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.

Dragons are highly-intelligent reptilian creatures that—from a human perspective, at least—appear to live forever. Many different varieties of dragon exist, each with their own unique qualities, habitats, and behavior. Adolescence in dragons 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. In Galsreim, dragons and humans coexist peacefully.

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.
