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.

Ridcully is quite content studying magic without actually using it. He spends a lot of his time outside and enjoys physical endeavours more than one would expect from a magi. A lot of dragons make the mistake to assume this means he isn't very bright or has no talent in magic, but fact is Ridcully has a very sharp mind. It's just that he is also very practical which means he doesn't show off or uses magic when normal means would suffice.

He is very aware of his mate Glinda's character faults and has a lot more respect for Esme but since she refused him they are only friends and he avoids getting drawn into the two dragonesses' fights.
