The high-voltage feed isolation substation was built into the solid granite of the southern foundation wall, forty yards from the flooded utility cellar.
Here, the air was free of kerosene smoke, but it carried an electric charge so dense that the hair on Mara’s forearms stood straight out from her skin. Overhead, three copper busbars as thick as fence posts ran from the main turbine hall into a bank of oil-filled circuit breakers, vibrating with a deep, bone-shaking sixty-cycle hum that buzzed inside her skull.
On the front of the slate switchboard, three six-foot wooden levers—the primary disconnects for the regional extraction grid—stood upright, their massive copper knife-blades seated deep inside spring-loaded brass jaws.
Above the levers hung an enameled steel placard, its black stencil lettering chipped and yellowed: REGIONAL EXTRACTION TRUNK — CENTRAL DISTRIBUTION.
Since 2016, this switchboard had been the beating heart of Silas Venn’s empire. Through these blades had flowed the harvested continuity of thousands of men, women, and children, converted into raw electrical coherence to power the electrified fences, the searchlight towers, and the warded halls of Haven Compound.
Tessa knelt before a low terminal cabinet beside the board, her multimeter probes clamped across a bank of heavy ceramic resistors.
