Nebula Dragons are nocturnal creatures. With the best eyesight to be found, they are often seen staring into space. Each dragon tends to observe a particular nebula and will eventually change their colors and patterns to match it. As the nebula changes over time, the dragon changes with it. The more intricate the design of the nebula, the better chance an individual has of attracting a mate. It is said that the markings on no two Nebula Dragons will be exactly the same.

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.

Galaxy Canopy loves to perch on the foliage of the dense forest trees as the night moon glimmers overhead. He favors the Orion nebula, because of its relation to the mythological figure, Orion. Orion was known for his ability to hunt, so of course he spent most of his time in the greenery of the forest that Galaxy Canopy loves so much. The Orion nebula is located just beyond his constellation, which may be why Canopy loves his selection of nebula so passionately. He is a shy dragon, spending most of his time alone or with his mate Galaxy Trail on the forest, while the rest of the Galaxy Paint dragons tend to frolic in the mountains of the nebula island of DragonPassion's scroll. However, occasionally he comes out of his shell and visits the rest of the "community" planted in the center of the island.
