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.

Matriarch of a flight of Hellfires nestled deep within a mighty mountain range, Zyrix's resolve is steel, and her rule absolute. Having a near all-encompassing hate and distrust for dragons that she does not deem worthy, she will actively order the eradication of those she feels hinders her cause: the complete and unyielding rule of dragons over all other species. She has chosen the young female Vixzin as her temporary heir; however, the more she studies the young prodigy, the more she feels she may have made a mistake, and one which can easily be corrected by ending the other's life.
