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.

This Coastal Waverunner is very playful and nosy. He always seems to disrupt the fishermen and other aquatic dragons when they are trying to hunt, and often finds himself on the wrong end of a spear. His name, Lemero, is derived from the French words "le mer," which means "the sea." He certainly spends enough time in the water to earn the moniker, and some even doubt the dragon is able to fly. No man or dragon has seen him attempt it, so it may be true.
