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.

Castlemaker was named for the many sand castles she made on the beach as a hatchling. As an adult, Castlemaker is a very maternal dragon, and spends most of her time caring for the eggs and hatchlings of the ever-growing Eclipse Clan. Castlemaker herself was raised by a human woman who rescued her and several other dragons who were found as abandoned eggs; the Eclipse Clan was founded by Castlemaker and her adopted siblings to expand upon the good works of their human mother by rescuing abandoned eggs (and the occasional hatchling) and raising them as members of a large and varied yet close-knit adoptive family.
