The echoes in the static.

Chapter 20: Silence Over Oakhaven

Inside the vault chamber, the master core server glowed with an intense purple light.

A massive digital countdown timer was mounted above the central display terminal: 00:14:22 and ticking down fast. When it hit zero, the archived surveillance data would leak across global networks.

Elias and Riley hurried to the main control deck.

"The system is running on an isolated quantum key," Riley said, her fingers racing across the physical keyboard interface. "A standard purge won't work here, Elias. It’s designed to self-replicate if threatened!"

Elias looked at the massive fiber-optic trunk cables connecting the server array directly to the mountain's high-power transmission antenna overhead.

"Then we don't wipe the data," Elias said, reaching into his pack and pulling out the custom signal-inverter circuit he had built in his shop days ago. "We overload the transmitter itself. We burn out the physical antenna."

Riley looked at the circuit, realizing his plan instantly. "If we feed a feedback loop back up the high-voltage lines, it will destroy the entire transmitter array—and the backup server along with it."

"Do it," Elias said, locking the inverter onto the main power bus bar.

Riley executed the feedback script. The purple glow of the server rapidly shifted to a blinding, erratic white. The countdown timer froze at 00:01:05.

A deep, deafening rumble shook the floor of the bunker as electrical arcs danced across the server racks. High above them on the mountain peak, the massive transmission tower burst into a shower of brilliant sparks as its main power transformers melted under the surge.

The terminal monitors shattered one by one, plunging the vault into quiet darkness.

The countdown clock went completely black. The local signal was destroyed.

Elias stepped back, looking at the smoking server racks. Oakhaven was finally clear of the dark frequency.

He looked over at Riley, who offered a tired, relieved smile. "The city is safe, Vance. The local node is dead."

Elias nodded as the first rays of morning light filtered through the open vault doorway. But deep down, as he glanced at the dead server racks, an uneasy feeling lingered in his chest.
