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.

Due to his flying speed and stamina, Tameiki is the family night tracker. If a member of the clan goes missing at night, Tameiki is nearly always the first to be notified and the first to leave the caves to search for them. The nocturnal hatchlings are taught to recognize the sound of his roar and to remain in place when they hear it, unless they are being pursued by predators. Though he usually remains asleep during the daytime, Tameiki will sometimes fly through the deeper clan caves during the late evening, practicing his aerial maneuverability and preparing for the next rescue.
