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.

A legendary dragon of NeverWinter Myth, Crisemos lives in Origoth, south of the city of NeverWinter. She lives in the star observatory in Aquaria. She has the appearance of a normal Wyvern until moonlight falls on her and she takes the appearance of a nebula dragon. She was a one of the first dragons to enter Origoth. Her power can help teach other humans and dragons about astronomy.
