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.

Golondrina is a lovely and gentle dragon. She loves flying, for it is like dancing in the air to her, even if she can't hear the soft whistle of the wind as she was born deaf. This does not stops her from being a happy dragon, though. Some others have learned to communicate with her by signals like head or wings movements, and there's no one who can say they hate her. It is often said that her only sin EVER was to become Zorzal's mate... for he is so annoying to others that they are patient with him on this cute lady's behalf.
