Ok I know that yu yevon summoned Dream Zanarkand and all its inhabitants like Tidus and Jecht and that Sin is an armor of Yu Yevon made by him fusing with an Aeon and also to destroy machina and prevent civilisation growth. But why exactly did it attack Dream Zanarkand? And also how does Jecht end up in Spira? I've heard that DZ exists in a physical location near Baaj temple so does that mean anyone from there can get to the rest of Spira and vice versa? If so how come nobody has ever found it surely the aiship should see it at least? Sorry for all of the questions but rather than make loadsa threads and since the game doesn't make everything clear and I've searched a lot for these things that I already know as it is. Thanks in advance for any answers, theorys or to point out any mistakes I may have done (New)
