Farcasters in "Hyperion Cantos" series

In Dan Simmons's "Hyperion Cantos" series, "Farcasters" are a central element of the universe's technological infrastructure. Farcasters create portals that allow individuals and goods to be transmitted from one farcaster terminal to another terminal across the universe. The concept of Farcasters shapes the universe's geography and society, as they influence trade, communication, and the movement of people throughout the interconnected worlds.
