It's just that the story sounds like it might be like what happened to the place I came from. A thousand years of death, all kicked off because a summoner couldn't let go of his grief. Don't want to jump to any hasty conclusions, but...

Long story cut very short, there was once a summoner called Yu Yevon. He lost a war, saw his city destroyed, and compelled all his surviving summoners to become summoning statues dedicated to summoning a dream version of his lost city. I'm from there, actually. But that's an even longer story.

Anyway, to protect his new dream city, he conjured this horrible floating monster called Sin and programmed it to destroy any settlement that got too big. He didn't want people getting hi-tech enough to find his dream city.
