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.

Sapience was found by RunningAir as an egg, and Dark Card took up to the hatchling that burst forth from it immediately. He raised the little hellfire wyvern himself, and was happy to act as if it were his own child. Because Sapience was raised by the Vampire dragon, and not his own kind, he grew up to be fairly mild in temperament, though he is still prone small outbursts of anger towards anyone that defies him- and has a slight habit of helping Dark Card hunt. He took up to Vulcan Styxin in his youth, and became her mate some time later. They fit together well.
