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.

Although most dragons of Thoiris would consider Eva's lineage perfectly normal, perhaps even something to be proud of, her unfortunate heritage has caused her many problems. The clan's other Lumina dragons have taken their desire for purity even further, accepting only purebred Luminas in their community. Because of this, Eva has always been frowned upon and shunned among her own kind, for the sole reason of her blood being "tainted". She finds this unfair and actively fights against their prejudice, claiming that nobody should be left out for something they have no control over.
