Serrati Wyverns are a fierce breed of dragon typically found in volcanic areas or in desert scrubland. With their keen vision, these fearsome predators can pick out well-camouflauged prey from the slightest movement. They are named for the double rows of serrated teeth that line their beaks, which allow these wyverns to maintain an unbreakable grip on prey while they tear into their target with deadly hooked claws. Though these dragons are combative with nearly everything, they are surprisingly well-mannered when raising their offspring in communal nests. Males, however, tend to be chased off as soon as eggs are laid.

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.

Heldenhire is a fierce beast who mainly communicates with savage hisses. Her only true ally is a fellow female Seragamma Wyvern named Suvitilado, who she's rarely apart from.

They frequent windy mountain ravines populated by daredevils, and Heldenhire in particular loves action. She's quick to challenge others to fights, and always enjoys a scuffle even if she loses; though vicious, she has some honor and would never severely injure a respectful opponent. She'll sometimes have a moment of "kindness" if it can even be called that, giving hot-headed encouragement to someone weaker. The only time she'll defend others is if the victim is in danger of being killed, and she'll even fiercely expect her own young children to know how to protect themselves.
