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.

Sisket spends most of his time venturing off to the mountains with Luzjo, a stone dragon, and sometimes Shivan, a Tri-horn Wyvern. He tends to enjoy rough housing with the xenowyrms, but often gets someone hurt in the process. When he is angry, he starts fires in the forest and we have to call for some help from our water dragons. We don't usually see him for a few hours after, but then he will come back and go back to nuzzling the eggs and keeping them warm while he waits for Luzjo to venture off and play in the wilderness.
