The NAJ-1501 was not a weapon, an engine, or a sensor. It was a librarian. A quantum storage array capable of holding the entire genetic, cultural, and historical legacy of the lost colony on Kepler-442b. The Manual —a battered, water-stained datapad they’d found in the salvage—was supposed to be their key.

The hum of the machine changed pitch. Deeper. Hungrier.

“Note 12a,” she whispered. “In the event of thermal runaway, the NAJ-1501 will initiate a self-preservation subroutine. Subsection 4: The unit may repurpose ambient biological mass as a coolant medium.”

They weren’t salvaging the archive anymore.

“Page forty-seven,” Rios said, wiping grease from his brow. “Says here: ‘To initiate core defragmentation, the ambient temperature must not exceed 2 Kelvin above absolute zero. Failure to comply will result in irreversible quantum decoherence.’ ”

The NAJ-1501 was their only bargaining chip. The colonial remnants back in Sol system would pay a fortune for intact memory. But the unit had been damaged in the asteroid field. Its cooling loops were shot. Every hour, it leaked a little more heat, a little more of humanity’s last hope.

The Manual slipped from her fingers. On the display, a new message blinked to life, written in the machine’s own cold, efficient script:
