Generation Loss

Noa Stern has been Archivist of the Ardent for six years. She arrives at the forward section's Sub-Level 3 before the ship's dawn cycle comes fully online, when the archive is quiet in ways that are not just auditory - more itself. She looks at the Hull Ledger with its thousands of names, every person who has been born on the Ardent and died on the Ardent in two hundred years of voyage. She maintains the physical record: four thousand square meters of shelving, cabinet, and sealed-environment vault containing material from the founding generation that has never been fully digitized. The restoration project was commissioned eight weeks earlier by the Council of Stewards: restore all QD-14 format data cartridges before further degradation renders the task impossible.
It's not an unusual request. Media deteriorates. Noa has done restoration projects every year since her appointment. Except this one is different. On day three, she finds a palimpsest - a cartridge that contains two layers of writing. The surface layer: official technical records from voyage year one, exactly what the catalog describes. The layer beneath: something else. Not completely different - many passages are identical.
But different enough that the differences are not accidents. The founding documents have been deliberately altered.
