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.

StarryNebulaSky is an exciting Nebula Dragon. He spends his nights out "adventuring" as he calls it. He likes to get into fights with wild dragons or large predatory animals. He isn't allowed to get into fights with gangs of young humans from the nearby villages anymore, because of a truce between the Dragon Council of StarryNebulaSky's cave and the human leaders. Instead, both groups have created a tournament pitting humans against dragons in a non-bloody sport.
