Editing Second Foundation (section)

=== "Part I: Search by the Mule" ===
Part I is about [[Mule (Foundation)|the Mule]]'s search for the elusive Second Foundation, with the intent of destroying it. The executive council of the Second Foundation is aware of The Mule's intent and, in the words of the [[First Speaker]], allows him to find it—"in a sense". The Mule sends two of his people on a search for the Second Foundation: Han Pritcher, who had once been a captain and a member of the underground opposition prior to being Converted to the Mule's service, and [[Bail Channis]], an "Unconverted" man (one who hasn't been emotionally manipulated by the Mule to join him) who has quickly risen through the ranks and impressed the Mule.

Channis reveals his suspicions about the Second Foundation being located on the planet Tazenda, and takes the ship there. They first land on Rossem, a barren planet controlled by Tazenda, and meet with its governor, who appears ordinary. Once they return to the ship, Pritcher confronts Channis and believes him to have been too successful with the search. The Mule, who had placed a hyper-relay on their ship in order to trace them through hyper-space, appears, and reveals that Channis is a Second Foundationer. Pritcher's emotional bonds to the Mule are broken in the ensuing exchange between Channis and the Mule, and he is made to fall into deep sleep. With only the two of them left, the Mule reveals that he has brought his ships to Tazenda and has already destroyed the planet, and yet senses that Channis's dismay is only pretense. He forces Channis to reveal that Rossem is actually the Second Foundation, and that Tazenda is only a figurehead.

The First Speaker for the Second Foundation appears and reveals to the Mule that his rule is over; neither Tazenda nor Rossem is the Second Foundation, and Channis's knowledge had been falsely implanted to mislead the Mule. Second Foundation agents are headed to Kalgan and the Foundation worlds to undo the Conversions of the Mule, and his fleet is too far away to prevent it. When the Mule experiences a moment of despair, the First Speaker is able to seize control of and change his mind; he will return to Kalgan and live out the rest of his short life as a peaceful despot.
