Carina Dragons, though a rare sight, are quite brilliant to behold. Typically gentle, they abhor violence and have developed a rather unique method of camouflage to avoid it: their wings and bodies blend into the night sky while the cobalt flames that adorn their bodies burn brightly, making them appear to be shooting stars when they fly. Their fire also wards off predators and shields them from unwanted brawls. However, despite this enmity toward bloodshed, Carinae can become dangerous when faced with peril, especially if their young are in jeopardy. Legends speak of young Carina Dragons consuming entire constellations, which then become emblazoned on their wings.

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.

"Mio Mio Mio"—she's told it means "Mine Mine Mine" in a language she doesn't know. It fits her, at least when she was a child: she would point to things and proclaim "Mine!", including the sky. When her parents asked what that meant, she would affirm, yes, the sky. All of it. The stars and dust and countless heavenly bodies that her mother described to her are all Mio's, according to Mio. Like most adults, a lot of behaviors she had as a child she considers immature or embarrassing, but not her "ownership" of outer space and its non-Valkemare contents. She still likes to wave at it in a facetiously dramatic manner and call it hers. It isn't as if anyone else can own space, either.
