in the network of Plain Sight attached to adoptees, who're believed to be total weirdos, but Admonitory quickly changed that. There was no effort on her part—many of the judgmental old denizens of Plain Sight suddenly decided that her not growing up with her own kind isn't really so bad.
