Inherited will for what? The WG will already be already defeated and the Will lf D. fullfilled.
To be more generic than that only if Oda make couples and form a crew from with the kids of the SH
Why was Big Mom hiding one red poneglyph (who Roger took a print) if she didnt know what was it for?
Did u read my full post?
Roger confirm that the Roger Pirates were the first ones to discover Loadstar and the REAL use of the Poneglyphs
Inuarashi confirm that u only discover about the REAL use of the Poneglyphs when u get to Loadstar
Sengoku confirms that Rocks was after the taboos of the world because he wanted to become King of the World and that he attacked the WG, he clearly knew about the WG secrets and thats why he was errased.
I believe BM Poneglyph was originally from Rocks, and he was trying to uncover the mysteries of the WG and to take Imu throne, thats why the hunted the poneglyphs, but its clear that Roger was the one to first realize the use of the Road Poneglyphs, BM most likely discovered that they were related to the way to get to the last Island when Roger arrived there after stoled a copy from her one. And she was storing the stone because even if she dont know fully whats the use of It, she knew its something important, not only from Rocks time info, but also from the way the WG reac to It.
The biggest prof that she dont know fully the use of Road Poneglyphs is that WB also didnt know, and from what Roger say, no one knew about Laftel, everyone thinked the end of the GL was in LoadStar, Laftel become common knowladge after Roger.
U cant be reading the same manga as us. Oden literaly confirmed that they learned about the Void Century, Will of D., Ancient Weapons, etc on whatever JoyBoy have lefted in Laftel.
