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.

Isis, as she likes to be called, is an ever-vigilent, extremely haughty Swallowtail. Working for the Republicators as a sentinel, she keeps a close eye on the Separator Border, making absolutely sure that none of them cross into Republicator territory.

Chell and Isis are fast friends, mainly because they are the only two Swallows in the Wisdom Territories. As Chell is mute and brain damaged from being frozen too long, Isis acts as her overly-bossy mouth, often telling others exactly what the test subject means when she jumps.

Because Isis is relatively irksome--she enjoys telling others what to do, when to do it, and exactly how to do it--the Jeedi Order made sure she was places somewhere where the only things she could boss around were plants.
