I know we hear this one a lot, but think about it. We ARE The darkness. Not because of all the other things in the game. The biggest piece of evidence is YOU. Think about it. 1. Our Character has NO say in anything. Almost if they're expected to do whatever task. 2. Your guardian has little to no objection for anything in the entire game. Sure, this could be a flaw, but what if it isn't? 3 . When we were resurrected, The Traveller/Speaker could've done anything they wanted to us, or more specifically, ghosts. Each guardian could have free will to a certain point. So pretty much my theory is that all guardians are pretty much indoctrinated from their first awakening.
