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.

Subsurface fled from his all-Hellfire pack long before he had a chance to become irreparably angry and nasty. Even after years of stay in his current motley group, he still has to work on some old habits like eating eggs on the Not Allowed to Eat list (because he can't read) and huffing fire at cabinet folks who irk him. He likes to practice being assertive to others, although he would probably be stumped if asked what the difference between assertiveness and ferocity is. Subsurface is wooing (or is attempting to woo) a dragon with a beautiful gleam and a talent for snark, under the assumption that "she's a wyvern, I'm a wyvern, we're both confident and dignified, it'll be easy".
