Moonstone Dragons are named after the orb on their tails, which resembles the gem of the same name. They are nocturnal and gather energy through the absorption of moonlight with their orbs. They seem to glow with a lunar light and are a very gentle breed, feeding off of plants and the moons’ power.

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.

Beneath the golden moonlight of Aurax, Ceruleanmoon appears to be a typical, kind and gentle Moonstone dragon. He never bothers anyone, quietly going about his routine of gathering plants and storing moonlight. However as Aurax's light begins to wane and the blue light of Cirion becomes dominant he seems to change with it, traveling away from the cave under suspicious circumstances while one or two others wind up missing as well. These individuals usually turn up when Aurax begins to brighten once more, with no memories of what happened while they were gone and no idea who was behind their absence. Ceruleanmoon has been questioned about these events, but his alibi is always air-tight.
