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.

Ronan is a peaceful and solitary dragon who loves stargazing. Night in, night out he will do nothing but stare into the sky as if he is reading a book.

Ronan's strange behaviour stirs up rumours that he can read the future. Several people tried to confirm this rumour, but they eventually gave up. Ronan never gave them a clear answer, although he also never grew angry. He greeted every presence with a polite nod and gave a curt silence for every question.

Other dragons tend to pay him a visit when they are in trouble and pour out their hearts. He knows their deepest secrets, yet he never shares their story to anyone else. Talking to Ronan is much like sealing something in a secure box; which could be the main reason why he is called 'Ronan', in other words 'Little Seal' in Irish.
