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.

Every year, this deep sea gets season tickets to all the stickwaterball tournaments. He is incredibly loud for a dragon whose kind are not known for vocalisations, and his cry of dismay when the team he is rooting for misses a point or lets the other team steal the ball is a staple in the matches involving his favourite teams. Some of the players can pick him out of the audience, though they know him only as "that guy who goes 'auUuG!' all the time".
