You mean the Vegapunk one? What is said about JoyBoy and Final Island?
Iirc it's stated during the broadcast that Joyboy left the answers/the key to saving the world at the final island which is why getting there is such a big deal for every faction now. Remember Koby saying he'll have to interfere with Luffy's dream? That's because SWORD/the Marines will likely try to reach the Final Island first
Do we know there is a treasure there that was left by JoyBoy? You know One Piece is a made up term by newspaper/public in general. Roger just took it in his own advantage to create the Great Pirate Era and pass his will forward (to Ace).
No I know. The One Piece is now Joyboy's treasure and Roger's treasure put together (most likely)
When Roger got there he found
something that Joyboy left there but claimed he was too early. He also stated that he left his own treasure there as well (theorized to be whatever the egg on his ship was) and those 2 things together form the
One Piece
Is not like there wasn't any explorers before Roger for 800 years... Right?
That's why I said the harsh conditions probably also played a role in it. A lot of explorers die before even reaching the Grand Line or they have a hard time making it through the New World
I'd imagine the path to Lodestar is fairly perilous
How about sinking the island? Only know they have Mother Flame but couldn't they pursue the DF or the user of the Quake no Mi?
I mean they can't just magically find every fruit. The only fruit we know with those capabilities is the quake and it's 1 fruit that could potentially be on any one of the limitless islands in the world
Not to mention that there's really no reason to destroy Lodestar anyway. It's completely useless if someone cant gather all 4 Road Poneglyphs
and read them which is almost impossible. Roger was only able to do it because he got absurdly lucky and ran into Oden
If Luffy didn't stumble upon Robin in Alabasta his journey would be over before it even began
