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.

He was pacing in the clearing, he was angry, at his mother and the clan, but mostly his mother. She said that he had to be the next medicine dragon because he was the oldest. He didn't want to be the medicine dragon, he wanted to be the AutumnClan's inventor dragon. That was when he came across an egg. It was a White dragon egg, this was his chance! The egg became Star of White Wings and the other medicine dragon. And Nights Last Wish became the inventor of AutumnClan. He invented many things but he thought the best ones were a time machine, and a way to make flightless dragons fly. Some of the hatchlings dislike him for inventing math, but not many.
