Deep Sea Dragons, as their name suggests, spend most of their time in the darkest depths of the sea. They have a bioluminescent dorsal spine that serves to attract prey and communicate with their own kind. As with many deep sea animals, they generally eat whatever they can manage to bait. They rarely leave the ocean floor, surfacing only during breeding season. When they do choose to travel to the shallower depths, they avoid bright lights and will only come up far away from shore.

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.

Sarumi, a dragon that was born with the water, had a very peaceful life. As an egg, a young-adult female Waverunner found his egg. She wanted to help, but didn't know how. So, she took the egg to the Uncita clan. From then on, the Uncitaians raised him peacefully. However, one day he was swimming in the lake, (he was an adult) a flock of wild Water dragons were bullying him. Sarumi swam away frightened. From then on, Sarumi would never go out in the eastern waters. Then once he tried the southern waters. That's where he lives, the closest beach to the Uncita clan territory. Sarumi is a brave, quiet, and gentle sea creature.
