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.

Fery Tayl (who responds better to Fery) is a big softie, normally found by the eggs her owner has collected and keeping them safe from any predators. She completely respects her owner's decision to abandon eggs and will not try resist, though she deeply wishes they were kept safe in her own hands. When an egg is killed, Fery grieves silently but carries on life very positively.

Fery is incredibly kind and has rarely ever been seen in violent action. Due to this nature, she relies on her fellow friends to keep her safe. But if need be, she will attack under threat.
