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.

Sinchi lives in the mountains, like all of the other gold Incan dragons. His name means "leader" in Incan. He was named because his egg had a dark splotch that resembled half of the symbol of Viracocha (Quetzalcoatl) on it, and when he was hatching, the cracks on his egg formed the rest of the symbol. Right then the elders decided that this hatchling was a special one. Watching over him, the elders named him "leader" because they thought he was a gift from the Incan gods and was destined to rule over them one day. So far Sinchi has shown no interest in leadership and goes out of his way to avoid being in a position of power. Maybe the supposed divine symbol was just a coincidence.
