Can someone explain the dream thing in the latest FFX thing? It's really confusing me.
My time to shine!
So, like the Fayth kid said, 1000 years ago Bevelle and Zanarkand were at war, and from the get-go Bevelle had way more firepower and Zanarkand had no chance. But even back then Zanarkand had summoners (I don't remember if Bevelle and rest of Spira did, but that's not really relevant), and they wanted to preserve the "Zanarkand as it was before the war".
Now, we were told way back in Besaid that "fayth" are people who willingly trapped themselves in stone, essentially living forever. These are the things Yuna prays to in every temple, and therefore forms a "contract", allowing her to call Aeons, souls of the fayth.
So, if just one fayth can summon god-beasts like Rihanna, Seymour's Satan-Aeon and Nicki Minaj, imagine what hundreds of fayth working together can do.
Well, in Zanarkand's case, hundreds of summoners and civilians became fayth together to summon memory of Zanarkand, basically making a back-up version of the entire city and it's thousands of people.
And then thousand years passed, and nobody ever knew that this "dream of the fayth" existed, because how could they? How could you access data inside external hard drive in a world where computers don't exist?
But like Woolie caught on, all of this doesn't make sense just yet. Titus managed to "escape" this dream Zanarkand by getting sucked out of it by Sin, but what about Sin itself? Where did it originally come from? How can Sin move between Spira (reality) and Zanarkand (Dream)? How did Jecht originally manage to leave Zanarkand? And perhaps the most interesting question: If Auron is originally from Spira, how did he get IN dream Zanarkand after defeating Sin with Braska and Jecht?
Well, those are spoilers that may be revealed later.
