Civia, our hero is the last hope for our Earth, our dimension. The Congregation is Convinced: few are saved realities of war and the extinction of the human race and the destruction of the planet.
Congregation gets in contact with other realities to give help to Civia to save the world without him knowing it at all. "We can not contaminate the sample" - assure the members of the congregation - "It would be dangerous for everyone, but someone has knowledge and experience to help you." So they decided to summon Rescuers failed in other universes, giving Civia good advisers by his side.
The hope of mankind is changing humanity itself, prevent wars through language, focusing on the language Anthology of Nietzsche. So travel to various "stops" at fixed points in time, contingencies, unlike most situations in the flow of time, can not change. Thus way changing the course of history, making the impossible, even traveling at the last stop: the result of his actions, eliminate that failed to save them all, humans not got it.
