00:00:00.000 --> 00:00:05.000
A maintenance worker walks alone through a narrow utility tunnel carrying one warm inspection lamp. Every ceiling light switches off behind her in sequence, approaching like a wave of darkness.

00:00:05.000 --> 00:00:09.000
She reaches a sealed observation door and wipes condensation from its small window. A low mechanical heartbeat begins beneath the floor.

00:00:09.000 --> 00:00:13.000
The door opens. The camera moves past her into a cavern containing an enormous dormant city descending for miles underground. One tower after another powers on, revealing bridges, transit lines, and millions of empty windows.

00:00:13.000 --> 00:00:15.000
A single window at the deepest level lights up and a distant silhouette looks directly toward the camera. Hard cut to black.
