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.

SkyTails is a playful Swallowtail dragon who does not have a set mate. He is usually swooping about through the biomes of the dragon cave, taking in abandoned eggs and hatchlings. He is almost always found in the jungle, forest or alpine, but no matter how much he tries to hide it, he has a bit of a crush on the electric dragon Em, and will sit and watch her fly through the windy mountains for hours on end. He tends to keep to himself afterwards however, and will sometimes refuse to talk about things. He actually wishes to start a special lineage of his own, with a special family name which would be 'Fusion', his second name.
