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.

Paperflight is deeply in tune with the migration patterns of the birds that pass through his territory. He has somehow managed to befriend many of them and can often be seen flying through the air with flocks of birds whose trust he's earned. Many are confused by this habit and think the birds would be better off as food, but Paperflight prefers to watch and learn from them instead. This truly has made him very skilled, and he is adept with a variety of flight patterns that he's learned from his feathered friends, with which he can easily evade any threat.
