What Season 3 of Foundation

The season begins 152 years after the events of the second. The Foundation has grown considerably since its humble beginnings, while the Cleonic Dynasty has lost strength. Both powers are forced to forge a fragile alliance. But a threat emerges for the entire galaxy: a warlord known as The Mule, who wants to dominate the universe through military force and mind control. Hari Seldon, Gaal Dornick, the Cleons and Demerzel move their pieces on an intergalactic board where any move can backfire. No one knows who will come out on top.
