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.

Bloodsplash is Geoslate's little goon. He is considered a rare dragon, since Dorsal dragons are normally purple. He is much younger than Geoslate, but the dragons of the Oibioib cave believe that he has a thing for Geoslate. Yet, no one understands how a weak little crony such as him could see through Geoslate's tough scales and see anything worth loving in that cold, stony heart of hers.
