"Like there are people who will inherent Roger's will. . .Some people inherit Ace's sometime in the future! Even if you break their blood bond, you'll never be able to extinguish their flame! That's how it came down unbroken throughout their ages! And someday in the future, carrying hundreds of years of history on his shoulder, someone will fling down the gauntlet in front of the world! Sengoku! You and the World Government are afraid of the gigantic war that would embroil the whole world in one day! I've no interest in it but when someone finds the treasure, the world will turn upside down!....The One Piece is real!" - Whitebeard

"In some places, there are people who call the Family of 'D' "Sworn enemy of the gods"!" - Rosinante
"His dream, or fate?" - Woop Slap
"The Family of 'D' have been hiding in the shadows of history. When and where are they gonna show themselves? Who's gonna side with who? Who's gonna betray who? Tell the Celestial Dragons in the Holyland of Mariejois that they'll be dragged down! It's been 25 years since Gold Roger fully explored the whole Grand Line. His arch enemy, Whitebeard, didn't sit on the throne, but just stood in front of it and took the reins. What about now? The number of pirates is ballooning, and there's one that's totally empty. You know what I mean, don't you? It will start. The biggest struggle for supremacy ever in the history of pirates!" - Doflamingo
"...the ones we want to know the most are the engraved messages of the Poneglyphs and the reason of their existence. Why did people of the past carve their messages on hard stone in an attempt to transmit it to the future? They engraved history on unbreakable stones and dispersed them throughout the world. Wasn't it because they feared having their messages destroyed, if they were to lay it on paper or in books? In brief, this is evidence that the people who left this behind had a clear enemy. . .If we consider the other possibility of these people being defeated by some enemy, then that enemy should have survived and stayed in the history. Oddly enough, eight hundred years ago, just as the Void Century finally came to a close, the organization known as the World Government was created. If the enemy of the fallen people was today's World Government, then we can come to a conclusion that the Void Century is inconvenient history that was erased by the hands of the World Government. By reading historical documents from that time and by deciphering a certain number of Poneglyphs, we noticed the existence of a country before too long. What these texts revealed to us was the shape of a powerful country. It once took pride in its enormous strength, but all information on that country has been completely erased. It's very probable that when they realized the deeds of an allied nation, referred to as the World Government, they carved the truth on stones, in order to entrust their ideas to the future. These are the Poneglyphs that remained in this world to this day.
The ancient weapons will indeed coerce the world. But more importantly, won't the existence and ideas of that country, being revealed along with the true history, be even more of a menace to you, the World Government? We must make clear the nature of this menace, but what holds the key to solving everything is the name of the once flourishing country..." - Professor Clover
