The Dark Divinity 3.0

[Belhi]

Only this is not true either.

In-game, both Bahamut and Odin are referred to as Eikons (well, Bahamut is actually referred to as an "Elder-Primal," but he is often put in the same category as Odin). Bahamut was confirmed to be summoned by the thousands of captive dragons that were being tortured by the Allagans within Dalamud, and Odin (who was explicitly referred to as a Eikon), has been confirmed to be summoned by his sword, Zantetsuken, using a similar method to the Extreme Primal summonings for Titan, Ifrit, Garuda, and the normal Primal summonings of Shiva and Thordan. The sword possesses a host and refashions Odin's body. Having followers is not required. You just need a body to snatch.

Technically, though, your theory is still possible if we consider the real Odin and the real Bahamut. It's possible that the little midget in Minfilia's office was not referring to the Odin or Bahamut we fought, but the original beings that those primals were made to look like. It's an interesting idea made more so by the fact that the he explicitly singles out Odin. It would seem to imply that Odin is still alive somewhere, which is possible given that we don't know what actually happened to Odin's true body.

Personally, I think it's a bit of a stretch. It is more likely that this all just falls to a simple matter of the translation of the in-game text falling flat, especially given what the Dev's have stated on the subject in the Q&A, but it is an interesting idea. It would be pretty cool if the real Odin was still kicking out there somewhere.

Actually the main difference between thinks we know are Primals and Eikons (mainly Odin) is that Odin requires no worshipers. Odin's origin is very different to what we have heard from other primals. Koji Fox, in an interview I think, said that Odin was a warrior from the north who came south to protect Urth, who was at the time an enemy of Allag. To try and do this he took up a cursed blade that turned him into the Odin, the Dark Divinity. Id say its safe to say the original Odin is at least physically long dead.

Now firstly this is a primal/eikon with no worshippers to sustain it. Bahamut had thousands of worshipers in stasis sustaining him.

Secondly, is that the Odin we have now seems to retain its original identity and purpose even though it has switched bodies multiple times.

Thirdly, the story seems to suggest it was an artefact, not a ritual that originally created the Odin the Eikon.

Also I don't think they mentioned Bahamut being an Eikon in the new quests. He is very much a Primal in the same vain as Ifrit or Titan, just more powerful.

Now the interesting thing will be to see what the deal is with the Warring Triad. Unless they have worshippers stuck in vats somewhere it seems likely their worshipers died out long ago too. This again would suggest there is a difference with them.
