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.

Like most of her kind, Da'rio is aggressive and hot-tempered. But, being raised by Artemis the Human, she is manageable and once a dragon gains her trust, she is a valuable friend. This trust is not easily won however, and if it is broken, the hopes of repairing it are slim to nonexistent. Despite her angry tendencies, Da'rio enjoys watching eggs and hatchlings. She and Lerha incubate eggs and keep young dragons warm.
