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.

Galactic Interface is a tech-savvy dragon with great interest in inventions. His interests seem to steer away from those of ordinary dragons, and he often enjoys pursuits of knowledge and will sketch complicated diagrams--often ones of potential spacecrafts, if not entirely accurate--on the walls of his cave, though of course no one else believes such a thing could ever work. His dream to one day visit the nebula which he has changed his scales to match has driven him to an unusual obsession with the idea of intergalactic travel; being something completely unthought of in his era, many believe him to be deranged, though he might just be a genius in a madman's disguise.
