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.

Delirium comes from a proud line of royal magic users. While as a hatchling she took delight in almost everything around her, her use of chaos-magic has changed her. Nowadays her personality seems unstable, shifting constantly between childlike wonder, manic-depressive phases and even short perios of real wickedness.

The time when you should be really afraid of her though is when her two mismatched eyes suddenly show the same colour, because then she is in CONTROL - a state she doesn't like but assumes when she deems it necessary to protect her clan.
