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!
