Nocturne Dragons are a strange breed. Whenever light strikes their bodies, they are frozen in whatever position they were in. This leaves them vulnerable and they rely on camouflage to keep themselves safe. They are often mistaken for statues when in this frozen state, but Nocturne dragons do not actually turn into stone. Rather, they merely idle until the sun goes down. At night, these dragons come to life, proving themselves to be powerful fliers, although little else is known about their true behavior.

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.

Wix Han is the second of the nocturnal couple living in the Cliffshore Sanctuary. It was originally her clever idea to use the castle's architecture to disguise as statues, which worked perfectly. Initially, when a human came, she contemplated leaving, but soon enough it turned out that coexistence with him was favorable enough, as the person gathered an unusual society of various dragon breeds around himself that somehow managed to support and sustain each other.
