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.

"You are Just Wonderful," said her caretakers. And so she became known as Just Wonderful. In her youth, her favorite space-spot to observe was a cloud of dust and numerous stars so far away that they've redshifted even to her eyes. This is an unusual choice for a nebula, but for some reason, the caretakers were extremely pleased with her nonetheless. As an adolescent, Just Wonderful decided she wouldn't ever seek a nebula mate. Instead, she began seeing a xenowyrm, this dreamy young fellow with wild ideas about space and honey and dreams. To her almost-disappointment, the caretakers again were very happy with her life choices. No matter what she did while under their care, no matter how strange or questionable her behavior, they let her do it. To this day, Just Wonderful still wonders what's on their minds.
