The Forerunners were an ancient civilization whose power shaped the Milky Way long after their species disappeared. Their ecumene joined countless worlds through slipspace, artificial intelligence, megastructures, and technologies that later cultures could often operate without truly understanding. This episode introduces the Forerunner rates, the political struggle between Builders, Warrior-Servants, and Lifeworkers, and the belief that the Mantle of Responsibility gave them authority to protect and govern life. Their greatest achievements included shield worlds, artificial planets, the Domain, vast fleets, and the Halo installations. Their greatest failure was believing technological superiority guaranteed moral and strategic wisdom. Wars against ancient humanity, rebellion against the Precursors, and the return of the Flood pushed the ecumene toward civil conflict and extinction. The Forerunners are not merely mysterious builders who left useful ruins. They are the fallen superpower whose decisions created the central weapons, enemies, and inherited responsibilities of the modern galaxy.
