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.

Alierei was found as an egg sitting away from the others. As she matured she tended to keep to herself but loves human company. Her wings imitate part of the Orion Nebula and she often entertains the young dragons by imitating shooting stars across her wings. She is a strong warrior and is a very fast flyer. She has a small circle-shaped birth mark on her nose that stands out on her face, she is a bit self conscious about it. She doesn't need much sleep and shifts from being nocturnal to sleeping at night. She doesn't hunt as much as other members in her adopted family and is more likely to stand guard.
