Shared chronology

The known order of Project Zero, Submine, and the distant Zenith era.

The surviving record places the major chapters of the shared universe in the following order:

Project Zero

Project Zero precedes the other works and includes early appearances of N1RO, among other figures.

Submine

The Submine era saw GPP discover Tserin and the GPP reactor explosion create Shard-T. Nanapo was associated with GPP during this period. Crystalite carries connections to the Submine project and its later history.

Project Zenith

Far later, on another world, Mia leads Zenith (organization) and begins rebuilding through industry. The world already contains traces of earlier construction. A.R.C., associated with N1RO, arrives after the start of Mia's mission.

The intervening years

The exact interval between eras, the fate of older institutions, and the history of the civilization that once occupied Zenith's world are not known.
