Speculah about Foretellers,Dream World and the Box

Update:Foretellers travelling to (supposedly) a Worldline of a different time axis to escape the end of the world confirmed by Nomura,but he never mentioned the exact method of time travel.
So thinking about it,it's not hard to figure out where were the Foretellers preserved and why MoM doesn't want the box to be opened until Luxu summons all 5 Foretellers from their sleep,the current information known to us makes it possible to make a conjecture regarding these 2 questions.
In Secret Report 12 it's revealed that the Foretellers were not dead but simply put to sleep stasis until the future written in the BoP comes to pass.the question is where have they been preserved during the period where they are put in stasis,considering the wording of they having to be "awakened" and "summoned",the answer is simple:they've been thrown into a dream world to be preserved so they'll survive the end of the world during the Age of Fairytales as part of MoM's overarching scenario/program in the case they failed their trial of overcoming the future(as it's not explicitly written that the Foretellers were the traitors written in the Lost Page,they have a chance to overturn the prophecy of the Lost Page that was meant for them which is what MoM wanted to observe,however the Foretellers hypothetically overcoming the prophecy would not prevent the apocalypse from happening in the end as anyone else can fulfill the prophecy of the Lost Page due to the prophecy not naming the traitor).
Lost Master Epilogue indicates that Luxu needs the black box to awaken the Foretellers as the box is with him when 4 out of the 5 Foretellers was summoned so it seems the contents of the box is needed to access the dream world the 5 are preserved in(the Power of Waking needs a catalyst to work,be it a person or a world to access the Worldline of Sleep) which means the contents of the box is conjuring the dream world and that's why Maleficent got the mistaken impression that the Book of Prophecies is inside the box as they have the same power of conjuring worlds?(BoP having the same symbol as Superbia's piece seems to point a connection between the book and the missing sin)
If that's the case opening the box which Sugita doesn't want happening until the determined time would awaken the contents therefore causing the dream world to collapse and summoning all 5 Foretellers back to the worldline of reality,at the same time the contents being awakened even without the box being unsealed would have the same consenquence which means KH3 Ephemera was trying to awaken the contents of the box to summon the Foretellers so the 7 Guardians would win without Xehanort repairing the X-Blade.
On another note:
-Ava isn't summoned back to the worldline of reality because she's the only Foreteller who did her task correctly so she's still in the dream world?
-The box has the name XSuper grafted on it which indicates the contents of what is sealed inside the box is associated with the sin of Pride,people speculated MoM is the one associated with Superbia because of his "you 6 with me equals 7" statement in Back Cover and because Pride is the only sin left vacant among the 7 sins but the problem is he's already associated with God what with him being all knowing but not omniscient,testing the Foretellers with the trial of defying fate by letting them create the Unions and also his all reaching plan throughout the series plus if he really was associated with pride then he would try to overthrow the future instead of just accepting and letting it happen which isn't something someone associated with the sin of pride would do so he's not associated with pride.Incidentally considering his association with God,his statement of "you 6 with me equals 7" would have the meaning of God and 6 sins so 1 sin is missing from the sins which implies the existence of a missing apprentice?
-The chess piece that represents Superbia in the KH3 epilogue which also appears in X,KHUX,and Back Cover is a Heart with angel and devil wings which indicates the character that represents Superbia is also associated with Lucifer,so the theoretical missing apprentice attempted a rebellion against MoM just like Lucifer with God but also failed like the former and got sealed away in another realm?(possibly the same dream world the Foretellers are preserved?).
