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.

Thaebe is the mouthpiece of Red Rory and works as a messenger for those like him, who prefer never to come to the surface. It is his wish to have everyone live in peace, especially with the dragons of the surface. However, Thaebe has only warmed up to a single human, the clan caretaker, as if he has realised that another human had left him to die. Still, despite their friendship, they rarely meet. After all, he is bound to the darkest water and blackest sky, while she is often found all over the land, where he can rarely ever meet her. It is quite a pity in his scaly heart.
