On April 3rd, 2199, at 02:17 local time, Marcus Oduya-Swanson, a freelance equipment dealer, called his business partner from what he described as "somewhere past the Joliet marker." He said his vehicle had broken down. He said he had been driving through the Indiana badlands and missed a turn. He sounded tired but coherent.

He described his surroundings: flat terrain, no lights, the smell of old industry. His partner told him to stay with the vehicle and that a recovery service would be dispatched. Oduya-Swanson agreed. Then he stopped talking. The line did not disconnect. For forty minutes and fourteen seconds, the call remained open. There was no breathing. No background noise. No wind. No engine sound. No static. Absolute silence, as if the microphone had been placed in a vacuum.

At 02:57, the call ended. Not disconnected by either party — the network logged it as a connection timeout. The recovery service found his vehicle at the coordinates his comm device had last pinged. The vehicle was intact, engine cold, doors closed but unlocked. His personal effects were on the passenger seat: wallet, comm device, a half-eaten protein bar. The driver's seat was adjusted to his body dimensions. There were no tracks leading away from the vehicle in any direction. The ground was soft enough to hold prints. There were none.

Marcus Oduya-Swanson has not been found. His comm device's audio log for the forty minutes of silence contains exactly what the partner heard: nothing. Not low-level noise. Not ambient sound below human perception. The waveform is a flat line. No microphone in operating condition produces a flat line. Even in a sealed room, there is thermal noise. For forty minutes, his phone recorded the sound of nothing at all.
