What if Chiyo had simply told Sasori the truth about his parents?

What if Danzo hadn't interfered with the attempt at reconciliation between Hanzo and the Akatsuki?

What if Kaguya had in fact succeeded in her plan to put everyone under her control? Is the continent of the "ninja world" all there is? Would she have moved onto other parts unknown?

Stemming from that. Is the map of the ninja world the world spread on a flat surface or are we seeing only the "known world" and there's a whole continent on the other side? Where DID the Daimyos? I kind of thought they always lived north where the map seems to cut off... We really don't know much about them, only that Kishi wanted to add a few parallels to the AU pre-Meiji era Japan that Naruto is based on.
