Battle of High Charity

	But what the San’Shyuum left unsaid was that the Prelates, on the order of the Prophet of Truth, were secretly retrofitting the Jiralhanae’s ships and training them to attack the Sangheili. Contrary to what he preached, Truth knew only a blessed few could follow him on the Great Journey. And after the Sangheili committed the ultimate sin of losing the first Halo ring, they quickly fell out of favor. So the Prelates redoubled their clandestine preparations and, as much as Rtas hated to admit it, had the Flood not intervened in the battle for High Charity, the Prelates likely would have succeeded in carrying out Truth’s wishes.
