[must've been Atem or someone, then. Right, story time.]

Nearly twenty-five years ago, the Pirate King was finally captured by the Marines and set to be executed. Some say he let himself be caught, to let his crew escape. On the execution platform, he made a declaration: that he left his treasure, that he called the One Piece, at the end of the Grand Line, on the final island Raftel. He said, 'if you want it, go get it,' and then they killed him.

Any pirate who says they're not searching for it is either a liar or a coward, afraid to risk their life.
