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.
Queen Rosalina isn't as vain as most other dragons of her species, in fact she enjoys looking at all the differences between dragons and likes telling them how each one is unique and that they should cherish that uniqueness, instead of wishing that they had anothers unique trait or ability.
