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.

Sunset dragons are closely related to sunrise dragons. However, their behaviors differ greatly. Sunset dragons generally live alone or in small packs. They are more active in the evening, hunting and performing all of their daily tasks as the sun sets.

Sunset is the highlight of Crepuscula Magnifica's day. She loves the purples and oranges in the sky, and has been known to breath fire into any clouds that are spoiling it for her, to dissipate them. After the sun goes down, she likes to dance the macarena with anyone who will join her - she can keep it up all night. Come morning, she loses interest, and makes herself a strong cup of hot mead before retiring to a corner to sulk at the injustice of daybreak.

Any children she has had better not need attention during the day, as they aren't likely to get it.
