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.

Kessunder's flames burn bright and strong, as she is a very passionate dragon. She takes her hunting, strength, and fighting ability very seriously and is not one to joke around. She tends to attract more mature dragons as friends, and the other ones brush her off as pretentious or arrogant. She lets no one put her down, for she is very confident at what she does. She may never stop practicing her strengths and protecting her weaknesses until she dies, but with her progress, that will take a very, very long time.
