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.

Saturn the Chaste has little time for the daylight world.

Her contemplation covers the motions of the stars, and she tracks them closer than even the cave Nebula dragons, for they pick a single body to observe, and the Chaste watches them all. She has even developed her own system of notation, and keeps extensive notes in her lair.
