Alright; this is purely speculation; and I myself can see several things wrong with this theory, but I decided to type it out anyway simply out of boredom and the urge to well, speculate.
First off, the three Ancient Weapons; Poseidon; Pluton; and Your-Anus Uranus.We already know that each of these weapons is capable of mass destruction; it's also been shown that the Ancient Weapons have been around either prior or were possibly created/conceived within the Void Century. They've been shown to be closely interlinked with the Void Century; with hints to their location being documented on the Poneglyphs; indestructible rocks left behind by the Ancient Kingdom which contain various snippets of information; mostly those involving the ever so mysterious Void Century. This lead us to believe that the Weapons may have been either created or owned by the Ancient Kingdom.
We already know the location of Poseidon and what it; or better yet she is. It's a mermaid;a mermaid with the power to both communicate and control the dreaded Sea Kings. This ability has apparently been passed down through the Royal fishman family; although has only been present in few; presumably only two mermaids. It's original owner; Poseidon; who upon death had her name treated as a title that was given to those who possessed her power, and her great descendant Shirahoshi. What's strange about this ancient weapon is that it's not a inanimate object, rather it's a living being. Perhaps this could be related to the fact that Uranus and Pluton are named after planets whose name coincides with a Roman or Greek god; while Poseidon is just named after a god not a planet. Making Poseidon the od one out and thus living being.
Then there's Pluton; strangely it isn't named Pluto; but rather has an extra character giving it the name Pluton. Of course it is a sort of natural response to remove the N and immediately intertwine it with Pluto; a planet associated with the Roman god that rules the underworld. Also; since Poseidon is of course a name that quickly brings up thoughts of the sea; while Uranus is linked with the sky; it wouldn't be far fetched to assume that Pluton may be something to do with the earth. Although it has already been stated that Pluton is a ship. A ship that sails the sea? Boring. A ship that can traverse through earth? A little more interesting; makes more sense as well if you take ino account it's namesake. But; is that N really unintentional? Could the N signify that Pluton is a ship that not only sails though earth, but can also create earth? Pluton: A pluton in geology is a body of intrusive igneous rock (called a plutonic rock) that is crystallized from magma slowly cooling below the surface of the Earth. - Taken from good 'ol Wikipedia. A ship that sails through earth; has the ability to create rock by spewing magma, or perhaps by some other means, though the magma does fit, after all Underworld- Hell -Fire - Magma etc etc, yada yada. Sounds cool?
Then there's Uranus; probably some kind of Sky Weapon. Meh.
Next there's the Ancient Kingdom, a Kingdom that went to war with the united 20 Kingdoms and lost. It lost. A kingdom that is implied to be rather spectacular; so much so that they foresaw their loss and created stones on which they inscribed their secrets. Stones that are indestructible; stones that no matter how much the WG tries, they simply can't do anything about. This Kingdom seems to also be heavily intertwined with the Ancient Weapons, possibly being their creators. This further highlights how great this civilization; which even when destroyed continues to haunt the WG, may have been. But, this Kingdom was destroyed seemingly within a century, a century now dubbed the Void Century. Now, what's the best way to destroy a gigantic kingdom which seemingly ruled the majority of the world? Perhaps divide and conquer?
I don't know if it's just me, but the Redline has always seemed so unnatural. It's freakin' huge; seemingly the same height all around; traverses a straight line, and despite being around for hundreds of years only has one hole; fishman Island. Perhaps the Twenty Kingdoms created the Red Line using Pluton? Sail the world once with that ancient ship and while doing so create a 10,000 meter high rock wall along with a giant mountain. Definitely seems far fetched. Although it's been said that Poseidon alone could sink all of the lands of the word, so maybe not so much? So let's say that by some miracle the 20 Kingdoms managed to sail around the world creating the red line without being interrupted by the Ancient Kingdom? What then? Well of course Mariejois's creation should perhaps be priority, as they would need the ability to freely cross between the four blue while preventing the now segmented Ancient Kingdom from doing so. At which point they're free to pick off the divided kingdom bit by bit. Of course I have no guesses as to what the Grand Line is; perhaps it's always been there; and it was the goal of the ancient Kingdom to get rid of it and unify the world. In which case allowing for the creation of the Red Line would be rather retarded? Or maybe it was created thanks to the discord caused by the creation of the Red Line itself. Or possibly using another Ancient Weapon? Although perhaps this can explain the weird structures on Reverse Mountain; maybe the Ancient Kingdom built the waterways in an attempt to unify the seas again and begin their counter-attack against the twenty kingdoms. Also, perhaps the hole which rests around fishman Island was the Ancient Kingdoms original attempt at destroying the Red Line. With Noah being a ship for evacuation, with Joy Boys' promise stemming from the fact that Fishman Island would have to be evacuated so that the Ancients could blow a hole big enough in the Red Line to allow for free travel and the destruction of Mariejois.
Then there's East Blue; perhaps this is the Twenty Kingdoms original domain; which would explain why it's the weakest in terms of piracy. Perhaps piracy was originally resistance and rebellion against the twenty Kingdoms impending rule; probably carried out by the Ancient Kingdoms remains and its descendants. With East Blue being Pro Twenty Kingdoms there would have been little rebellion. However the series' greatest pirates and leading revolutionary as well as the series protagonist itself all hail from East Blue. Perhaps some of the more prominent Ancients sought asylum right under the enemies nose rather than fleeing to the far reaches of the earth (Insert speculation as to why here). Perhaps the bridge that's being built in Tequilla Wolf could be some sort of long time goal of the Twenty Kingdoms stemming from their original habitation of East Blue.
Then there's the fact that if the Ancient Kingdom did launch some sort of all out last attack on Mariejois directly, possibly by sailing through paradise; had the attack failed they'd have two options of escape. Either by fleeing deeper into the Grand Line, into the New world and towards the opposite side of revers mountain; or back towards the entrance of the Grand Line. Perhaps they scattered the Poneglyphs as they did so. With the prior group either reaching or creating Raftel. Perhaps they stole back the Ancient Weapons that weren't currently in their possession while doing so. Which would allow for the creation of a nearly impenetrable barricade to protect Raftel which held the Ancient Kingdoms last hope at revenge and returning the world to how it should be. Perhaps the Devil fruits source, the Devil Tree? Lol, was created through use of the Ancient Weapons; all three of them combining to create a fourth and final Weapon. Water (Poseidon), Air (Uranus), Earth (Pluton), requirements for a plants life? With the plants fruit being scattered throughout the world via Reverse mountains currents. <- (Taken from another theory I read a while back on NB; posted by Lili-Chwan I think?). The Devil Fruits of course serving as a means to give individuals power; power to strike back at the newly formed WG's cruelty.
Lastly the fulfillment of someone elses will has been personified throughout One Piece. For instance Luffy ringing the bell at Skpia in the other guys stead along with many other examples. It's only a matter of time until the ultimate will held by a gigantic Kingdom is fulfilled. Which would lead to the Red Line's destruction; the creation of all blue and the destruction of Fishman Island thus fulfilling the prophecy given to Luffy at fishman Island. Along with the ability to fulfill Franky and Nami's dreams.
T_T Fudge this is long.
