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.

Hoag has a very distinctive pattern on his wings. After watching a certain part of the snake constellation for a very long time as a hatchling, he now shows various bright yellow spots surrounded by blue rings within his pattern. None of the other dragons of his clan had ever spotted that object in the night sky before him, so they named it after Hoag.

He is of course very proud of that fact and boasts about it to every dragoness he encounters, and at least the Nebula ones are thoroughly impressed.
