Forerunner-Precursor war

"I am the last of those your kind rose up against and ruthlessly destroyed."

- The Primordial to the Didact.

Ten million years before the Forerunner-Flood war, the Forerunners rose up and destroyed their creators, the race of beings known as the Precursors, in a massive war. Though all Precursors were believed to have been eradicated, the Primordial, who originally claimed to be the last Precursor, later stated that a number of Precursors survived by escaping beyond the Forerunners' reach. The Forerunners' defiance of their creators may have been an act of self-defense, as the Precursors had allegedly decided to erase their species from existence, as they had done with many of their other creations.

This conflict took place so long before the time of the Didact and Bornstellar Makes Eternal Lasting that their respective generations had no knowledge of it.
