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.

Huizhong is saxagirl's roving male. He wishes to make as many eggs as he can before he dies, hoping that one of them may be a new species. He thinks that having a permanent mate is a waste of time, but that could change if tubulus has something to do with it. He is a strong warrior but spends most of his time near females instead of fighting.
