New World

The New World... A place where people who will begin the next generation gather!! He who conquers this sea will become the "Pirate King"!!! The New World (新世界, Shin Sekai) refers to the second half of the Grand Line. The only people to have fully explored it are Gol D. Roger and his crew. It holds the location of the final island on the Grand Line, Raftel, where it is rumored that the legendary treasure, One Piece, and the true history, Rio Poneglyph, are placed. It is also where the Yonkou, four (now three) of the strongest pirates in the world, reside. The New World goes from Mariejois to the other side of Reverse Mountain.

Other islands of interest within the New World are Wano Country, where the legendary swordsman, Ryuuma, originated from. Also, somewhere in the New World is an island with a special shop where Vivre Cards are manufactured.

According to Gecko Moria, one will lose everything one cherishes in the New World, something he personally experienced. He also claimed that one shall face what he calls "The Ultimate Nightmare" there, indicating it is a very dangerous place for even the most talented pirates like himself. The New world is such a terrible challenge that some pirates refer to the first half of the Grand Line as "paradise" when compared to the second half.

Trivia

 * Its name is a reference to the Western Hemisphere (including North America, South America, and the Caribbean), which was nicknamed the "New World" during the European exploration. This was in comparison to the "Old World" or the Eastern Hemisphere in the perspective of a Eurocentric world view.
