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.

Lugion loves waiting for the sun to set over the horizon and waits for people to come watch the sea at night. Once they stare enough, Lugion becomes one with the waves and moves backward and forward in the water. After a few minutes he starts rising and making an impression that the waves are getting bigger. While a little startled, humans start going backwards from the sea. Of course Lugion doesn't stay at the sea; he gets closer to the humans, as if a tidal wave is trying to get the humans. When humans start screaming or fall to the ground, Lugion flies very fast and... flies over them. People again see a not so wavy sea and not all understand that they have been fooled. Only at night Lugion is not spotted for a long time by weak human eyes, so he can play this prank only then.
