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.

Racheloko has the deepest home in the entire cave, and it's filled with seawater. She hates being around other people that aren't in the clan. She fell for a shallow water dragon out in the wild as hatchling. The hatchling was killed in her parents' clan's raid of his clan. Racheloko was filled with rage ever since. She sits at the bottom of his extensive tunnel home and ponders what would happen if the Shallow Water dragon had lived. She's of the lonely nature and usually makes impressions on first appearance.
