User blog:Balbal1/End of the Grand line

Uraharattack said before in a blog post that since that you need 4 Road  Poneglyphs  to reach  Raftel and you can't just follow the Log Pose to reach it then what is on the end of the Log Pose route?

and that lead us to a lot of questions like...have anyone reached it?, and does it holds the 4th Road Poneglyph?, and does anyone currently live on it?, and does it has a connection with Raftel?, we will just have to wait to know the answer, but we can at least say it will be very important island just like Raftel, and i assume that it will be a depopulated island and Luffy will find the 4th Road  Poneglyph in it or it will be a normal island where Luffy will fight someone and help the  citizens just like any island he visits
