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.

Suuvi has a fiery temper, a fiery passion, and is overall just violently energetic. This makes her a great hunter, but not really a great conversationalist. Everyone knows not to trust anything of value to Suuvi because she absolutely will break it, not due to clumsiness, but a lapse of judgment while venting her anger at the least thing. The most stoic warriors of the group can deal with her, and continue to try to train her to manage her temper, so that it is released only when necessary. Many of the dragons compliment her ability to get the best meat in a hunt; they don't mind that it always ends up shredded, and sometimes slightly seared.
