Dorsal Dragons are so named because they have large fins along their backs that can be raised and lowered at will. They use these fins to regulate body temperature; they raise them to cool off when they become overheated. The bright colors on the fins double as a means of attracting mates.

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.

Devious as she might be, Brize is a warm and friendly dragon. She'll often watch over the young hatchlings, letting down her fins just enough so they can crawl over them, the bright colors alluring to their naive minds. Her main duty is to watch over the young ones, a job she doesn't mind at all. She is often forced to chase after one that has wandered too far from the castle grounds, quickly overcoming the smaller dragon in a few bounds. Her kindness might have originated from a harsh incident in her past. As a small hatchling, she liked to fool around, playing jokes on the older dragons. One fateful day, however, she went too far, almost costing a dragon their flight. The scolding she received was one that could have frightened the most hardened dragon, and it stuck with her. From then on, she swore never to be as harsh to those who couldn't understand what they'd done wrong.
