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.

The deep sea is more dangerous than land in many ways, but Celere adapted easily. One of the largest dragons of the deep, she can fight off giant squid and other predatory dragons with a single flipper. Though incredibly powerful, Celere cannot survive long outside the ocean, and yearns to see the forests she has heard so much about. She has only two links to the world beyond the sea: Seneca Stripesong, whose life she saved long ago and the son she had by him, Tyr Stripesong, whom she loves dearly. When Tyr visits, the two often trade stories of the adventures they have had in the wild forests and the deep sea.
