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.

The Castle Master had randomly stumbled upon the pale blue egg on a rough trek through the desert one night, its surface reflecting the moon's shine. The hatchling inside was quiet and almost scrawny in size, but that didn't seem to have affected her. Luina is one of the most gentle dragons in the castle. Though naturally she's quiet, she is friendly and sociable enough. Even the Seragammas are partial to the Moonstone dragon, never once being seen to have a quarrel with her. At night, when the moon shines brightest, she can be seen walking down the corridors, her tail stone luminescent with the moon's rays. New hatchlings brought to the castle have been known to try and stay up on clear nights, hoping to catch a glimpse of Luina before they can no longer stand being awake.
