第二基地
The Darells are left on Trantor. The Mule leaves to reign over the Foundation and the rest of his new empire. Existence of the Second Foundation, as an organization centered on the science of psychology and mentalics, in contrast to the Foundation's focus on physical sciences, is now known to the Darells and the Mule. Now that the Mule has conquered the Foundation he stands as the most powerful force in the galaxy, and the Second Foundation is the only threat to his eventual rule over the entire galaxy. The Mule promises that he will find the Second Foundation, while Bayta asserts that it has already prepared for him and thus that he will not have enough time before the Second Foundation reacts.
