It has already been foretold. In the time after the Great Collapse there shall arise a man of singular purpose and mind, a great unifying force, who will lead an army the size of which has never before been seen on this Earth. This man will conquer all who stand before him. The oceans will turn red with the blood of those who try to resist. Sages will marvel at his conquests, and troubadors will sing of his exploits for a thousand years. That man shall be me.
