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.

Kisao is a free spirit. There is nothing in the world he fears or hates more than a cage, be it physical or metaphorical. Most of his time, he spends in the air, soaring gracefully across the world, discovering its wonders and exploring its mysteries. Despite his youth, his wings are exceedingly strong and this allows him to remain airborne for weeks on end. He even sleeps in the sky, riding the thermals so as not to fall.
