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.

Bright pink dragons are one of the few all-female breeds of dragons. Their bright colors make them easy to spot during dragon mating season. They are primarily herbivores, but eat meat during mating season when it is brought to them by a mate. Mating seasons occur once every 200 years and can last up to 2 years.

Rozalita, 12th of the Tolander clan, is the only dragon in the Tolander cave to have a pet: a male human. Because Roza is a relatively small dragon, her human is about half as tall as she is, but light enough to ride her back when she flies (when she lets him). He does not seem to mind being around dragons, perhaps because Roza dotes on him and ferociously snaps at anyone who comes near him. She is usually, however, sweet-tempered. She, like some of the other younger female dragons, has a crush on Rizemaison, who barely knows she exists.
