Foundation Season 3 Story

Set a century and a half after Foundation Season 2, there’s a powerful new enemy to contend with: The Mule. He seeks nothing less than full and total control of the universe – by any means necessary.

With all life under threat, both The Foundation and the Cleonic Dynasty are thrown into a deadly game of, as Apple TV+ puts it, “intergalactic chess.”

Foundation Season 3 Synopsis

Apple TV+’s official Foundation Season 3 synopsis reads: “The Foundation has become increasingly established far beyond its humble beginnings while the Cleonic Dynasty’s Empire has dwindled.”

“As both of these galactic powers forge an uneasy alliance, a threat to the entire galaxy appears in the fearsome form of a warlord known as ‘The Mule’ whose sights are set on ruling the universe by use of physical and military force, as well as mind control.”

“It’s anyone’s guess who will win, who will lose, who will live, and who will die as Hari Seldon, Gaal Dornick, the Cleons, and Demerzel play a potentially deadly game of intergalactic chess.”
