Laugh Tale, originally known as "Raftel". is believed to be the final island on the Grand Line, where the One Piece, the world's greatest treasure, is located. This treasure, left behind by Joy Boy, was later discovered by the Pirate King, Gol D. Roger, who also named the island.
Laugh Tale's name was first revealed during a flashback involving Gol D. Roger and his crew, the Roger Pirates. As the only pirate crew known to have reached the island, they discovered the true history of the world, which includes the events of the Void Century, the secrets of the Ancient Weapons, and the true meaning behind the mysterious "Will of D".
Reaching Laugh Tale is not an easy feat. The island is hidden, and its location is unknown to most of the world. To find Laugh Tale, one must first obtain and decipher the four Road Poneglyphs, ancient stones inscribed with a unique language.
These Poneglyphs are scattered across the world and guarded by powerful entities, making the quest to find them a perilous journey. Once all four Road Poneglyphs are deciphered, they provide the coordinates to Laugh Tale.
