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.

Lorenso brazilia is boastful, confident, quirky, charming and peaceful, but he can be a huge loudmouth. Lorenso likes to show off his natural aerial acrobatics and is a very talented flyer. Lorenso's agility makes him great fun to watch. He became a nocturnal dragon because he likes to fly during starry nights. He really likes the light that passes through his thin wings during those nights and the effects that go along with it. Lorenso also dreams of seeing the northern lights one day. Lorenso flies most of the time in very high altitudes to avoid enemies and other dragons that flock the sky. He can only fly for a short period of time in high altitudes because of the limited breathing air. Confronted up close Lorenso is very large that it would even intimidate others. He also likes to teach winged hatchlings to fly more gracefully and to let them see that their wings can be used more than only for transportation. Lorenso's talent in flying allowed him to fly through dangerous storms.
