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.

Waterstream wasn't named until she matured—like all of the other hatchlings in her tribe. When she was named, she was named because of her love to swim in rushing streams. Waterstream spends more time with her mom Valilia—mainly because she doesn't get Herephyre's love of sitting in volcano craters. Waterstream doesn't even know what she's going to do with her life—she's just going to swim in the rivers and see if someone catches her eye.
