The opening episode begins on Trantor, capital of the Galactic Empire, with the meeting of Seldon and Dornick, their trial, and their exile to Terminus. The action then jumps forward 50 years, to the first Seldon Crisis, where the repercussions of the recent independence of the Four Kingdoms of the Periphery are being felt on Terminus, and are handled by the first Mayor, Salvor Hardin. The scene then moves forward a further 20 years, as Mayor Hardin faces down the domination of the nearby and most powerful Kingdom, Anacreon.

Changes from the written Trilogy: The conflict between The Foundation and Anacreon takes place 70 years into the Foundation era; in the novels it occurs at 80 F.E. A small segment in Foundation titled "Traders" has been removed entirely. General editing for time has been done throughout. A large, rather comedic section on farming on Rossem has been added to "The Mule Finds".
