What is the Grand Line in One Piece? The grand line isn’t exactly a complicated concept to understand, but it certainly is more than what meets the eye.
The Grand Line, simply explained, is the start of a rookie pirate’s adventure. Referred to as a Pirate’s Graveyard, it is a place wherein uncertainties and brutal battles of the fittest occur. There was this recurring statement during the beginning parts of One Piece when they would emphasize that “those who entered the Grand Line never came back alive.” This, of course, is true. Because when you enter the Grand Line, you either become a successful pirate, or you die defending your territory from someone who is stronger than you.
The Grand Line is basically a route in the One Piece world where pirates would roam around. It is said that those who have traveled in the Grand Line (and have completed all the routes inside) have traveled the world aside from the already known North, South, East, and West Blues, the Grand Line completes the world. The only known pirate (up to the present day) who has traveled to and from the Grand Line is the Pirate King, Gol D. Roger.
After officially acquiring the One Piece, Roger willingly turned himself in and was executed in Logue Town, the city that sits right before the Grand Line. Which meant that he was able to travel around the world and go back to his place of origin. His hometown.
During the first few episodes, it was established that the Grand Line is supposed to end at one point, and the Log Pose, a device used by pirates to lock in their destination (compass, but it locks to one island at a time), is supposed to lead them there.
However, the Grand Line is split in the middle by the Red Line, the first section (pre-timeskip) is known as Paradise, and the second (post-timeskip to current) is known as the New World. The New World and Paradise both have completely different auras. This is seen in the series as well. Only those who can conquer even the mightiest of opponents are fit to pass through the Red Line and into the New World, where mighty foes like the Four Emperors await. Those who are not so lucky end their journey in Paradise.
