The opening episode begins on Trantor, capital of the Galactic Empire, with the meeting of Hari Seldon and Gaal Dornick, their trial, and their exile to Terminus. The action then jumps forward fifty 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 moves forward a further twenty years, as Mayor Hardin faces down the domination of the nearby and most powerful of the Four Kingdoms, Anacreon, whose ruler intends to annex the Foundation by force.
A hundred and fifty years after the Foundation was established, the now powerful trading nation, guided by master trader Hober Mallow, faces its greatest threat to date.
Two hundred years after its creation, the Foundation battles Bel Riose, the last powerful General of the dying Galactic Empire.
A further hundred years have passed, and the Foundation is challenged by an unexpected threat named The Mule.
During the war against The Mule, with things going badly for the Foundation, some key figures under the leadership of the Foundation's greatest scientist, Ebling Mis, flee Terminus in search of the Second Foundation, to warn it of the danger from The Mule.
The Mule attempts to find and overthrow the Second Foundation.
Sixty years later a teenage girl is at the centre of the Foundation's renewed search for the Second Foundation.
The conflict between The Foundation and Anacreon takes place 70 years into the Foundation era; in the novels it occurs in year 80 F.E.
A small segment entitled "Traders" in the first volume, Foundation, has been removed entirely
General editing of the timescale has been done throughout
