Grand Line

The Grand Line is a dangerous, unpredictable ocean route in the fictional world of "One Piece." It runs across the globe, segmented into two halves separated by the Red Line, a huge landmass. Navigating the Grand Line requires special skills due to sudden weather changes, powerful sea creatures, and tricky currents. It’s known as the most adventurous part of the world's seas because it holds many islands with unique cultures and treasures. For sailors and pirates, crossing the Grand Line is a major challenge and a key step in their quest for fortune and discovery.
