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.

As one of the oldest dragons in his group (those who follow a human known as 'fog shadow'), Endless Galaxies enjoys a quasi-lieutenancy under his leader, 2000 Years. Close to one another in age, 2000 Years—a storm dragon—and Endless Galaxies also share an avid interest in the skies, although Endless Galaxies is more inclined to enjoy the aether as it is, rather than the idea manipulating it; indeed, Endless Galaxies has occasionally expressed minor vexation with 2000 Years for some the latter's meddlings with the weather.<br/>In general, however, Endless Galaxies is quite non-confrontational. His temper is fairly mild, but when pushed beyond the breaking point, he typically takes off into the great welkin, disappearing for several days at a time (once, even, for nearly a month); he returns from these sojourns greatly mollified.
