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.

Cold Sea and her sister, Glacial, were named because of their attraction to arctic and antarctic waters. Unlike most of their kind, they hunted best in near freezing water. She was named cold because she swam all the way to the polar regions to look after her sister.

Cold was the quieter of the two of them, and didn't make contact with humans as often. She lived atop a mountain peak in the south pole, and had collected several precious stones to make her place look nice. There was a river going down the mountain so whenever she needed to hunt, she had a shortcut.

She was at her house after the tragic death of their mother, and was putting some things down to make her place look even better. She loved crystals, but she had often wondered what it was like beyond the atmosphere.
