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.

Oriona is a being of courage, valor, and triumph. She takes after both of her parents, snatching up her father's bravery and stealing her mother's boldness. The fiery red patterns on her wings create flames in the night that often terrify dragons who are out for a stroll, but also generate a gentle warmth comparable to a hearth when she wraps them around those she loves.

While focusing mainly on performing heroic duties in the cave, Oriona will occasionally stray when something else piques her interest, such as a particularly powerful air current that is strong enough to carry her far away or a flock of strange birds flying overhead.
