Forerunner-Precursor war

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

- The Timeless One to the Didact

Long 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. The Forerunners' defiance of their creators was an act of self-defense, as the Precursors had decided to erase their species from existence, as they had done with many of their other creations. 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.

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.
