The vibration in Cell 17 was the source. It was microscopic—a fraction of a millimeter of imbalance in the cell’s internal lining, caused by a gradual settling of the refractory brick over decades of thermal cycling. But that tiny imbalance was enough. It transmitted a low-frequency oscillation through the floor slab, which traveled through the building’s steel structure, resonating at different frequencies in different pieces of equipment.

Elara didn’t answer. She walked out of the control room and into the cavernous main hall, where the reduction cells stretched in two long rows, each one a concrete-lined pit filled with molten electrolyte at 960 degrees Celsius. The heat hit her like a wall, but she barely noticed. She walked to Cell 17—the oldest cell in the line, the one her grandfather had helped install in 1965.
