Lumina Dragons received their names from their highly reflective scales, which—at times—seem to glow. They are vain, always strutting about and preening incessantly; if one of their scales has so much as a scratch or a defect, they’ll remove it. Luckily, their scales grow back quickly, and each new growth is more beautiful than the last. These narcissistic dragons live in small groups and prefer to surround themselves with beauty. The females guard their territory and eggs while the males search for vegetation to eat.

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.

As is usually expected by his breed, Vanier is one of the vainest dragons inside the castle. Even a single scratch on his beautiful scales will cause him much distress, and he'll remove the flawed scale at once. Often the younger hatchlings will pick these up and ogle at its surface, not so unforgiving of a simple scratch. His vanity has caused much dispute between him and those in authority, as Vanier will decline doing chores that could harm his looks. It's gotten so bad that he will stay inside the castle on stormy days so as to keep mud from disgracing his pristine scales. Once, the Royal Blue, Braxe, got so fed up with him that he raked his claws down one side of the Lumina, marring his scales. Vanier was horrified, and still has a deep hatred for the blue dragon.
