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.

Pryn and Ora have a unique ability to connect to the future. Whenever the two combine their mental wave patterns, they feel transported through time and see things that are to happen. At first, the two were peppy, happy dragons. They were little rays of sunshine in the cave. Though one day, they decided to go far into the future to see what would become of the cave, the dragons, and humanity. When they came back, they were reclusive, silent, and shy. They hardly spoke to others but themselves, and remained in one corner of the cave. The others became concerned with this, and asked Ora and Pryn what was their fate. Though once asked, the two quaked fiercely and would retreat further into their cavern within the cave.
