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.

Head-over-heels in love with MidnightStar, InfiniteStar tries everything to get her attention. Although these two Nebula dragons are mates, InfiniteStar's mate spends more time with her adopted older sister, FallenWish, than with him. InfiniteStar can get a bit jealous at times, but his jealousy will vanish as soon as he sees MidnightStar's joyful face when she's with FallenWish. At night, InfiniteStar would glide through the starry night sky with MidnightStar. What he doesn't know is that MidnightStar is possessive of him and is willing to chase off any female that becomes more than just friends.
