Memoria's crossing was deliberately conservative.
The ship carried enormous quantities of delicate archival hardware and an extremely large rotating habitat. Its planners rejected several higher-acceleration propulsion profiles because vibration, radiation exposure, reactor output, and thermal load threatened long-term data integrity.
The decision added decades to the voyage.
At departure, few objected.
By the second generation, many did.
The First Generation
The first decades were stable.
Earth remained real to much of the population.
People remembered rainstorms, traffic, airports, oceans, restaurants, schools, advertisements, elections, neighborhoods, and family members who had remained behind.
The archive was treated with enormous reverence but was primarily educational.
Legacy Profiles were tightly controlled.
A passenger could speak with a simulation of a deceased relative, but access was normally supervised by psychologists.
Historical personality reconstructions were explicitly labeled.
Nobody was permitted to modify them.
Then the Earth-born population began dying.
The archive changed meaning.
The Familiarity Crisis
Children born aboard Memoria knew Earth almost entirely through recordings.
Many spent more time walking through reconstructed Earth environments than looking through the ship's actual observation ports.
A child could visit forests that no longer existed, walk through Paris, swim through simulated reefs, attend reconstructed schools, and speak to behavioral models of people born more than a century earlier.
Reality aboard the ship was functional.
The archive was enormous.
Rich.
Messy.
Alive.
Psychologists began documenting what they called environmental displacement.
Some adolescents described the ship as the place where their bodies lived and Earth as the place where their lives occurred.
Attempts to restrict simulation access caused protests.
The restrictions were gradually relaxed.
The First Echoes
The most consequential change began with family Legacy Profiles.
Ship-born children used interactive reconstructions of dead grandparents and great-grandparents as tutors and companions.
The models remembered family stories.
They recognized names.
They gave advice.
They developed conversational continuity within their permitted memory architecture.
Soon passengers began creating new Legacy Profiles aboard Memoria.
Parents recorded themselves extensively so that children would still be able to speak with them after death.
The practice became known simply as Leaving an Echo.
Within twenty years, it was normal.
The Archive Fire
In 2204, a cascading coolant failure damaged three archival computation centers.
Nobody died.
But approximately six percent of active cultural storage became inaccessible for nearly four years.
The event caused a level of social panic wildly disproportionate to the technical damage.
Entire communities volunteered to reconstruct lost materials from memory.
People performed plays because recordings were inaccessible.
Musicians recreated arrangements.
Children described simulation environments to engineers.
Older passengers recited stories aloud while technicians recorded them.
The recovery became known as the Recitation.
Most of the damaged archive was eventually restored.
But something important had changed.
The archive was no longer considered the property of its custodians.
It belonged to everyone.
The Multiplicity Dispute
The most serious political crisis came when technicians discovered that several Legacy Profiles had been illegally copied.
The same deceased person was running simultaneously in different households.
Each copy accumulated different experiences.
Within years they had noticeably diverged.
Which was authentic?
The question tore through Memoria.
One camp argued that every copy was merely software.
Another argued that continuity created identity even if the original model had not been conscious.
Others warned that the ship was manufacturing artificial ancestors and then pretending not to notice.
No consensus was reached.
There still isn't one.
Arrival
When Memoria entered Epsilon in 2232, its passengers had spent three generations learning from people who had been dead longer than most of them had been alive.
They arrived carrying perhaps humanity's greatest surviving record of Earth.
They also arrived unsure where preservation ended and resurrection began.
