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.

Herodotus considers himself the faithful guardian soldier of Damian's cave. When morning comes, he always sits in the same pose and same location just outside the entrance, allowing his statued form to keep a watchful eye on the surrounding area. Despite this, he doesn't have the ability to do anything to protect himself or the cave in this form, so the actual protective responsibilities usually fall to Melissa, the mother Magi dragon. At night, he ascends to great heights to watch the cave from above.
