The ´´shooting star´´ or as sometimes called a meteor and that fact that this game is a story prequel for rejuvenation. Plus dont tell me you have all forgotten about the weird story from fortune teller lady in the neo city. She said that she saw a future where we are not and that there will be an apocaliptic event and I qoute " And Beaded hope breaks apart upon the tattered stones of a city forced to live up to its name again." This whole story is saying that, if we are not present in the story, Lin will win and everything that everybody has done will be undone. And as I said about the meteor and plus the story that we know from both games there is a big chance of Arceus shenanigans.
(( P.S. What if that Man/Woman/Idontknowwhat on the card is the person who talked to us in the sancuary and at the end of version 18?))
Thank you for your time
Edit: Plus the beaded hope could stand for Victoria, if that is true then is confirmed that the city was rebuild ( Like we as players did in our run of the game and as our wallets know) and then again (thanks to Lin) destroyed.
