When a galactic empire begins to fall, one mathematician builds a thousand-year plan to keep civilization alive.
Asimov's Foundation Universe is an independent fan magazine. Jason Guo edits it. AI tools help research and draft; facts are checked before publication. Long essays cover the books, the Apple TV+ adaptation, and where the two diverge. Behind them sits a reference library of all 15 books, the major characters, and a 20,000-year timeline. New to the saga? Start with the reading-order guide. This is a fan-maintained publication, not an official Asimov or Apple one.
Or play the Seldon Crises as Hardin and Mallow.

Books
Asimov wrote seven Foundation novels. Eight Robot and Empire books are often added to make the 15-book saga. Three later novels by other authors sit outside that count.

TRANTOR
A planet-sized capital glowing at dusk, beautiful enough to believe in and fragile enough to fall.
PSYCHOHISTORY
Hari Seldon's equation becomes the cinematic engine: a future mapped through pressure, probability, and fear.

A small outpost carries the weight of civilization after the lights of the Empire begin to go out.
