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.

DeepOceanBlues is a Deep Sea Dragon who is often alone. Other dragons think that she wants her space, and don't bother her; but inside she longs for friends and conversation. So she spends a lot of time near a certain cave on the sea bed, and composes dark, sad songs. Songs that she only shares with the odd glowing creatures on the ocean floor and her mate OceanFrills. She only sees him about once a month due to him needing to breath air and her instinctual dislike of the ocean surface and the bright Sun. It takes a lot of courage for DeepOceanBlues to swim up to the surface and meet with OceanFrills, braving the harsh sunset and the choppy waves. But she feels so happy when she spends time with him, that she tries to confront her fears as often as she can.
