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.

Orion is a bold and playful. He was the first of the StarHearts to grow up and considers himself somewhat of an authority figure, although he is more like the big brother who gets everyone else in trouble. He loves to fly at night more than to simply watch the sky, finding the heavens even more beautiful when he is tumbling and wheeling around underneath them. Orion has tried to fly all the way into outer space before but hasn't gotten very far, turning back when he gets tired or bored of just flying up.
