One hundred thousand years ago, when the Forerunner empire faced destruction, Chakas and Raiser, like sailors washed off the deck in a storm and thrown onto an unknown shore, woke up in a very strange place, on a damaged and abandoned ring world where human life looks like a bad dream, full of absurdity and horror. Chakas, who has lost his friend, sets off on an incredible journey, hoping to find his way home. He does not know that he has already become a pawn in an ancient game of revenge, in the struggle of powerful forces: the Primordial - a mysterious being, the progenitor of life in the Galaxy, and the Forerunners, who inherited the Mantle of Responsibility - the right and duty to protect and nurture less developed races.
