They were our allies before the forerunners devolved us and died while we came back to earth not as technologically advanced as we were (in halo terms). But my question is why don't the remember us after being restricted from us? Is it because we didn't surrender to the Forerunners as they did and they had to follow their word? Maybe there orders we to be against Humans, but Humans don't remember and the prophets never brang it up. I guess that was part of the treaty. The meeting up of them two was forbidden but they end up facing eachother in war.
