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.

After the growth of her clan's vicious Hellfire wyvern population, Caliagrand helped keep them in order by becoming the Baroness of a small pack (who refer to her as the Alpha). This pack is often vicious and abides by traditional Hellfire behaviors, so though she was raised kindly, Caliagrand has become a stern and ferocious leader who takes no sass from her subordinates. Her friends are often confused as to why she goes to the work of leading such a troublesome group, but Cal admits she has an empathy for them, like they're all her rebellious kids. Her and her small pack function independently of the Clan (except when compromises have to be made), and they govern a small claim of land within the Clan's expansive territory.
