The fall of the Galactic Empire heralds a new era of barbarism, but a hidden society of scientists plans to shorten the dark ages through the science of psychohistory. Hari Seldon, the brilliant mathematician who developed psychohistory, predicts the imminent collapse of the vast Galactic Empire and a subsequent 30,000-year period of chaos. To mitigate this, he establishes two Foundations at opposite ends of the galaxy: one to preserve knowledge and another, secret one, to guide humanity's future. The narrative follows the struggles of these Foundations as they face external threats and internal manipulations, all while navigating the predetermined path laid out by Seldon's predictions.
