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.

Olaf lives with a rookery of fellow Coastals on his Clan's southern Coast. He is a sassy and confident creature who is near the top of the Rookery's ranking, though they have no official leader or hierarchy. He tends to be chatty and flirtatious and doesn't have very loyal friends, so the crowd he hangs around with changes frequently; in short he is a generic, gossip-loving sassy pants. Remarkably he is quite independent, hunting for himself and with quite impressive fishing skills, which he loves to boast about. Despite these quirks he isn't too unpleasant to be around, and he has his ethics that he'll fiercely defend if it comes down to it.
