As you can see on the left side of screen there are some party going on behind the dunes :p
That pillars of light dance same as those in any Castrum.....but there is not any Castrum on that desert from what i know, what you guys think??
I remeber some cut scene about flying there and i remember that this was on some desert, maybe this is it :D

Yes, its Gold Saucer. I saw that as well :P

Yes many people know about it already. Many threads popped about this.

Yup, go further right and look through the mountain to see the cactuars eyes.
