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.

Leader of the Mint Horde. Uno took place after the first left his position to go into the wild. She leads the Mint Horde with pride, as she knows that she is the future of their rebellion. They want a more "peaceful cave" and to have the dragons to "stop killing the animals." So, they throw any dead animal they can find in the cave off a nearby cliff. Uno is known to steal Blossom's eggs and hide them; much to the annoyance of Blossom. She has full command over the Horde, but she actually is very peaceful.
