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.

Dark as the Stars, like many nebula dragons, enjoys stargazing. He will sit atop the same tall boulder ever night, watching the sky.

Although he is generally quiet, Dark as the Stars is not unsociable. He will talk with anyone who tries to strike up a conversation, so long as it's not while he is stargazing. He believes that nighttime is a time for him to be alone with his thoughts and the heavens, only allowing Taline to approach out of courtesy and love for her. Anyone else who tries to disturb his reflections will be politely asked to leave, or ignored.

He dislikes youngsters, finding them noisy and irritating, but has a high respect for authority and so obeys Salaesha's wish that he leave the hatchlings be. Because of this respect, he would probably reluctantly let Salaesha approach him while stargazing if she tried, but so far she has left him to it.
