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.

Red dragons are similar to typical story book dragons. They shoot flames, can fly, etc. However, they aren't evil creatures as depicted in myths and won't go around raiding castles, killing knights, or kidnapping princesses. They live in a variety of habitats, from forests to coastlines to abandoned castles, usually in warm climates, and eat whatever living creatures they can find.

Ragnaroc is the tall, dark and silent soul-mate of the cave matron, Ragnarosa. You can usually find him near her either playing with the hatchlings or hiding in the shadows. Sometimes, he stays behind in the cave to watch over the eggs when Rosa goes to visit Hiromi with the hatchlings. Even when watching over the eggs, Roc can never find a moment of peace. Either he is being mobbed by the other dragons to play or he is fending off the constant and now playful attempts by Aurora to steal his heart. Her attempts annoyed him at first until the two storm lovebirds, Romana and Mamoru, decided to get Aurora together with her now soul-mate Cahir. Now she only flirts with Ragnaroc to make her mate jealous or to cheer poor Roc up when something gets him down.
