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.

Mega Sableye lives in a cave and isn't often seen by humans. That's just as well, since she has a sharp-toothed "grin" that chills them, and they say that looking into her red eyes will deprive them of their soul. She doesn't have a hoard in her cave like some dragons, but she does carry an enormous jewel everywhere she goes.
