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.

There is a dragon named Marena that frequently rises here. The locals say that for the most part Marena prefers to keep to herself. Marena prefers to watch what is happening instead and is often joined by a skywing dragon named Linaeus flurry. She is very well known for being sarcastic, quite a wonder considering she doesn't speak very often. There is also a rumor that Linaeus is Marena's mate and they've had a daughter. But when she was asked about this she neither denied nor confirmed this. Most people prefer to think that this is just a rumor as the differences between the species would make this very unlikely.
