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.

Adelfos, 'brother' in Greek, is Cheimon Castle's resident Blacksmith. He loves to craft with metal, and he's quite good. His forge is always busy with commissions, but he reserves his best work for residents of his castle.

Adelfos spends almost all his time in his forge, coming out only to visit with his human, Aero, once in a great while. If you want to chat with Adelfos, you have to go to him. Only a few dragons can be in there for a short time, because of this he and the resident Ember dragon have grown very close.
