The Final Emperor

There was a planet massive and vast. It was alone in the world, closest to the beginning, and furthest from the end. There was no end to what someone could do on such a plane. However, in such a place, Rei was alone, wasting away as he did nothing. Since the beginning of time there has been countless emperors that reign over the masses. The 5 Good Emperors, The 4 Evil Emperors, The Elemental Emperors and many more on top of that. So why..... why now will The Final Emperor emerge, who will it be? And why will he be? Who knows, I sure as hell don't.
