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.

Unlike her more rebellious sister, Crush, Nibbles always loved the color blue and solemnly swore to imprint on a nebula of matching color. Thus did she uphold the family tradition, complete with obtaining an adorable sunsong husband, agreeing City of Owls is the best bard ever, and learning how to crush a watermelon with nothing but her thighs. While she's thus an extremely respectable member of her family, no one knows her dark secret; she finds nebulae impossibly delicious to look at, and often nibbles on her kin's wings when they're asleep, giggling dreamily all the while.
