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.

Aranniel was taken in just after Feinrian took the position of Queen and Leader of the Digi Clan. As a hatchling, she envied the attention showered upon Guilin, daughter of the queen, and secretly wished that the powerful black hatchling would perish before coming into her inheritance. However, Fate, it seemed, had a much crueler hand to play, and instead took away Guilin's twin, causing Aranniel to feel immense guilt over her jealousy once she saw the pain it caused every one. With a new resolve, she seeks to become queen, a Royal Star just as her name denotes, but first, she must dethrone Feinrian.

Upon her maturation, Aranniel immediately sought out a mate, and found a temporary one in Feanir, but his distaste for power left her seeking another as soon as she was able. Now, she is mated to Kanameishi, but who knows just how long that will last.
