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.

Cheese Meta enjoys cheese, which the local spirits and nearly all of the other dragons take offense to, since it's odd to not object to eating solidified mammalian... wet stuff. She keeps a list of personal cheese rankings and documents different types of cheeses during her spare time, and she's had more and more spare time lately as she loses clients over her demeanor and the cheesy smell. The "dragons" made of enchanted cheese used to be able to safely inhabit an area populated by dragons, but ever since Cheese Meta gobbled one down because it was "a variety of mozzarella seldom exported out of Bee-sontay", they've stopped walking around so brazenly. The only dragon who doesn't mind the cheese fondness is Cheese Meta's mate, who is so polite and nice that even if he did, he wouldn't say so.
