Deep beneath the earth, hidden by steel and humming servers, the first stable time machine activates. The underground lab vibrates as atomic clocks desynchronize. A circular distortion of light forms in the containment chamber—not a portal, but a fracture in time. Monitors flicker as historical records fluctuate; names vanish and dates rewrite. The machine has opened access to history. Across the infinite flow of civilization, empires rise and fall, unaware that a visitor from 2026 is about to enter their world. Kings wage war, philosophers write, armies march. The timeline waits for the first destination.
