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.

Skywing dragons spend most of their lives flying in the air. They hunt from the air, diving at prey from above, and land only to rest. They are some of the fastest fliers, capable of extremely high speeds. The webbing at the end of the tail acts as a rudder, allowing them to easily change direction during flight.

Mimei helps her mate, Kaitou Yue, run a small clinic at the southern border of the Kyokos Vale. Although she doesn't possess any healing magic, she contributes significantly to the clinic's success. Every few days she flies into the human lands to spread the word of her mate's free treatment. In emergency cases, or when the patients are too sickly to make the journey on their own, she offers to carry them. For that purpose she carries a huge woven basket tied across her back. It's large enough for two adults to lie side by side, and lined with thick blankets to prevent wind chill. She loves Yue, but his philosophy that healing should be free for everyone sometimes rankles, since her greatest love (after her mate and children) is the glitter of large gemstones. As a compromise, in return for a ride, she asks for stories of treasure. It's always fun to hear about the nobles' newest acquisitions. (And possibly imagine how they would look nestled within a certain hoard.)
