Foundation
Isaac Asimov's original Foundation trilogy follows a settlement of scholars who are exiled to preserve knowledge, discover that their encyclopedia is a decoy, and improvise religious, commercial, and political power under the authority of Hari Seldon's hidden historical plan. The Mule's unexpected conquest and the Second Foundation's mental manipulation turn the premise into a dispute: does long-range stewardship depend on secrecy, or does secrecy make the plan impossible for its supposed beneficiaries to govern?
Can experts protect a civilization's future without turning their model into an unaccountable source of authority?
