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.

Riptidefin is an unusually large size for a Deep Sea dragon and is rarely seen by any dragon. Riptidefin is also at a very old age and is considered ancient by most dragons. Any dragons claiming to have seen Riptidefin are usually not believed and classified as liars, yet some have noticed the dim glow of his scales in the distance deep under the surface of the ocean. Riptidefin has no known children, yet no dragon is sure.
