"Throw wide the gates, that we may pass" [SHB speculation]

[Nalien]

I have a theory... What if when he says "we", he means himself AND the WoL. If it truly is G'raha, it could be that he is still in our Crystal Tower. He said he will stay inside to help open the gates one day.

His exact words;


Not sure he is capable of helping anyone open it from inside stasis, though perhaps other localizations offer more clarity on that.

My current theory, given dimensional travel is confirmed, time travel is almost certainly hinted at, along with "History must be rewritten", is that the people of Crystarium are the ones to rival the Allagans in knowledge. Crystal Tower has been sent into the past of the First specifically to allow for that civilization to build up around it and throw wide the gates... G'raha then struts out and will probably be very confused as to why we're there waiting for him... Although given he may be Enigma, perhaps it opened awhile back and he is now trying to reach out to us...

I almost wonder if the Tower ever even sunk following Xandes Calamity, now... I mean, if history must be rewritten...

• Xandes Calamity happens; Send the Tower into the future so it appears shortly after Dalamud fell.
• We then open it up, clear that whole mess, and it's resealed. All under the misguided assumption that it merely slept beneath the earth all that time...
• Come 5.0, it's then sent back into the past, right after (or before?) it vanished following Xandes Calamity. Now, from there, taking advantage of the energy released from the Calamity, and weakening of the barriers between Shards that Calamities entail, it is warped to the First.
• It now no longer exists on Eorzea, as history recorded.
• With the Towers future now sitting in the past of the First, with an as yet unknown portion of that history now being in perpetual daylight due to the Flood of Light, it now has ample fuel supplies (recall that it originally collected solar energies to power the Allagans civilization).
• Fully powered, and with twice the expected output due to a never ending day on the First, the Tower can now fulfill it's original purpose; Opening a Voidgate.
• At some point (in 5.0 or the 5.x series), we use the Tower to open a "Void"gate between the First and Source, one so massive that the Tower itself appears back on the Source as if nothing ever happened.
• Free movement between First and Source is now possible. We already have confirmation this is possible, given the Voidgate allowed non-Echo users to travel between Source and Thirteenth.
