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.

Aeoryth, like his title, is very withdrawn from the others. His wings sparkle and shimmer constantly, as all Nebula dragons' do, but he spends his time indoors writing poems and singing to the younger dragons instead of showing off like his brother, Emereth. He does, however, have a secret passion for flying that he prefers others not to know, so the very few times the cave goes out on a mass hunting trip, he stays behind to fly with his sisters, Miann and Sorren.
