Origins

Don't attack me for having an opinion. Feel free to talk about your own, but don't shove it in people's faces, or tell them random things with no context or proof.
Everyone seems to have shared their theory, so I'll share mine. I should have done this three years ago but oh well. I tried to keep it short, and I'm happy to answer any questions you have.
The chapters are labelled accordingly, and any other theories mentioned are at the end if you want to skip to them.
The only games that I don't mention are FNaF World and Help Wanted, so don't get your hopes up about those two.
