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.

Thalma is a hot-headed girl who takes pride in her appearance. Though her upbringing lead to much approval by Elroyson, a rather arrogant Monarch himself, Zooey'a doesn't think she's done well. Headstrong personalities are a common trait in Hellfire Wyverns and that is clearly seen in Thalma. A skilled flyer, Thalma is a tad brutish and loves to show off. She is mates with Elroyson, whom her father, Bricello, has known for a while. Thalma is beautiful when she is kind and cruel when she is not. She has a strong connection with Bricello and she enjoys impressing him. Though she longs for a younger male to take advantage of, Thalma is content in her owner, Reikudi's, cave. Thalma can be as cold as ice, as warm as a flame and as moderate as can be at several different times. When flying, she appears much slimmer than she does when she is standing, underbelly brushing the ground. Despite being beastly, Thalma is undyingly loyal, and would do anything to save those she holds dear to her.
