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 dragon is infamously known for sneaking inside the homes of families at night while carrying a bag of ordinary sand in its mouth.

Once inside this dragon makes its way to the rooms of children where it chucks sand in their sleeping faces while yelling "SWEET DREAMS!, GOODNIGHT!, SWEET DREAMS!"

The dragon then makes its escape either through the window or through the way it snuck in before anyone can make sense of what is actually happening.
