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.

Dorsal dragons are so named because they have large fins along their backs that can be raised and lowered at will. They use these fins to regulate body temperature; they raise them to cool off when they become overheated. The bright colors on the fins double as a means of attracting mates.

Though normal for a dorsal dragon, Kimian has found his black and violet coloring appears particularly ominous to those not familiar with his breed. The reclusive young dragon uses this to his advantage to scare away intruders, telling them he is a powerful dark wizard if his appearance alone doesn't do the trick. In his time he has claimed to have control over everything from gravity to time to death itself. In reality he has no magical ability and can not cast even a single spell. He enjoys his solitude, spending each day sleeping, eating, and contemplating the meaning of life.
