This war is the Change War, a war of time travelers—in fact, our private name for being in this war is being on the Big Time. Our Soldiers fight by going back to change the past, or even ahead to change the future, in ways to help our side win the final victory a billion or more years from now. A long killing business, believe me.
You don't know about the Change War, but it's influencing your lives all the time and maybe you've had hints of it without realizing.
Fritz Leiber, "The Big Time"
