Spoiler ShowI did not understand, the campaign remake was originally AU in relation to the original. Well, here are extended events, new characters that were not in the original and which could not be there, and that’s all even without the intervention of these spirits. Even the clothes on the heroes are different, not the same as in the original and in their compilations. It may be that Seferot was defeated by Cloud in "Advent Children" and moved to another alternative universe to fulfill all his goals there. This is, of course, half the theory, but the plot twists are haunting me, and I want someone to clarify what happened.
By the way, how Aerith is dressed in the FF7 Crisis Core and Original Game https://images-na.ssl-images-amazon.com/images/I/51-A7a05cEL._AC_SX425_.jpg and how she is dressed in the FF7R https://media.kg-portal.ru/games/f/finalfantasy7remake/production/finalfantasy7remake_5.jpg, (Of course, many will say that I wrote nonsense, but do not forget that Nomura, the person who, was involved in Final Fantasy 7 remake, made the whole episode In KH why Mickey lost his jacket.) it seems to me that the scriptwriters intentionally made FF7R AU, in order not to touch the original, but to introduce new events in remake.
