What is the fnaf rebornica AU!?! (a guidebook)

( note: temporary cover )

Are you a newer FNAF fan?
Are you wondering 'who in the hell is Vincent and why does he like toast?'
Are you wondering why in certain interpretations of Phone Guy, he as a literal phone for his head?
THEN THIS BOOK IS FOR YOU!

Note: I have been in the fandom since 2014 and know a lot about this AU but I might get some info wrong, I am doing this by myself for the most part after all.
