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.

Flake enjoys swimming with Woosh; the issue being is they don't live in the same depth of water. Despite hating the light, Flake makes an effort to swim up to hang out with her friend. In return Woosh makes an effort to swim down a bit, they meet in the middle.

Flake is very considerate of other people's situations, though his only knowledge of the surface is stories from Woosh. With this considered he hopes to meet a surface dwelling creature soon, but it'll take him a while to muster the courage to deal with the extra light. Not to mention going near the land.
