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.

Longtail Wingstorm loves her name and is very affectionate to anyone who dares approach her. She is seen rubbing wings with many dragons, both male and female, and is rarely found arguing and hasn't fought a battle in her entire life. She, however, loves to announce her clean record, and is referred to as "The Bragger" by many of her packmates. She was once found playing a dragon sized game of twister. She lost badly to the humans, being too big to fit on the mat.
