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.

Hiddenspark is a pure-bred Hellfire, though he has not had much of a chance to interact with other Hellfire dragons in his lifetime. He was picked from the magma of a volcano and joined into his egg group in which he grew up with; Airset, Sundull, and Tinderflame. Hiddenspark has a very peculiar liking to Sundull, though she doesn't notice, as her abilities to cast magic interests him, and he plans to become mates with the talented dragon in the future. Hiddenspark enjoys burning the places in which he rests and separating himself from the rest of his group, but despite this he still travels alongside his brethren and comes to their sides in their times of need.
