The logbook on the orbiting command ship updated automatically, its final entry stark and indifferent.

Then, the beacon flickered.

“…mission parameters are clear…” whispered one. “…Kaelen, you idiot, turn back…” hissed another, in his own voice. “…the probe never crashed…” droned a third, in the flat tone of his former commander.

No, not stopped. It had changed. It was no longer a passive drone. It was… listening. Kaelen felt it as a pressure differential in his ears, a subtle pull towards the Chasm’s heart. He drew the long, slender emitter wand from its holster on his thigh and slotted it into the cannon’s port. The weapon hummed to life, a high-pitched whine that was the MSBD’s active sonar, painting the invisible world in sound.

The logbook entry was simple, almost boring.

The effect was immediate and catastrophic. The sound cannon didn't produce a “blast.” It produced an anti-sound . A perfect, mirror-image wave of silence that expanded from the emitter in a translucent, rippling sphere. Where it touched the whispering voices, they were erased. Not silenced— un-existed . The dissonant chord collapsed into a single, pure note of negation.

The drop pod hissed open, releasing a cloud of frigid air. The Chasm wasn't a chasm in the geological sense. It was a wound in reality, a scar left by a failed Faster-Than-Light drive test a century ago. A mile-wide tear in the earth where physics went to sulk. And from that tear, a perpetual, low-frequency hum droned on, a sound that felt like a grey toothache.

He tapped it. It stabilized. He took three more steps. It flickered again, then winked out. Dead. Kaelen stopped. A cold trickle of sweat traced his spine. He looked at the MSBD 008 on his chest. Its power indicator was a steady, reassuring green. But the silence… it was wrong.
