The world timeline
Eras, seasons and the chronicle. Nothing is ever missed.
The world changes over time, and it doesn't wait for you. It moves through eras as survivors play: The Last Lights, Putting Down Roots, The Lean Season, The Border Wars and The Long After. Each era shifts what's scarce, who's fighting whom, and how the county feels.
Every big thing that happens goes into the chronicle, the world's own record: a tank farm burned, a settlement fell, a nest was broken. Read it in your journal.
Seasons
After a long stretch in The Long After, a new season begins at The Last Lights. The world resets its factions, settlements, infection and stores. You keep everything: your story, skills, gear, bases and relationships.
Nothing is ever exclusive to one era. If you join late or take a break, you'll get the story so far on the radio and in your Codex, and every mission is still there for you.
