Oh, I like this one... "crossroads of fate" indeed...
And, another FFVIIR inspired one, which is going to get lots of groaning (none the less because I myself actively dismissed such ideas in the past), but hear me out:
FFVII's Planet is the Source Hydaelyn in the far far future! And based on what evidence? The appearence of none other than the Enterprise in the skies over the Cetra civilization, so by extension, we are all Cetra! (okay that particular scene was just a Shinra propaganda video... but it can be infered that the Shinra's artistic interpretations of what the Cetra were like were based on Ifalna's information, given the Cetra shown in that scene match the mural Aeris drew on the wall of her cell as a child... so the appearence of Cid nan Garlond's Enterprise from Hydaelyn in that video must mean that Hydaelyn=The Planet is also true right?
And hey, both planets have a Lifestream and materia! ;)

And that is not also taking into account that FFVII's universe but not world and FFX's Spira are supposedly in the same universe, but that was never really confirmed as actual canon... so.... ;)
Yes it's complete and totally darksteelfoil, but.... these are strange times indeed we live in so... ;)
