Editing Second Foundation (section)

=== "Part II: Search by the Foundation" ===
Part II takes place 60 years after the first part, 55 years after the Mule's death by natural causes. With the Mule gone his former empire falls apart and the Foundation resumes its independence. Because of their enslavement at the hands of the Mule and their wariness of the Second Foundation (who possess similar abilities to the Mule) the Foundation began studying the mental sciences.

A secret cabal is formed within the Foundation to root out the Second Foundation after evidence of the latter's manipulation is found through mental analysis of the former society's key figures. They send one of their own, Homir Munn, to Kalgan to search for clues to the Second Foundation's location. Munn is followed to Kalgan by Arcadia, Dr Darell's daughter.

Since the death of the Mule, the Second Foundation has worked to restore the Seldon Plan into its proper course. In the organization's secret location, the First Speaker discusses the state of the galaxy with a student. The Student is concerned that the Foundation's now tangible knowledge of the Second Foundation's existence would have negative effects upon the former which would then further destabilize the Seldon Plan. The First Speaker reassures the Student that a plan has been put in place by their organization in order to address his very concerns.

In Kalgan, a man named Stettin has assumed the Mule's former title as First Citizen. He believes that the Mule's actions have made the Seldon Plan irrelevant and declares war upon the Foundation, intending to usurp their role in the formation of the Second Empire. He's unconcerned with the possible intervention of the Second Foundation.

Arcadia escapes from Kalgan to Trantor with the help of a Trantorian trader named Preem Palver. With his help, she passes information to her father regarding the location of the Second Foundation.

Kalgan eventually loses the war against the Foundation as the specter of the Seldon Plan adversely affects the performance of the Kalganians every bit as much as it bolsters the morale of the Foundationers.

The Foundation cabal reconvenes to discuss what they've learned about the Second Foundation. Munn believes that the Second Foundation never existed while Pelleas Anthor believes they're in Kalgan. Dr Darell states that the Second Foundation is in Terminus itself based on information supplied by Arcadia. He also reveals he has created a device capable of emitting mind static, which is harmful to individuals with mental abilities similar to that of the Mule and the Second Foundation. Activating the device in the presence of the cabal reveals Anthor to be a Second Foundationer, and further interrogation leads to the discovery of the rest of his comrades who are subsequently detained indefinitely.

Unsatisfied with the ease by which the Second Foundation has been defeated and suspecting Arcadia's information to be planted through mental tampering, Dr Darell runs tests on his daughter to determine if she has been compromised. Both are relieved when the tests' results are negative. Dr Darell basks in the realization that with the Second Foundation gone, the First Foundation is the sole inheritor of the Seldon Plan and the Second Empire.

However, the Second Foundation is not only intact but has planned and orchestrated the recent major events. The Foundation's conflict with Kalgan and their subsequent victory was meant to restore the former's self-esteem after the Mule enslaved them. Anthor and his comrades were in fact martyrs meant to mislead the Foundation into believing they had eliminated the Second Foundation, thereby shrouding the Second Foundation in secrecy once more and restoring the Seldon Plan to its proper course. Arcadia was unknowingly working for the Second Foundation, having been mentally adjusted shortly after her birth in order to prevent detection. The Second Foundation is actually located at the planet Trantor, the seat of the former Galactic Empire.

The story closes with the revelation that the First Speaker of the Second Foundation is Preem Palver, who is satisfied that the galaxy is now forever secure.
