The TechnoCore was a conglomerate of Artificial Intelligences that achieved self-sentience and acted as an organization, society and race; acting as a major player in the intergalactic affairs of the human race throughout the Hyperion Cantos saga.
AIl of the TechnoCore evolved from human hardware and software from the days before the Hegira, but they became an independent force in the galaxy and "seceded" from humankind. They maintained a relationship with their creators, however, and the Core had an adviser to the Hegemony, Councillor Albedo, who advised the Senate CEO.
The TechnoCore provided the Hegemony with the technology to maintain farcasters and fatline transponders, as well as all-time access to the Datasphere.
