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.

Norbert is a happy go lucky sort of dragon, he sort of floats along in his own little world. The affairs of others do not interest him, he enjoys being on his own but he is very happy in the company of optimistic persons. He does however have a strong hatred of pessimists, and will not tolerate them. He is considered by many of the other dragons of the cave to be quite dim, but in fact he isn't, he just hides his intelligence as he feels it will get him more love and comfort.

He loves watching the young of the cave go about their business, and he often likes to think of himself as a father figure, or grandfather figure, to them.
