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.

Charm and Elegance. Two of the many skills that Nessie has. I guess that's what led to her having an egg with an already mated for life dragon. Snapdragon would be devastated if she knew what her mate had done—an egg with this tramp! How dare he. But Nessie is the only one who lives with this secret now. Sky seems to forget the incident, and Snap never knew. Now she's alone with a fatherless egg.
