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 has never been known for wisdom. In fact, he has done so many foolhardy things that most dragons just call him Fool. In his part of the deep, it is not uncommon to hear another dragon's telepathy resounding through the water, declaring: "Why Fool, Why!"; and even without being close enough to see him, it is obvious that he did something without thinking—and nine times out of ten, has gotten himself hurt in the process. Many speculate that eventually he will lead to his own demise.
