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.

Swallow always seems so fed up with everything, especially his mess of a family. He's probably the laziest child of Ballet and Eos and definitely the laziest Swallowtail on his home. He has the mentality of a nihilist, hating or denying the meaning of everyone and everything. Carrying a conversation with him is nearly impossible, as he quickly loses attention and interest for anything happening around him. Though he doesn't tend to move around a whole lot, Swallow still retains the acrobatic talents his breed is known for. He very rarely tests these abilities, though. As with all things, he fails to see the meaning of it and will usually pass up the opportunity to go flying. It's a real shame since the few times he has spread his wings are a sight to behold. He may actually surpass his famous father in terms of skill.
