4. The real importance of the Ancient Weapons
As it turns out, if I had a nickel for every landmass in the One Piece world that’s made of several islands with separates climates stuck together, I’d have two nickels. That’s right, it’s the Red Line.
The Red Line is unambiguously stated to be composed of smaller islands assembled together. That’s despite looking nothing like a collection of islands in terms of shape : it’s all cliffs, and (from what it seems so far) perfectly flat at the top.
Add the fact that it circles around the entire world in a straight line. It really is a very unnaturally shaped continent. I see only one explanation for this !
I believe the Red Line is a Pluton construction as well. It might have been made during the Void Century, or earlier. This would mean that there once was much more land in the world, maybe even large continents, that got all used for the construction of the Red Line. As for who would have done this and why, I could not say.
What I would say, however, is this : I believe the other two Ancient Weapons were also involved in similar world-shaping work.
The One Piece world, however crazy it is, features three great “anomalies” that really shouldn’t naturally exist : the Red Line, the Grand Line and the Calm Belt.
The Ancient Weapons are known to be “powerful enough to destroy the world”. If there’s anything in the world that could have created the three anomalies, it’s them.
Each of the three Ancient Weapons bears the name of a god that is associated with a certain domain of the world, which can in turn be associated with one of the three anomalies :
- Pluton, God of the Underworld – the underground – power to shape the earth – the Red Line, a continent that shouldn’t exist
- Poseidon, God of the Sea – the sea – power to command Sea Kings – the Calm Belt, a stretch of the sea with an extremely dense population of Sea Kings
- Uranus, “God” of the Sky – the sky – ??? – the Grand Line
I’ve just explained how Pluton the construction ship could be responsible for the creation of the Red Line. For the Calm Belt, I think you’ll agree that the most important thing about it is the Sea Kings population that makes it impossible to navigate. Well, if that didn’t exist, Poseidon would be literally the perfect tool one would need to create it.
Or to say it differently, if you wanted to cut off a strip of sea from the world, and you had Poseidon at your disposal, the result would be the Calm Belt.
Obviously the Uranus one has yet to be fulfilled and is therefore pure speculation going beyond the purpose of this post. Though I will say there are quite a few theories about Uranus having to do with the weather, and the weather is certainly a big part of what makes the Grand Line unique.
Anyway, that’s the end of this theory. I’ve had most of this down for some time, but the latest reveals suddenly made the theory a lot stronger by providing the connection between Pluton and Wano.
Again, I have no idea how Pluton actually works, this is only a theory about the purpose of it.
Thanks for reading !
EDIT : Adding a fantastic point brought to me by a fellow redditor regarding Fishman Island.
So everyone is familiar with the prophecy that Fishman Island will one day be destroyed by the hands of Luffy.
The most commonly accepted answer to this mystery is that the Red Line will be destroyed at some point using Pluton, and the island will be crushed by falling rubble, forcing the residents to flee using the Noah.
In the context of the present theory, this scenario does not work, since Pluton can let us remove the Red Line without leaving any rubble.
But ! What does work and is even better, is this : Pluton will be used to move Fishman Island from its current location to the surface.
The island will technically be destroyed temporarily, hence the prophecy. And the Noah will be used to transport the residents.
Since the Noah is moved by Poseidon, this will mean at least two of the three Ancient Weapons will be involved in the emigration of Fishmen and Merfolk to the surface. Wonder if it’ll actually be three ?
