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.

Aquaslash is a Waverunner that lives on a sandy beach. He is the leader of his Waverunner pack, which has six dragons in it. Aquaslash mostly hunts fish, but sometimes he brings down a whole shark with the help of another Waverunner from his pack. If threatened, Aquaslash's pack is known to slap enemies with their tails, sometimes leaving a deep cut due to the barb at the end.
