[quote]who are the Precursers.[/quote] The Precursors are a species that predate the known universe by approximately 96 Billion years. Throughout that time, they have gone through many iterations, taking different forms with different levels of technology. [quote]What did they do?[/quote]They are responsible for the creation of large swaths of life in the Milky Way galaxy. Most notably being Forerunners and humans. [quote]Where are they from?[/quote]There is no known point of origin. However, I theorize that they are the physical manifestation of living time based on how living time behaved in ways that mimicked the Precursors "disposition" in at least one instance pointed out by characters in Silentium. If they are the physical manifestation of living time, it would mean that they are a law of reality, and can not be defeated. [i]"Like water I ebb and flow. Defeat is simply an addition of time, to a sentence I never deserved, but you imposed." "Arrogant creature! Your death will be instantaneous, while we shall suffer the progress of infinitude!"[/i]

The precursors are aliens who created humans and forerunners,then decided to kill the forerunners but instead they got their ass kicked by the forerunners and only one precursor remained. (Is this close enough?)
