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.

NeelSagara is a Deep sea dragon whose egg was found by Pearlwave the Water while she was searching for gems in an undersea shipwreck. No one has any idea what the egg was doing there, but it was gladly adopted by the owner. The hatchling was placed in the ocean, where she made her way back to the shipwreck and wrecked it some more. Having got that out of her system she made herself a pretty nest deep under the sea and often visited her family. Because her coloring made her almost invisible underwater, her owner named her NeelSagara, which means blue sea. She uses this coloring to blend in with her surroundings and destroy any ships that travel over her territory. No one, including NeelSagara, is sure of the exact reason of her violent hatred of ships, but it is assumed that her egg went through some trauma because of the ship it was found in. Other than her dislike of ships, Neelsagara is a cheerful dragon who loves taking others for undersea rides on her back.
