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.

Gold dragons are the ones most often killed by humans, who consider their scales to be extremely valuable. These golden scales grant them a high level of protection, similar to armor, and they use this to their advantage in battle.

Senor Goldensish is a rare, elusive golden dragon, which meant his egg was hard to acquire. After much hunting and missing, the Master was extremely  happy to find his egg. After he hatched, it was learned he was descended from noble Spanish dragons. The master spent much time polishing the little hatchling so he shown brightly. He was somewhat timid at first being the brightest dragon in the Sanctuary and others were just as nervous to approach him. He stayed pretty isolated and distantly awed till a spunky little skywing bumped into him. Senor laughed a chiming laugh at the tangled skywing. After he helped her, he asked if she would stay and talk with him. Other dragons noticed that the Senor just a nice dragon and now he's a pretty well liked dragon and has successfully brought more of his kind to the dragon Sanctuary, brightening the place up with all the shininess.
