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.

As winter wanes, this dragon likes to sneak up on solitary dragons, shout "I know just the mate for you!" and drag them by whatever limb is closest to him to the next solitary dragon he sees. He presents the dragons to each other and then stares expectantly at them until they greet one another nicely.

The dragons Shuvemtoogettyr introduces to one another are typically very embarrassed and try to flee the scene, but he will not have it. If the dragons try to leave, he grabs them by a limb and drags them back to their 'chosen' mate.

Some dragons have learned that this is an easy way to get paired up with a mate that will have no long-term expectations of them. They intentionally wander into Shuvemtoogettyr's territory and greet their new 'mate' with genuinely pleased anticipation. As a result of the casual matings, Shuvemtoogettyr is very proud of the number of successful matches he has made.
