Location from One Piece by Eiichiro Oda
The second half of the Grand Line, beyond Fish-Man Island. Yonko territory where the sea itself seems alive with malice. Veterans of the first half call it the real Grand Line.
If Paradise is where dreams are tested, the New World is where they are broken or forged into legend. The four Emperors — the Yonko — divide this ocean between their territories, and any crew sailing these waters without an Emperor's flag or the strength to defy one is prey. The islands here reflect the madness of their rulers: Whole Cake Island is literally edible, Wano is sealed behind waterfalls that flow upward, Onigashima floats through the sky on a dragon's power. Navigation is exponentially harder; even experienced crews get lost between islands that change position. The New World respects only one thing: overwhelming power. Everything else is kindling.
Seas of fire, rains of lightning, islands that appear and vanish overnight. Currents that flow upward. Oceans that solidify without warning. The sky splits with anomalous weather that defies physics — and the strongest pirates in the world have carved this chaos into their personal kingdoms. Every horizon promises something that shouldn't exist.
