Ok, If you say that evry single word that you said you write it down exactly from a Square official publication I would Shut my mouth, And get my airplane to find Znarkand in another place. But if you get those words from that guide , who have mixed text from Forum topics and official infomation , I Can still fighting my argument, because they know the same I know about this Story, And they are really saying what they think just like me. If you read the guide, you may noticed that the only thing that they got from Ultimania Omega Guide about sin was ".the additional explanation that Sin is formed by
gravity spells concentrating pyreflies around the core". So . I guees nowhere in that guide says "DZ is not inside Sin".
