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.

Messiera is so named because she observes and displays the Messier 33 or Triangulum galaxy. She has quite the eye for color and beauty and paints upon canvas, along with many other materials. For certain shades, she uses the powder of her own shed scales as pigment. She often paints portraits of both dragons and humans, and has repeatedly asked Viorett to pose for her, as she finds the colors and patterns of his wings both beautiful and challenging.
