Mint colored dragons are the most peaceful of all dragons; they only eat plants unless they scavenge meat from an already dead animal. They also have no ways to attack others or defend themselves. They are much smaller than other forms of dragons since they only double in size when they mature. Mint dragons are unable to use magic and cannot fly since they lack wings. Their looks have given rise to the common insult of calling dragons “large lizards.”

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.

Jealousy's besetting sin is thievery. He has been known to steal things from his owner when she isn't paying attention. Everything from small items up to their train of thought have been stolen by Jealousy. One day when Eva was setting up a task for her game "Evangeline Says", living up to his name, the small mint dragon got jealous and distracted his owner. She chuckled and went to give her attention to the small dragon. When she finally came back, still holding Jealousy, she forgot totally that she was on task six. Instead she put task seven and Jealousy never bothered to tell her. He simply stole away task six and continued to receive her attention.
