Coastal Waverunners spend most of their time skimming the waves along the coast, snatching up their prey from the shallow waters. They have developed markings along the leading edges of their body that help disguise them as breaking waves. When they are not hunting, they enjoy playing among sand-dunes and shallow tide-pools. These dragons live in small but noisy rookeries. Some stories say Waverunners can fly for days on end without landing.

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.

Coureuse loves windsurfing. It isn't easy to catch fish when on a board borrowed from the kitchens, but she manages somehow. Never mind the shallow waters—she leaves them for the shallow water dragons; she likes the deeps where she can bounce happily off the waves before they break all over her. Though that does mean her camouflage is rather wasted. She can fly for days—but still would rather skim the ocean; flying is limiting and samey, she says. She holes up in the cave with Le Sable and they discuss adding to their rookery with a little or two—but so far have agreed that they prefer it with just the two of them—none of the other dragons wants to put up with the noise of them chattering endlessly at each other.

She does like the odd laverbread, from Wales. But it isn't common among the local seaweeds.
