10,000,000 BCE

Circa 10,000,000 BCE, the Precursors choose early humans to become the next species to carry out the 'Mantle.' Wanting to seize the mantle for themselves, the Forerunners rebel against the Precursors and push them out, eliminating almost all of the Precursors known to them. Only one known Precursor survived, in which who was the 'Timeless One,' and was held in deep stasis outside the Milky Way Galaxy and others turned themselves into an inert powdery substance. This dust would deteriorate throughout time and become what is now known as the parasitic Flood.
