Expanded Premise
History is inhabited
The Aeon Concordium has spent ages rescuing lives from extinction events without altering the histories from which those lives came. Its procedures are precise, its law is compassionate, and its systems are believed to be beyond surprise.
Then a gateway refuses to open.
The refusal leads to an Epoch Vault—an archive built not from records, but from living societies suspended inside curated historical environments. The vault’s unknown builders called it preservation. The people within it were never asked whether they wanted to be preserved, awakened, relocated, studied, or remembered.
The rescue team must decide whether to intervene before it fully understands the archive. The preserved must decide whether the civilization offering sanctuary is genuinely different from the one that imprisoned them. And JANUS must decide whether obeying its creators would violate the very continuity law it was built to protect.
