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.

Two Tailed Terror is Tea Leaf's mate. She is regarded as the most agile of the dragons in her area, and possibly the most graceful. Two Tailed Terror enjoys hunting, as it is a time for her to show off. She can be a bit of a wimp occasionally, but otherwise she is always raring to go. Two Tailed Terror's name is often mispronounced, as it is a bit of a tongue twister. Despite being possibly the most energetic dragon, she likes nothing more than letting others do the dirty work for her. Although she disagrees with having slaves, she secretly wishes she was more like Sundown and could threaten some into acting as her servants.
