Undine Dragons are named for the water spirits with which they share territory. They have close relationships with these spirits, and are able to communicate with them. In exchange for protection and respect of their mutual freshwater homes, laid eggs are often protected by a blessing. This blessing stays with the dragon into adulthood, and with it they gain potent magical abilities. Sometimes when an Undine Dragon becomes very upset, the ground at their feet may frost over or begin to steam. They have also been observed to manipulate water directly, rerouting raindrops or creating puddles from groundwater. Undine Dragons always live near forest pools, streams, or waterfalls. Both genders take equal part in the raising of young and are very good parents—though they may not remain mated after the offspring are grown.

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.

Kuren lives in a small lake that sits between two castle fortresses, both summer homes for royalty of two different kingdoms. Over the years, he's seen plenty of noblewomen throw handkerchiefs, scarves, and ribbons into the water, hoping that a kind and handsome suitor in the other castle will find the favor and return it to them. This doesn't happen often enough that Kuren feels like he needs to ask them to stop, but all the same Kuren will intercept any of the love tokens thrown by maidens he regards as disingenuous or otherwise undeserving. Usually he simply leaves the "returned" items on the shoreline, but sometimes he will keep them for his own hoard if he likes the embroidery or patterning enough.
