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.

Drewll, being a deep sea dragon, loves the ocean floor. She loves to play by herself, disturbing large crabs, swimming in circles and so on. She also serves a different purpose. Many enemies attack from below the waves. The cave that hatched and raised her told her of this. She is 10 feet longer and taller then a normal deep sea dragon, and her roar can be heard above waves. She doesn't like to fight, though, but the roar is enough to scare away most.
