User blog comment:Falquian/One Piece, Roger and Poneglyphs. Theory./@comment-1595565-20101120065843

Rayleigh said that Robin might draw a different conclusion than he and the rest of the crew did. That makes me think that the Rio Poneglyph is telling a story of some kind. However, it only tells one side, the side of the Ancient Civilization. Therefore, there is bias. The Roger Pirates probably realized this, and could only come to a conclusion based on the information given. As for Crocus and Rayleigh living at the beginning and middle of the Grand Line, I thought about that too. I think the person waiting in the New World is Shanks, to be perfectly honest.
