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.

Octa is a playful and friendly spirit whose best friend is another Nocturne named Vadim. He lives in a den within his Clan's Main Cavern and has a habit of eating bats as snacks, but he also cares about them oddly enough and often lays out things to attract insects for the bats to eat. He acts very joyous and carefree, except when someone threatens his bats. During Clan meetings, he can often be seen clinging to the ceiling somewhere with Vadim and looking down at all the hubbub below.
