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.

This dragon is strong and intelligent. He finds life easy and roams the bottoms of the seas. He shares advice even though he's only recently grown. Others think he has the wisdom of a 300 year old dragon. Darkened Mystery never worries about falling in love but loves being with friends. Often playful, he even plays with the young every now and then telling them stories of the deep sea as they listen in awe. He's great at making friends even with humans. Also, he can be out of water for more than 12 hours but prefers to be in the sea before then. He's never experienced the mating session on the upper part of the sea and doesn't think he will for a long time.
