The power bar gallery beneath Central Dynamo Station was sixty feet wide and lined with glazed fine china insulators.
Through the center of the gallery ran the main ice-cold feeder lines, shrouded in stainless steel empty pocket jackets frosted white with condensing air.
Even twenty feet away from the padded channels, the surrounding physical air was distinctly unsettling.
Giles Croft walked down the center of the gallery. His wooden ruler was held firmly in his right hand.
The brass tips of his work boots clicked rhythmically on the concrete floor.
With every step, his belt buckle and iron tool loops gave a faint, persistent magnetic tug toward the left-hand wall.
Beside him, Toby Karr held a portable high-speed galvanometer. He watched the mid-air needle quiver against the etched brass scale.
‘Magnetic field intensity is eight hundred gauss right here on the walkway, Lord Giles,’ Toby reported. That kept his distance from the feeder channel.
