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.

Althenor has a bit of a mischievous streak. He loves using his camouflage to hide in the waves and lunge out at unsuspecting beach combers with a loud snap of his jaws. He'd never really bite unless he felt threatened, as his favorite foods are starfish and croakers. Always on the go, it's hard to pin Althenor down for any sort of conversation. He will sometimes give unexpected boosts to good swimmers, for he appreciates grace and athleticism in the water.
