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.

Two-Finned Blunas are a very social breed of dragon, living in packs of dragons called "pods." Blunas are very curious and playful creatures and several dragons in a pod will often "play" with one other, chasing each other around, tossing seaweed back and forth, and riding ocean swells. They are occasionally seen swimming alongside whales and dolphins.

Bluesweeper is a male Two-Finned Bluna of the Featherwing Weyr. He was raised alongside Bluedeeps, another male Two-Finned Bluna, so the two of them are like brothers. Bluesweeper is the quiet, poetic one who gets nervous around pretty females and can't stand to be embarrassed in any way. He's a very deep, intellectual dragon, but for a long time, he felt no one noticed it in the shadow of his like-brother's charisma. However, since then he met and fell in love with his dear mate, Blueshell, who gives him strength and confidence with her constant support and love.

Bluesweeper and Blueshell would love to have hatchlings someday.
