Nuclear Apocalypse

This new timeline begins in the year 2046. The Anchor cannot speak vocally. Instead, they communicate via TIP, a Telepathic Interface Protocol. Their text shows up on the screen in green, while TERI’s messages (again encompassing the totality of the viewer chat from 2019) appear in TERI’s blue.

World 3

Totalitarian State

In this alternate 2049 timeline, the Anchor, Darling, inhabits the bunker alongside a second AI entity known as Tarry. Together, they attempt to remain hidden from the Veilers--agents of the totalitarian regime in power in this world--through Tarry’s calibration, for which 2019 participation is crucial.

World 4

Overpopulation

In this new timeline, also in 2049, the world has been ravaged by overpopulation. As such, there are many potential Anchors in the bunker. An unidentified, robotic voice — presumably a version of TERI — acts as a gameshow host, directing the many potential Anchors through questions that determine their eligibility.
