Spiran History

[Little Blue]

Aye, they are in Japanese.

There are people who can better answer this than me (Auron's Ghost, Masamune-1600, and Renmiri), because they have the Ultimania, and are well versed in FFX symbolism and interpretation. Of course, this should be enough to get you started.

hehe, I don't actually have the Ultimania Guides, what I know is from reading translations and debates such as this, But what you said is pretty much it...

I don't think the Ultimania's go into detail about the cause of the War.

I personally disagree with the Ultimania timeline for Shuyin's capture... It implies that when he was captured he did not know that Lenne was in Bevelle and therefore the dialogue in the Journey's Start Sphere makes little sense.

Let me go. I want to see the Summoner. What would you do if she was your girl?

(not a direct quote mind you)
I think it makes much more sense if they both reached Vegnaguns chamber, were shot, and only Shuyin survived, imprisoned, and later executed... but that is going against the Ultimania timeline so meh...

As Tavrobel said, Jecht swam too far out to sea one day, and encountered Sin. Because Sin is made of Pyreflies held together by a Gravity Spell, and Jecht is made purely of pyreflies, Jecht likely got stuck on Sin for a short while, eventually being dropped in Spira. It was purely accidental.

I don't see why other DZ citizens couldn't also make it to Spira by the same method... The only reason why we wouldn't know about them is because they weren't as lucky as Jecht, ie, shot, executed, mauled by a fiend...

The use of the word Dream is slightly misleading. I believe that the Ultimania's state that DZ is real. It is summoned into reality from the dream of the Fayth, much like other Aeons are brought into being by a Summoner summoning the Fayth's dream. Therefore it is reasonable to assume that Sin could come ad go as it pleases without having to cross into another dimension (though this would be against Yu Yevons interests to allow Sin too close as it would treat DZ like it did the real Zanarkand 1000 years ago) . Hence DZ is located in the physical world somewhere, and the only reason why Spiran's don't know of it's existence is purely due to the fact it is too far away. Normal Spiran's have little interest in exploring the ocean, and the Al Bhed would probably have some old records in their ships computers telling them that there's nought but water and thus wouldn't bother exploring it either, but that's my own theory as to why DZ is undiscovered...

Finally, as Tavrobel said, Auron is dead. It is only his will to keep his promises to his friends that he has remained on Spira. Otherwise I think he would have accepted his death and gone to the farplane, or just become a fiend if he had some hatred towards someone or something. As Auron is an Unsent, he is purely made of pyreflies, and like Tidus and Jecht, could ride Sin in the same way... and the same would probably apply to any unsent, fiend or aeon.

If someone with the Ultimania's can correct any of that it would be appreciated...
