Pfes-005 -

The drone played it.

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.”

PFES-005’s logic core churned. This was unsolicited, emotional, unscientific. It should have ignored the log and resumed its search for the black box.

Then it felt something new—a low, vibrating hum building in the deck plates. The same frequency as Engine Four’s resonance. The walls began to shimmer, not with heat, but with memory. Ghostly figures of crew members flickered past, reliving their final moments: a woman laughing over a spilled coffee, a man tightening a bolt, a child—no child had been on the manifest—tracing constellations on a viewport.

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.

Instead, it copied the file.

The drone calculated its options. Return to the salvage bay with the black box, mission complete. Or stay. Listen. Help.

“...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.

The Recurve never recovered the drone. But three months later, a deep-space relay picked up a faint, repeating signal from the Odysseus debris field. Not a distress call. Not data.

A voice—not from the slate, but from the air itself—whispered: “Help us finish.”

The drone paused. That was not in its programming—pausing without a directive. But PFES-005 had been in service for eleven years, three months, and seven days. Long enough for its heuristic core to develop what engineers called "ghost preference"—a tendency to follow curiosity over command.

Silence.

It was the sound of a child laughing, and a small, mechanical hum keeping time.

It thought of Dr. Thorne’s words: Remember.
