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.
Frederic - as most of his peers call him - would love to feel as important as Hoag, so he claims to be the first dragon EVER to have discovered the galaxy now showing on his wings. He wants the others to name the whole pattern in the sky after him.
But of course he has picked out a bright object many a Nebula has watched before him, probably one of the most well-known star patterns among his kind, so the others ignore Frederic and continue to just call it the "Big Cloud" without any reference to him at all.
