Yet all is not well with the Galactic Empire. Its vast size is crippling to it. In particular, the administrative planet, honeycombed and tunneled with offices and staff, is vulnerable to attack or breakdown. The only person willing to confront this imminent catastrophe is Hari Seldon, a psychohistorian and mathematician.

Seldon can scientifically predict the future, and it doesn't look pretty: a new Dark Age is scheduled to send humanity into barbarism in 500 years. He concocts a scheme to save the knowledge of the race in an Encyclopedia Galactica. But this project will take generations to complete, and who will take up the torch after him?
