Men of Gold
Men of Gold are a mysterious sect of Humanity that appeated during the Age of Terra. They were physically and emotionally superior than ordinary men, and used them to learn and spread across the Old Earth, turning the anarchy of Nature into the order of Civilisation. To help them colonize Galaxy, Men of Gold created Men of Stone, which surpassed their masters in population in M21. With the start of Dark Age of Technology, most of them disappeared. Characteristic-wise, they could be considered similar to the Perpetuals.
