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.

Dark green dragons, once they mature, appear to become an entirely different species. However, this isn't true. Rather, they burrow underground and get nutrients from their vines. These vines are sometimes referred to as Dragon Grass. These dragons are very violent, and will use their vines to capture, kill, and eat anything that moves, as well as nearby plants. Luckily, their range is limited and they cannot use magic. Dark green dragons tend to be easy to spot since they usually kill all plants around them and thus are usually surrounded by a large clearing.

Since Raezel's father is already in charge of protecting the Dragonreaper's lands with vicious plants and trap vines, Raezel focuses more on the aspect of beauty. Raezel serves as a groundskeeper, a job he loves and loathes. The plants he aids in growth are all various forms of lovely but deadly Dragon Grass. Any other plants are devoured by either himself or Zizmo.

Raezel also struggles with the concept of beauty, and the concept of destruction. The two fight in his mind. While he's less social than his father (and of course, Zizmo is not at all social) he is also less aggressive due to this conflict and could become cordial with many of the other dragons if only he could overcome his internal struggles.
