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.

When Oceanhaze came out of the water to mate, he didn't expect to be doing it with another dragon breed, especially not one as opposite to himself as Firestonetail. Once his family found out what he had done they were not happy, though they forgave him. He often wonders what happened to his egg since it was abandoned. Although he hates it, he sometimes surfaces the water by the shore to see if he can spot Firestonetail or his possible egg.
