Mutamore Dragons are a mostly solitary breed, preferring to be alone in the waterways of the world for most of the year. However, when winter begins to wane, these normally grouchy dragons undergo a massive personality shift and become excessively chipper and incredibly social with the solitary focus of pairing up themselves—and other—dragons. They become such annoyingly happy and persistent match-makers that other dragons have been known to pretend to be pairs when one is in the area, just to avoid the attentions of the Mutamore Dragons. This temporary pairing up tends to lead otherwise disinterested dragons into a better appreciation of one another, resulting in lasting relationships. This has given the Mutamores the false reputation of being good at match-making.

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.

Unlike his on-again, off-again partner, who is almost always unhappy about something and therefore predictable, any little thing can make Premature Confetti ecstatic or livid or morose. It's a wonder those two get along at all. He celebrates happy events by throwing little pieces of paper and eggshells. Whenever he approaches a human town, an alarm is sounded. His mood swings make him dangerous, and the bits he hurls can be a health hazard, and they need to be cleaned up afterward.
