And there can be no question that the glorious powers that imbue him, and give his companions such strength in battle, are real beyond any doubt. Perhaps the Omniscience is a liar, deep in its prison of stone, and not the world's creator at all, but Omniknight never again questioned his faith. Thus the All Seeing One claimed to have created the world, and given the other truths revealed to Purist on that day, the knight had no reason to refute the story.

The Omniscience had formed the immense mineral shell of the planet around itself, as a defense against the numerous terrors of space. It had not merely dwelt in those rocks for billions of aeons no, It had created them. The Elder Hierophant led him on a journey of weeks down into the deepest chamber, the holy of holies, where waited not some abstract concept of wisdom and insight, not some carved relic requiring an injection of imagination to believe in, but the old one itself. For as he faced them down, he began to glow with a holy light, and they saw that the Omniscience had chosen to reveal Itself to him. No knight had ever questioned them before, and they tried to throw him into the pit of sacrifice, but Purist would not be moved. But over the long years of the crusade, as his elders passed away and were buried in sorry graves at the side of muddy tracks, as his bond-brothers fell in battle to uncouth creatures that refused to bow to the Omniscience, as his own squires were chewed away by ambush and plague and bad water, he began to question the meaning of his vows-the meaning of the whole crusade.ДЄfter deep meditation, he parted ways with his army and commenced a long trek back to the cave-riddled cliffs of Emauracus, and there he set a challenge to the priests of the Omniscience. Theirs was a holy struggle, and so embedded was he in his duty that he never questioned it so long as he had the strength to fight and the impetuous valor that comes with youth. He had spent his entire life in the service of the Omniscience, the All Seeing One.
