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.

Magi dragons are, as their name suggests, primarily magic users. They rarely use physical forms of attack. They eat anything they can kill, which is almost everything. They won't kill unprovoked except when hunting, although they may kill humans if in danger. Their strong magic makes them one of the most feared breeds of dragons.

Fernando is a lively joker, but only to those that he knows well. Otherwise he is shy towards others, and they to him, due to his strong magic. He is constantly adapting his magic, learning to do different things in different ways. Nikko, the human who raised him, is his constant companion. They are rarely apart, and do even the most everyday, boring tasks together. However, Fernando often despairs that Nikko cannot perform even the simplest magic, despite being taught by the orange dragon. Fernando loves all of his dragon brothers and sisters, apart from DiamondSlate, whom his mage's mind finds hopelessly uninspiring.
