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.

This Green Nebula dragon has heard his given name so little that he has forgotten it altogether. Many insist that his name sounded like an anatomical body part, but none can specify which one. Even EG, the keeper of the Cave, has forgotten his original name. He has jokingly started referring to himself as Never Again Mentioned.

During his leisure time, he travels to places of his past. He visits old mates, ancestors, the nesting area where he was lain, yet no one has been able to relay his name so far. However, Never Again Mentioned does not necessarily view his situation as a bad one. He has also been gradually searching for a new name to take in place of his old one. He guesses that this predicament will allow him to take a better name than before.
