Omega and Midgarsomr - Possible XV origins

[Enkidoh]

Worth noting that FFVII and FFX actually do canonically share a universe.

I'd take that with one very big grain of salt though, as it's never been explicitly mentioned anywhere in the actual FFVII Compilation titles at all that it shares it's universe with FFX (in fact, the whole reason this idea is even considered was comments made by Shinra in FFX-2 about 'massive energy' inside Spira that could be potentially used as a power source), and Kitase and Nojima's tongue-in-cheek 'clarification' about it, showing that even they don't really take the concept that seriously (and seem to be amused at those who actually do - Shinra's comments were just a fanservice reference to FFVII without directly connecting FFX to it, just like here in FFXIV with things like the Crystal Tower and even the Ivalice raid, it was fanservice, nothing deeper).

Besides, despite the above vague FFX-2 reference to Mako energy, Spira and the Planet have entirely different metaphysical frameworks: if FFVII really was in FFX's universe, then why don't the dead require sending in FFVII for instance? Or why isn't there materia found in FFX? The two worlds are simply too different to logically exist in the same universe running under the same rules. Thus I'm taking Kitase and Nojima's comments as tongue-in-cheek at best and retconning at worst. But I digress...
