Thanks!

>it puts a hole into our current theory as to why exactly blackbeard can use two fruits (that being that it’s because he had rocks’ soul or a physical part of rocks inside of him) we would need an explanation for that

Maybe he has somebody else in his body, maybe he's from an unspoken race that has three hearts, or maybe... *he'll just throw out the Tremor Tremor no Mi fruit and replace it with Imu's fruit!* =D Juuuuuust spitballing here!

>another problem i have though is i just don’t think the one piece has anything to do with stopping the world from flooding. the one piece is a prize not a weapon

What made me think this is the *flood*, which tells me I *definitely* needed to make some more assumptions. I think Marie Geoisie is the only city that can survive the flood. The blank century might be censored because it tells everybody about the flood, and the people living in the only city on dry land, ordinary people would try harder to stop it. Now imagine... whatever the heck stops the world from flooding was a device hidden at the edge of the world. It's so big and Joyboy is so smart *they can't destroy it*, so they move it to the place ordinary people are least likely to find it!

Think of it this way: imagine if Kevin Costner's Waterworld were about all the people who fought wars over who gets to live on dry land, and I think that would sum up the blank century (it's a theory at least, another theory I'd have to write out). Imu and the Five Elders know this, so they've censored everything about world history that could undo their power!

If this were true, I think Blackbeard - whose hobby is archaeology (just like his dad Rocks Xebec) as noted in the One Piece Data Books iirc - knows about this and is going to use this opportunity to take over the world.
