Dragons are creatures with nearly unlimited life spans. They can survive for long periods of time, and no one has found a dragon that has died of old age. Adolescence 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. Once they hit adolescence, hatchlings change quickly, maturing to their full forms in only 2 years.

Dragons don't communicate with each other verbally, but they will growl to scare off predators and frighten prey. Young dragons will emit an extremely high-pitched squeal when they are frightened. To communicate, they use telepathy with each other and to speak to other creatures.

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."

Foxe is the little messenger for the clan. He is one of the most insignificant, and not the fighting type. Despite his low rank in the clan, Foxe still proves his worth as much as possible. He hates being cuddled, since he is one of the cutest dragons. He has an assistant with delivering letters named Miff, a frozen baby mint. Sarunikae and ZakeraZero keep their clans close, and helps each other out by sending messages back and forth with the messengers of the clan.

Nimaru and Nichan are both in different clans, Nimaru being in Sarunikae's clan and Nichan in ZakeraZero's. They are both deeply in love, but aren't able to see each other much at all, so they use Foxe and Miff to send messages back and forth.
