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.

Crocodylus acinosus, along with his brother C. similis, were first gathered as eggs straight from an unattended nest by an amateur herpetologist. As a result of said amateurism, the brothers were completely misnamed—at least, placed in the wrong genus. They were eventually released once their abrasive personalities proved too much trouble to handle, and long since parted ways.

C. acinosus lives in a broad lake in the middle of the densest forest he could find. Within the first year of him moving there, word spread fast to go to every possible length to stay away from that place once the weather began to warm—not because its infamous inhabitant was out to hunt everything he could, but because he'd persistently try to pair up both himself and other dragons. Once C. acinosus noticed the decline in local activity, he developed the habit of wandering far from the lake in search of others—thus missing the subsequent hustle of dragons gathering what they could before he returned.
