Led by its founding father, the great psychohistorian Hari Seldon, and taking advantage of its superior science and technology, the Foundation survived the greed and barbarism of its neighboring warrior-planets. Against the odds, the group fought off destruction with cleverness and courage. Yet now they must face the full wrath of the Empire - still the mightiest force in the Galaxy even in its death throes.
When an ambitious general determined to restore the Empires glory turns the vast Imperial fleet toward the Foundation, the only hope for the small planet of scholars and scientists lies in the prophecies of Hari Seldon. But not even Hari Seldon could have predicted the birth of the extraordinary creature called the Mule - a mutant intelligence with a power greater than a dozen battle fleets, a power that can turn the strongest-willed human into an obedient slave. This mysterious entity possesses a force and stature beyond anything humany conceivable.
But even more terrifying than its strength are the eyes it keeps hidden beyind impenetrable shades - eyes that are rumored to have the power of death. Who - or what - is the Mule? And how is humanity to defend itself against this invulnerable avatar of annihilation?
When the Empire sent an Imperial fleet toward the Foundation, the only hope lay in the prophecies of Hari Seldon.
