Swallowtail Dragons are graceful and quick flyers, much like their namesake bird. They are capable of precise aerial acrobatics, and can reach very high altitudes. Because of this, humans observing these dragons are often astonished at how large they are when confronted up close. A Swallowtail’s diet consists of insects and small mammals plentiful in temperate forests. These dragons are also made remarkable by their paper-thin wing membranes, which allow light to pass through, creating an astonishing effect on starry nights.

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.

Charles is one of the many dragons rescued and nurtured by the wide ranging clan of humans founded by AnselaJonla. His egg was found in a forest and taken to a hatchery to be raised.

Once he matured, he found his lifemate, a Seasonal dragon, among the other AnselaJonla dragons. In the tradition of the AnselaJonla flock, both dragons took the same name, Calder, to pass down to any of their offspring that remained within the flock.

Charles travels with his mate between the hatcheries. He likes to create patterns of light on the ground below with his translucent wings. When threatened he will dive on his opponent, copying the Falconiforms of the flock.
