The Location of Dream Zanarkand

[cally777]

I think a nearer comparison than the Matrix is the Truman Show.
For a while you can fool people not to leave the "bubble" they are in, but not for ever, and not for 1000 years.

Yevon could have made the citizens of DZ any way he wanted, since he was their creator. Obviously, if they believed they were in the real Zanarkand, they would leave DZ to search for Bevelle, and be too difficult to control while maintaining Sin. His only goal was to keep DZ alive forever; this would be easiest if the citizens didn't wonder about the outside world.

I think (I haven't seen it in ages) that Truman needed a trigger to consider leaving the bubble. That trigger was a workroader he met never met saying "Goodbye Truman". However, Tidus knows that Auron is not a native of DZ, but since he's content to spend the rest of his life in Zanarkand, the trigger obviously has no effect on people in DZ. If the creators of The Truman Show (the show within the movie, not the movie) had been able to mould Truman the way YY moulds the citizens of DZ, he never would have questioned his universe.

You're right, he did need a trigger! So what could have triggered Jecht into leaving DZ? Not Auron obviously (though he could have triggered Tidus).

There is another kind of being able to appear in any part of Spira at least to those who can see them (Summoners and DZ people?) The Fayth. The Fayth wanted to end Yu Yevon's control over them. A Fayth talks to Tidus even before Auron does.

So maybe it was the Fayth that guided Jecht through whatever barriers Yu Yevon had set up around DZ (to answer my own question).

. At any rate DZ did exist in isolation for 1000 years, so to say it couldn't is a moot point.

Obviously, but the point is why? If we knew more about how and why Jecht left DZ it would help.
