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.

Silver dragons are arguably one of the most beautiful types of dragons. They live in high altitude habitats such as mountains. Male silver dragons hunt and eat meat. While not as beautiful or radiant as females, silver males possess better physical attributes, such as strength.

Spiro is a very calm, very beautiful dragon. His aura shines brightly like the moon and the stars. He is a silver dragon, which is a very rare breed of dragon. His rarity rivals that of the famed Gold Dragon. Like Golds, his breed was also pushed to the edge of extinction due to high demand for the silver's beauty. Spiro is very gentle, and dislikes violence. Because of his gentle nature, he will do anything he can to avoid conflict.
