Skywing Dragons spend most of their lives flying in the air. They hunt from the air, diving at prey from above, and land only to rest. They are some of the fastest fliers, capable of extremely high speeds. The webbing at the end of the tail acts as a rudder, allowing them to easily change direction during flight.

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.

While teleportation is the mainstream form of cargo transportation among dragons after its spread, there are still areas where teleportation is not an option, such as heavily-fortified cities and castles with anti-teleportation magic in effect under the fear of surprise attacks, which is where couriers like Skytrain save the day.

For the particular clan that he belongs to, Skytrain is the only dedicated courier, and is well-known for his reliable services, with the distinction of completing his job no matter how dangerous it is. And after visiting so many places during his service, he has naturally earned nicknames from locals like Dakota and Gooney Bird, and many more that he could not remember himself.
