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.

Scarlet Ray, better known as simply Scarlet, is inseparable from Violet Bolt. Both their eggs mysteriously turned up at the entrance of a clan's cave, many years ago. The clan took in the two eggs (who they assumed to be sisters, even though their parentage cannot be proven) and raised them as if they were not adoptees but blood members of the clan. The two have lived their lives as one since birth. They are very talented fighters, acting together as a tag team in a fight.

Scarlet is the more careful of the two, and comes in behind her overeager sister in a fight. She protects Violet's flank since Violet is too busy to watch it herself. Scarlet is calm, kind and diplomatically inclined. Because of her and her sister's dispositions, Scarlet often finds herself diffusing hostile situations generated by her sister—or cleaning up her sister's messes.
