Big Momhas one of them.
- Another one is held by
- The third one is on the moving island
- The location of the last is
So we could say Big Mom and Kaido have
1/4 information about the location of raftel. And we assume the don't share this information among each other. So they are pretty far from finding this island.
Ruffys crew is the only known to know 2 road porneglpyh (made a copy of Big Mom's and the one on Zou), so he has
2/4 of the information.
So Ruffys crew is at moment in the best position to find raftel. But: even if an other crew had all the road porneglpyh, they can't read them. How are they supposed to get the information that is written on these stones? Is
Nico Robin the only way to get the location of raftel?
