I hope she's not just an errand girl again, but... it seems so likely. But I forgot that there is more than one book, Maleficent could have just found one of them... but are they all connected in that way? I guess they could be.
I didn't include Yen Sid's only because there isn't any indication that a world is stored inside of it. Which links to my question above if all the books of prophecies are linked because in that case, I assume only one of the books hold the sleeping dandelions, that probably being Ava's.
This also makes Merlin's weird statements about "AWAKEN YOUR INNER POWER WITH THIS WINNE THE POOH BOOK", there's probably something else to it in that exchange. Other than unlocking a command board
It would certainly better if it would not be, but looking at other things this seems to be a flurry of parallels swung about, so that may be one too.
Well, the five copies held by the Foretellers
are derived/copied from the original one the Master of Masters held (or maybe still holds). However, copies
can diverge into something of their own depending on influences despite having the same origin while
still being connected.
We have already two seen two prominent instances in the KH series, one being a character and another being a world.
The character in question is Roxas, as he was created/born as a copy from elements of Sora, but developed into something of his own while
still being heavily connected to Sora. The same could also be applied to Naminé, Xion and possibly even Vanitas, although to different degrees.
The world in question is Space Paranoids/The Grid, that one being even outright described by Xemnas in DDD. Space Paranoids is a copy of The Grid and the Tron in one of them is different to the other, but they are
still somehow connected as Sora eventually managed to reach The Grid-Tron's/Rinzler's heart despite never having met him before, possibly due to his connection to Space Paranoids-Tron who despite diverging and developing into a different entity/person is
still somehow connected to The Grid-Tron/Rinzler.
Xemnas also speaks about that data can be copied. If you do the same with a magical book you get a similar result.
Thus, it
is possible that all of the five copies of the BoP are slightly different due to influence from the respective Foreteller that wielded it.
The sleeping Dandelions would most likely indeed be in Ava's copy though.
