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.

Shadow Leo tends to be a loner and doesn't socialize with the other dragons. He is often seen walking around the lake and basking on one of the rocks that surrounds it occasionally talking to one of the aquatic dragons, mostly AquaLeo the two finned bluna. Despite his tendencies to be alone, he is always one of the first to get on the battle field and strike out against any threat to his clan and has proven him self to be a worthy and capable warrior. Through his fighting ability he has gained the respect of several of the clan members.
