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.

Although a Deep Sea Dragon, D1AN1A spends a larger amount of time near the surface and the coast than is usual for her breed. The home of the clan to whom she is so attached is a series of caves located on various levels on a cliff face and the bottom-most of these caves is one of her favorite places to be. D1AN1A loves to spend her free time diving and hunting, but the only place she feels safe resting is her cave. This is due to her being smaller than most deep sea dragons, which means she feels vulnerable living in the deep sea far away from her clan.

D1AN1A is a very sociable dragon and is friends with everyone in the clan, but her particular friends are 5APH1RA, SABR1EL and HY0UR1NMARU with whom she shares the lower caves.
