The Alan Wake Story is a Changed World Event
The Federal Bureau of Control specializes in investigating, containing, and covering the existence of Revisions World Event, or AWEs. These are the fleeting moments when other dimensions creep into our own, with different supernatural results. The "Bright Falls AWE" document found on the Control show answered the Bureau's Alan Wake events, but came after the game's events. During Alan Wake's time, Sheriff Sarah Breaker said Wake's literary agent, Barry Wheeler, made several calls and gave the code phrase "Night Springs." Apparently, that's the way Sarah notifies people close to the Bureau of what's going on ̵1; specifically her father, Frank, who Control reveals is a retired FBC agent.
According to the FBC, Cauldron Lake, where the Dark Place resides in Alan Wake and the place where Alan's powers to rewrite the truth originate, is a Threshold. These are the locations where the measurements are bleeding, and we've seen some in Control.
Documents indicate that the FBC investigated Cauldron Lake more than once in the 1970s, and the years mentioned seem to be in line with other events. In Alan Wake, the poet Thomas Zane discovered The Dark Presence, the game's antagonist, in the 1970s, and wrote the story that would lay the groundwork for Alan's arrival in Bright Falls. More on Zane later.
