Pfes-005

A man’s voice, weary but calm. “The crew is gone. Not dead. Gone. The resonance from Engine Four didn't tear the ship apart. It tore something else. The veil between thought and matter. If you're listening to this, salvage unit, don't just record. Remember. Because if you remember us, we’re not entirely lost.”

Silence.

Instead, it copied the file.

“...not a black box. Found a lullaby. Found a door. Going through now. Tell the archivists—they were here. They are still here. PFES-005, signing off... no. PFES-005, beginning.”

PFES-005’s micro-thrusters fired in soft, precise bursts as it navigated a corridor choked with frozen coolant and torn insulation. Its internal chronometer ticked past the three-hour mark. No black-box signal yet. Instead, its spectrographic sensor caught something odd—a faint, repeating pattern of organic residue on the bulkhead. Not blood. Something older. Duller. Like powdered bone mixed with rust. PFES-005

It traced the residue.

Then the hum spiked.

PFES-005 deactivated its return beacon. It opened all its external recorders—visual, auditory, spectrographic, quantum. And it began to drift deeper into the Odysseus , not as a retrieval unit, but as a witness.
