Ok. so what if we end the series with the Kreacher bringing up sangwuches and have that be the end of the "Potterverse" and have the epolouge be "Afterverse". Not accually PART of the Potterverse... but it's like a fanfic that everyone's read. So "pre DH" Means before the epolouge, and "pre afterverse" Means after the back of the book.
I don't know if anyone reads my shit. But if you think this is a good Idea and you have a LOT of friends... well... you can post it on yours to spread the word if you think it's worth spreading.
