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.

Media Snarker is a general contractor, apparently the one in Abdulov and Co. most concerned about cleanliness. He considers himself "sort of middling" compared to his coworkers, yet he seems fairly popular. His neighbors figure he must meet a lot of people and make friends in different places because often he has guests over at his home. Since he resides in the innermost den of the cave system, he and his guests pass the other units on their way to his. Whenever someone knocks on the wall asking what's happening, Media Snarker comes out and informs the neighbor that he and his friend are in a session devoted to disinterested discussion about the details of a construction job or the future of his company. If the neighbor complains about the noise level, he insists that their discussion has gotten lively and there's nothing to be concerned about.
