Location from Hyperion by Dan Simmons
The capital of the Hegemony — the political center of human civilization where Gladstone ruled and Albedo whispered, until the farcasters fell and the Web went dark.
Tau Ceti Center was the political capital of the Hegemony of Man — where the Senate met, where CEO Gladstone governed, and where Councilor Albedo delivered the TechnoCore's advice. It was the hub of the WorldWeb, the beating heart of interstellar governance. After the Fall, Tau Ceti Center — like every Web world — was severed from the rest of civilization overnight. The political center of humanity became an island.
An urban world — the New York/London/Tokyo of the Hegemony era. Government buildings, Senate chambers, and the kind of gleaming institutional architecture that says 'we are the center of everything.' FORCE headquarters are here.
Also known as: Tau Ceti Center, TC2
