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.

As a hatchling, young Coco was separated from his parents. He remembered his brilliant silvery mother long after this, even when he started to settle in with the kind clan that took him in, and attempted something ambitious like no Nebula before: every night, he spread his wings wide and intently looked to the moon, hoping to capture the same lustrous gleam of silver on his skin. While haphazard swirls of green nebulas cover most of his wings at random, he did succeed- on his back, stretching onto the base of his wings, he proudly displays a shining circle of silver scales. He's a bit offbeat, and not particularly social, but he is still friendly, carefree, and willing to converse.
