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.

Sixtrah is one of the special dragons born to EG's Cave with a birthmark giving him his name. The Magi of EG's Cave told him that his name had a special meaning and that he had a special purpose in this world.

But unlike the other dragons named by the so-called dragon gods, he has yet to find his purpose. He does not understand what his special name even means.

Because he does not understand his true purpose, he participates in volunteer work throughout EG's Cave. Each week, he volunteers at the Heal Sector with the Whites and also participates as a volunteer soldier with the Blacks. He hopes that a good deed or two will help him to realize his purpose.
