..I actually like the idea of Darnus becoming Odin, in some form or another. The one guy who is hell-bent on destroying Primals, becoming one, or having his essence transferred into what was once Odin, sealed up inside Dalamud.

His own words said, though not quote for quote, that what good is a world bereft of the crystal's light, when talking about how the empire is bent on destroying all primals and the rest of eozrea in general.

Which, may just be a typo of some sort, or another meaning in it.. if Darnus is so focused on destroying the Primals and life in general "purfication' as it were, but is still embracing 'the crystal' in whatever form its taking in this game.. does that mean that the Primals, or the Dieities themselves, are not of the Crystal but a different source?

The 'Crystal' as it were, has always been the origin source for everything, well typyically, in the FF universe. But it almost seems as though in this case the Crystal and the 12/primals arent actually connected, but remain separate idenities..
