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.

Aurum is a huge fan of the fall season. He loves the warm colours of the leaves, the 'just-warm enough' weather, and even enjoys the stormy winds that come along with the change of the seasons. While nocturnal for most of the year, he makes a point of staying up for a couple of days each autumn to wallow in the warm colours and the last warming rays of the sun before snow covers up everything and the yuletide dragons get busy.
