I have this idea which I called the Chronicle. The Chronicle are a line of beings who chronicle the passing of time during the course of it. They die when they finish their book. But they have the ability to alter the past by rewriting bits of their Chronicle. the story was that a group of fellows venture out, upon hearing the myth of the Chronicler, so they can alter the past and make themselves the rulers of the world, but along their way, they change, and become better people. While they are on their journey, their homeland is attacked by beings from the Chaos Beyond. And so they go to the Chronicler, pleading to rewrite history, so the Chaos never attack. etc etc
