(Lenne's, the other fayth). Borrowing from classic sci-fi plots I can imagine here he used "the dark side of the force" to create Sin, an extremely powerful but evil Aeon (violence incarnate as Lulu says). and then got trapped into it, loosing all his free will and being just a summoning "robot".

why are you guys so sure Yu Yevon has anything to do with Dream Zanarkand ? Was in Final Fantasy X Ultimania Omega guide ?
I got the impression that Bahamut's and the other Aeons fayth, plus the Dream Zanarkand fayth are AGAINST Yu Yevon and Bevelle. They do not agree with the Yevon cult scheme and they provide Aeons for the Spira people to fight Sin. "We are not a tool of Yevon" says the unsent summoner to Yuna, remember ?

Hence my conclusion that Yu Yevon somehow betrayed the Dream Zanarkand fayth, created Sin and got together with Bevelle against their wishes. He leaves Dream Zanarkand alone because, as you say, he has no free will anymore. But when Braska takes him/ Sin there he attacks Dream Zanarkand just as he/Sin attack everything else..

On Sin needing to "feed": Mindless killing is repugnant to me so maybe I'm trying to stretch the game plot a little, but think about it : A person's death creates the most powerful Aeon after Sin, the Final Aeon. Is it too much of a leap to think that the thousands of deaths give strength to Sin ? Perhaps Sin needs that many deaths because those are not offered willingly like the Final Aeon's is.
I'm going to be fairly blunt: your theory has no basis in fact. All of your ideas are based upon fundamental misconceptions regarding the FFX mythos; in short, they are contradicted by the very source material you seek to use.

Yu Yevon, as I've tried to make clear, is not a "cruel monster." Cruelty implies intent, which goes beyond what Yu Yevon can posess. He is the embodiment of Summoning, and that is all. There is nothing else, good or bad, there.

Sin should not really be compared to the power of "other Aeons" because Sin is not an Aeon. Sin, as repeatedly demonstrated, is a shell. It is armor that, for whatever reason, is given to a kind of absolute destruction. Sin has nothing to do with the Fayth; it exists to shelter Yu Yevon during the process of Summoning the Dreams of the Fayth. Again, let me reiterate: Sin is not a "powerful, evil Aeon." It is an armor that, as constituted, realizes itself in destruction.

Yu Yevon, without question, Summons Dream Zanarkand. This is directly stated in the game by the Bahamut Fayth.

Fayth: Yes. A war between Zanarkand and Bevelle. Bevelle's machina
assured their victory from the start. Spira had never seen such power.
The summoners of Zanarkand didn't stand a chance. Zanarkand was doomed
to oblivion. That's why we tried to save it-if only in a memory.


Tidus: What did you do?

Fayth: The remaining summoners and the townspeople that survived the
war... They all became fayth-fayth for the summoning.

Tidus: The summoning... You mean Sin?

Fayth: No. I mean this place. A Zanarkand that never sleeps.

Tidus: What?

Fayth: The dreams of the fayth summoned the memories of the city. They
summoned all the buildings, all the people who lived there.


Tidus: The people... What, they're all dreams? Me, too?

Fayth: Yes, you're a dream of the fayth. You, your father, your mother,
everyone. All dreams.
And if the fayth stop dreaming...
Yu Yevon's purpose in Summoning Dream Zanarkand, as stated, is to preserve the memory of Zanarkand. It could not win the Machina War with Bevelle, and thus was doomed. However, in Summoning the dream city, a real Zanarkand could continue to exist.

The Fayth, including the Bahamut Fayth, do wish to be free of Yu Yevon's Summoning. They're tired of Dreaming.

Tidus: No! So what if I'm a dream! I..I like being here.

Fayth: We've been dreaming so long...we're tired.

Fayth appeared on the other side.

Fayth: Would you and your father... Would you let us rest?
However, as seen in the above passage, the residents of the orignial Zanarkand who became Fayth for the Summoning were at least initially complicit in the idea.

Zanarkand was doomed
to oblivion. That's why we tried to save it-if only in a memory.
To associate Yu Yevon with Bevelle demonstrates a misunderstanding of the FFX continuity. Yu Yevon was an enemy of Bevelle; he was the leader of Zanarkand, which Bevelle fought. The Yevonite religion is effectively a corrupt power structure, similar to the Glabados Church of Final Fantasy Tactics. With Yevon, the original premise is derivative of an idea revolving around Yu Yevon, but never actually involved the Summoner. This is explained by Maechen.

Maechen:
"Rumors flew in Bevelle about Sin's sudden appearance."
"They said that the people of Zanarkand became the fayth, that they had called Sin."
"And that the man responsible..."
"was none other than the summoner Yevon, ruler of Zanarkand!"
"Yes, the lord father of Lady Yunalesca."
"On the eve of Zanarkand's destruction, Lady Yunalesca..."
"had fled to safety with her husband, Zaon."
"Later, the two used the Final Summoning to defeat Sin."
"Yet the people of Bevelle still feared Yu Yevon."
"It was to quell his wrath that they revered him, and first spread his teachings."
"And so were born the temples of Yevon."
"I suppose it's possible Yunalesca had planned it that way from the start!"
"A fair trade, she defeats Sin in exchange for her lord father's honor."
"Of course, there's no proof. No, the facts are lost in the mists of time."
"And who'd admit Yevon was an enemy of Bevelle?"
"You can bet the temples had a hand in covering that one up!"
"And that, as they say, is that."
Dream Zanarkand itself does not have a given religion, at least so far as we are told. It is merely a continuation of the original Zanarkand. Even Yevon, after all, is a false religion. Yu Yevon most certainly never conspired with Bevelle; he is incapable of human communication. Yu Yevon embodies Sin, and embodies the Summoning. There was no betrayal; Yu Yevon merely Summons perpetually, again as directly and unambiguously stated by the Bahamut Fayth.

Death does not give strength to Sin. The entity retains strength regardless of any encounters with people; it does not grow more powerful after an attack. Moreover, realize that one does not have to "die" to become a Final Aeon; one allows Yunalesca to turn them into a Fayth, which is not exactly the same thing. Also realize that such a comparison is nonsensical to begin with since Sin is not an Aeon, and does not need a Fayth for realization.

Fan fiction often deviates from the established canon and mythology of its source, whether a video game, book, movie, or whatever. If you wish to write according to the parameters you've created, then so be it. However, because a notion appeals to you does not mean that it fits the established mythology of the game--in this case, it clearly doesn't.

Please refer to my earlier explanation of a Calm. It has nothing to do with control; Sin does not cause death during such a period because Sin is being "rebuilt," so to speak. Following a successful Final Summoning, Sin is pierced. However, Yu Yevon simply possesses the new Final Aeon, and over a period of several years again gathers the pyreflies about that Aeon to form a new Sin.

Fayth: Yes. Even if you defeat Sin with the Final Summoning, Yu Yevon
will live. Yu Yevon will join with the Final Aeon. He will transform it
into a new Sin.

Yuna: Yu Yevon merges with the aeon...

Fayth: Then, protected by this new Sin he has created, Yu Yevon
continues the summoning.
If Sin reformed instantaneously, there would be no true period of Calm.
