Dr. Aris Thorne, the senior technician, had tried everything. He’d cleaned the brushes, balanced the buckets, whispered prayers into its vent. Nothing worked. The machine would run for forty minutes, then seize with a digital whine, flashing the error code: Rotor imbalance. Service required.

The rotor spun up. 1,000. 5,000. 10,000. The hum deepened, smoothed, became a purr. The imbalance error did not appear. The vibration was gone. Greta was silent as a sleeping cat.

He didn’t have diamond paste. He had toothpaste and a leather strop from his straight razor at home.
