High above the planet Tranquility, the Oversoul watches. Its job, programmed a lot of millennia ago, is to protect the human arrangement on this world, to safeguard this fragile remnant of Earth from all dangers. To protect them, primarily, from themselves.

The Oversoul did its job well. There is absolutely no war on Harmony. You will find no weapons of mass destruction. There is no technology that could lead to weapons of battle. By control of the info banks, and refined interference in the very thoughts from the people, the artificial cleverness has fulfilled its mission.

But now there is a problem. In orbit, the Oversoul realizes it provides lost usage of some of its memory banks, and some of its power systems are faltering. And on earth, men are starting to consider power, wealth, and conquest.
