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.

When water dragons mature, they lose their legs and the ability to survive on land, entering the water permanently. They are adept swimmers and eat whatever fish are in the lake they live in. They tend to inhabit the same lake for their entire lives, although a few live in the ocean and swim all over the world.

When Narad first became a dragon keeper, her obtained four eggs: a black, two whites, and a green. The black egg was the first one she got, and the first one that died.

The remaining three eggs were abandoned, because Narad hoped they would still have a chance of finding another dragon keeper that could take care of them and help them survive. A few days later, Narad chanced upon a water dragon hatchling, and took him under her wing without hesitation.

Xaraqanselo was Narad's first dragon to live to see adulthood. He is a very cautious and gentle dragon, and dislikes the darkness of the deep trenches in the lake he inhabits, Loch Gardavan. Xaraqanselo loves music, especially bagpipes and drums, as when he was a hatchling, Narad played music for him every morning. His living relatives are his father, Spermatozoon, and his mother, a white dragon named Aeris, and his older sibling, Arquaxion.
