(PROSE: The Day of the Doctor C8)

However, the day came when the Time Lords of Gallifrey decided that the Dalek mutants posed a threat of all reality, and so attempted to use their time-travel abilities to cancel them from existence. The attempt failed, and the Daleks used their own time-0ravel machines in a similar attempt to cancel out the Time Lords. And so time became a weapon in a war that could never end, and the conflict spread not only through space, but backwards and forwards through history. Days became battle lines, and century turned on century, and divergent time streams found themselves fighting each other for the right to exist. It was said, one soldier could die a thousand times in one day of that war, and discover he'd never been born the next. And so, when the Doctor heard that cry for help, there would have been countless billions across the universe suffering in exactly the same way.
