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.

Sylladices is the assistant to Fetch Modi. He has an assistant called Captchalogue Deck, who has an "assistant" called Captchalogue Cards. His job is to get items from Captchalogue Deck back to Fetch Modi, so that Modi can return all the items that Captchalogue Cards stole from other dragons.

But since he's a Lumina dragon, this can often be a problem.

He refuses to go out and hunt for items from Captchalogue Cards himself, instead relying on Captchalogue Deck to do it, since it'll "get his scales dirty." Once he actually does get items from Captchalogue Deck, who had painstakingly hunted them back for him, they'll usually be stored away in the depths of his cave for a long time while he worries about female dragons and how he looks like.

It can take years for an item to transfer up the chain from him to Fetch Modi. His hoard is huge too.

But still not as large as Captchalogue Cards's.
