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.

Mentha Drake holds no true role in Shield Tail and Dark Drakon's dragon herd. Instead, the dragons view her as a beloved pet, and this tiny dragon is often seen playing with the herd's hatchlings in a manner similar to how a dog plays with human children. While Mentha Drake loves all the dragons in the herd, she seems to hold a particular liking for Shield Tail, and will often accompany the dragon leader everywhere she goes.
