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.

Because Ocean's Breath (Ocean) has lived in the darkest depths of the ocean with little contact to other dragons, he is shy. He rarely surfaces, even for mating season, because of his awkward socializing skills. Ocean's luminate spine keeps him entertained while he is swimming in darkness, and he enjoys making colorful displays for his own amusement.

One good skill all fishermen need is patience, and that is one reason why Ocean is such a skilled hunter—even though he lives in a place with meager meals. Ocean takes his time and instead of constantly flapping his fins, he usually just lets the ocean carry him so he does not waste any energy.
