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.

Two headed dragons are a special breed of dragons. They have two necks, two brains, two mouths, but one stomach and one main body. The two heads usually work together, but there are times when they will fight each other, attacking back and forth. They use their sharp teeth and wings to hunt large animals, and rarely eat plants. It is unknown what would happen if a two headed dragon were to mate with a one headed dragon, since it has never occurred. They only mate within their breed.

Moonclaw and Sunfang, although a Split dragon, despise each other greatly. They are almost completely different and can be heard arguing with each other throughout the day because of their diverse personalities. Moonclaw is more of the silent type and prefers secluded areas instead of crowded ones. He is also most active at night, and likes to be around with the Sunset dragons. Sunfang, however, is the complete opposite. He loves basking in the early morning sun with the Sunrise dragons and is the loud, joyous type. Sunfang prefers to be in audience with many dragons at once. Because of their differences, the Split dragon can never agree on anything and annoy each other to death. The only thing that they had agreed upon was that Moonclaw would sleep in the day and Sunfang would sleep at night. Whenever this Split dragon is seen in the cave, one head is always dangling down, captured within a blissful slumber.
