Robin found out that there are tablets of truth and tablets of clues. The tablets of clues lead to these tablets of truth. Also the Rio Poneglyph seems to be the record of true history. However, True History seems to be spread throughout the tablets of truth. But is the Rio Poneglyph the combination of all the Poneglyphs of truth? Or do the tablets of truth tell parts of where the Rio Poneglyph is. Also, what happens if the tablets of clues tell them to go somewhere like the Red Line? That would make One Piece go global. Nami would like that so she could map out the world, and everybody else will live new adventures.
Point is can somebody that really knows about Poneglyphs explain them? I am really confused.
