So the Poneglyphs do guide one to Raftel!
And so the story shifts back to journey towards Raftel and the dangers awaiting the Straw Hat Pirates in their path. The Red Poneglyph aka. “Road Poneglyph” serves as a guide to reaching the final point of the Grand Line, Raftel. Carved in four Red Poneglpyhs are the locations of certain points which when joined reveal the location of Raftel at the point where all the lines intersect. With one of the stones found, Nico Robin now needs to read the remaining three in order to find the location of Raftel. Easier said than done though as two Yonko each have in their possession a Red Poneglyph.
