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.

Celestae is very fortunate to have found her nebula. It is exquisite judging by the looks of her. She has three stars on her forehead. Deep neon blue, dark red and a gold one (in descending order of size). The rest of her is covered in a variety of other colours in different degrees. She is fond of sparkles and shiny star trinkets. She loves skylights and has a large dome shaped one as her room's roof so that she can have sweet dreams. As a result her room is covered in sparkles.
