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.

Krisztofer collects crab remains and decorates his cave and welcome post with the empty carapace and legs. Whenever he decides to find a new place to stay, he takes his food, jewels, and potion materials along with him, only leaving the decorations behind. If the lake or waterway he makes his new home has no crabs, then the cave and post remain undecorated. Kris is grouchy, but the one guaranteed way to please him is to compliment his decor or bring him crab parts. If someone does either in February, regardless of species, he'll try to court them.
