You know, Back Cover makes everyone believe that there is no traitor and that the MoM set the whole thing up. But we don't see the whole picture. Remember that BC was supposed to show us one side of the story, but people ignore what happened in X and Unchained X.

 

There are some reasons which lead me to the conclusion that there must be a traitor.

 

1. The one who "bears the sigil"

It's clear that if there is no traitor, this detail would be unnecessary. I doubt that it's meaningless.

 

2. Nightmare Chirithy

The sole existence of a dark Chirithy means that it can be traced back to someone whose heart belongs to the darkness. This Nightmare Chirithy seems to follow his own agenda as he collects Lux and don't want the player to know "the truth".

 

3. Ava vs Luxu

While Ava confronts Luxu, we see Gula talking to the player and Skuld about the lost page. It contains this passage:

 

"Unable to permit disharmony, you will be disappointed by fate, and lose sight of true strength. Misreading the truth, you will venture forth in secrecy..."

"And then with that one strike, a bell will toll for the final battle and the battle will begin at last, and the time shall be chosen"

 

It's worth noting that the scene changes back to Luxu and Ava after Gula said that. After that Luxu said the truth about the traitor to Ava and she attacks Luxu with "that one strike". This is heavy information because it gives us a concrete idea who the traitor could be.

 

 

So there must be a traitor after all. Who is it? According to the given information the traitor must

- bear the sigil (it does not necessarily mean the "X", it could be some other form of sigil, for example the Dream Eater symbol)

- disappointed by fate (this implies that the traitor had good intentions first, but was disappointed that everything will lead to a war)

- misreading the truth (this means that the one must have read the Book of Prophecies and made up his own interpretation)

- venture forth in secrecy (this means that the traitor has been plotting behind the scenes ever since he read the book)

 

 

This means that only the following persons can be the traitor:

- Ephemera

- Gula

- Ava

- Luxu

 

Why Ephemera? He is the one who wants to solve the "mysteries of the world". In the result he is interested in the book of prophecies and could have seen important passages of it at some point in the story. After this he was disappointed of the listed events and disappeared for quite some time. He is driven by curiosity which eventually leads to corruption by the darkness (the same pattern as Xehanort and Riku).

 

Why Gula? We know that Gula and Ava are good friends, maybe even more. Her reaction during the Luxu fight could indicate that the traitor is someone close to her. Gula is the only one who knows what is written in the Lost Page, so he could "misread the truth" about the traitor. He is also the first who collects Lux in order to summon Kingdom Hearts. The whole time he is someone who is secretly doing his own thing.

 

Why Ava? According to the book of prophecies the strike on Luxu started the conflict, which makes Ava theoretically the cause of the Keyblade War. Even if she doesn't fulfill the criteria for the traitor yet, there is a clear impression that her actions make things worse instead of better. Her conversation with Luxu makes her a suspicious candidate, although she has good intentions.

 

Why Luxu? He is the only one who didn't get a book of prophecies. So what if he took a look at one of these? Maybe he started to realize what the MoM's true intentions are. He is also the most obvious when it comes to the "sigil".

 

--------------------------------------------------------------------------------

 

By the way:

 

The X is often referred to as the sigil. In DDD Young Xehanort said that Sora has the "X" on his chest and they always knew where he is due to the X. During the Xemnas fight he said: "As your flesh bears the sigil, your name shall be known as that of a recusant". It's just a short sentence but it has very high significance now.

 

A recusant is someone who refuses to obey people who have authority. In the context of Back Cover, the one who bears the sigil (the traitor) is a recusant. This means the traitor refuses to accept the MoM's teachings or his vision of the future and tries to change it. In fact, it's not about light vs darkness anymore, it's more about destiny and changing events that are predetermined to happen.

 

Xehanort has a deterministic nature and believes everything is destined to happen, although he is curios if destiny can be changed. The answer for this lies in the Keyblade War, where "darkness prevail and light expire". In the end he wouldn't be disappointed if darkness won't prevail, because it's only about satisfying his curiosity. Sora would be the exact opposite, following his heart without any restrictions or boundaries. He doesn't let his life be determined by destiny, he forges his own destiny. This makes him somehow the biggest traitor of them all and he will actually succeed in changing the future. After all, Sora and Xehanort both come from Destinys Island.

Hmm, this is pretty concrete! A very solid theory! I am one of the many people who think that the Master Of Masters simply set this up in order to cause the Keyblade War, but seeing your post has made me think quite a bit! Ephemera does seem suspicious in the fact that he doesn't show for a lot of time during the events of X/Unchained X, and Gula is pretty mysterious, and he has that defiant air about him! Ava is the one I'd see as the unlikeliest to be the traitor, and Luxu, that guy's another mystery! Hopefully, more information about this shall be revealed with time! Oh, and we haven't even seen what Blaine is up to, so he may also have a hand in this!

 

It's curious how this whole thing about the traitor has been kept so closely under wraps! Odds are that by the very end of X/Unchained X/Union X, we'll finally have our answer, and perhaps we'll see something about this carry over into Kingdom Hearts III!

My problem with this theory is that xemnas could've been referring to xehanort,

and since unchained X took place before BBS (where the whole story started) xehanort wasn't even mentioned. However, since luxu has the keyblade xehanort is known to wield, I have a theory that luxu and xehanort are associated, but not the same person.

That could be a reasonable hypothesis! All we are sure of is that Luxu came to pass on No Name to someone who'd end up passing it to Xehanort, that much I know!

My problem with this theory is that xemnas could've been referring to xehanort,

And who is Xehanort referring to? The Book of Prophecies. He must have more knowledge about the past than it seems and the fact that Xehanort says that "Destiny is never left to chance" makes me believe that he must have read it.

 

MoM thinks that changing the future is impossible and Xehanort does the same, probably because he is referring to MoM and the book of prophecies. Consequently the authority that a recusant (Sora) is not obeying is the MoM.

 

I wonder now, since Sora was never supposed to wield a keyblade, if this is something destiny decided or if it's a deviation.

But here's the thing. He couldn't have possibly known about the book of prophecies, since he was only told about the keyblade war, unless he was told about it by someone else, or had managed to get one, but considering the only complete copy is in the possesion of the MoM, it doesn't make sense how he could've known about the events.

Xehanort says in the KH3 trailer: "On that land darkness will prevail and light expire"

 

Where did he get that line?

 

In any case, Xehanort is someone who is convinced that destiny is something unchangeable and his proof is the book of prophecies.

But the million dollar question is how did he get one, if he didn't have any knowledge?

Who says that he didn't have knowledge at all? Maybe it's just incomplete knowledge and he wanted to see how things will unfold in the future. And it's not like the book of prophecies is the only source Xehanort is referring to. For example, the X Blade definitely isn't mentioned in the book, but interestingly he knows a lot about it.

I don't know about that, I guess well just wait and see.
