that as it has accurately predicted previous events, the Foundation's formation of a Second Empire is inevitable. The leadership of the Foundation has become dictatorial and complacent, and many outer planets belonging to the Traders plan to revolt. An external threat arises in the form of a mysterious man known only as the Mule. The Mule (whose real name is never revealed) is a mutant, and possesses the ability to sense and manipulate the emotions of others, usually creating fear and/or total devotion within his victims. He uses this ability to take over the independent systems bordering the Foundation, and has them wage a war against it. In face of this new threat, the provincial Traders join with the central Foundation leaders against the Mule, believing him to be the new Seldon crisis.

At the Great Library, Ebling Mis works continuously until his health fatally deteriorates. As Mis lies dying, he tells Toran, Bayta, and Magnifico that he knows where the Second Foundation is. Before he can reveal the Second Foundation's location, however, Bayta kills him. Bayta had realized, shortly before, that Magnifico was actually the Mule, who had used his powers in every planet they had previously visited. In the same way, he had forced Mis to continue working and find what the Mule was looking for. Bayta had killed Mis to prevent him from revealing the Second Foundation's whereabouts to the Mule. The Darells are left on Trantor. The Mule leaves to reign over the
