The World of One Piece
One Piece takes place in a fictional world. The One Piece world is definitely not our Earth. This gives the author lots of freedom to create his own world. And the world he created is fantastic!

The One Piece world is definitely a product of very constructive thought. It is complex and easy at the same time. We´ll make sure that everyone understands how this world functions. If your are looking for any specific places then you´re wrong here. In here you´ll just find discriptions of the environmental properties of the OP world. To read something about specific villages, islands etc. go to the Scenes of Action page.

The first thing that needs to be mentioned is the time where the story takes place. Since One Piece is a pirate adventure, the age in the story resembles the colonial times of the real world. Of course there´s lots of differences to the real world here and there, but the ages can roughly be compared to each other.

In the world of One Piece, there seem to be three big different kinds of environments in which everyone lives in. The first is the Blue Sea, which is the massive ocean that covers most of the world of One Piece. The next one is the Sky Ocean which as the name indicates is an environment in the sky. The third one hasn´t been given a official name so far since it only appeared in a side story, but since the surface and sky environment have been mentioned, the last one is the Ocean Floor world.

The Blue Sea
The Blue Sea, which is where the bulk of the storyline takes place, consists of one large continent, one long chain of islands, and Four Seas that make up two larger oceans. The continent is called Red Line, the big chain of islands is called the Grand Line and the Four Seas are called North Blue, South Blue, East Blue and West Blue. The map below should be helpful to visualize that.

The Red Line
The Red Line is the one and only continent in the One Piece world. It circles the entire world from north to south. The Red Line seperates the two oceans into four smaller seas. One ocean makes the two seas East Blue and South Blue, the other one makes North Blue and West Blue.

The four Blues
As explained above North Blue, South Blue, East Blue and West Blue make are the four seas of the world. Or the four Blues in other words. Within each Blue, sea travel works as it does in the real world. You can sail to any destination you want with a regular compass. However getting from one Blue to one other is much more difficult. The reason why it is so difficult is not only because the Red Line seperates the two oceans, but also because the seas within one ocean are seperated by a large sea route called the Grand Line as well as two Calm Belts.

The Calm Belt
A Calm Belt is a sea area that surrounds on each side of the Grand Line as the picture below shows.

These regions are constantly calm. Winds do not blow and sea currents do not flow within this region of the sea, hence the name Calm Belt. As a result, sailing through it is difficult. But the main reason why ships shouldn´t sail through the Calm Belt is because it is the nesting ground for Sea Kings. And only for the large kind. Even if a ship doesn´t require wind or currents to sail, it would still be in danger of being attacked by these creatures that can be the size of islands. These two reasons are why the chances of entering the Grand Line this way are very slim.

The Grand Line
The Grand Line and the Red Line have one thing in common. Both go around the entire world. But unlike the Red Line, the Grand Line goes from east to west. The Grand Line isn´t a continent, but one big line of islands that come one after another. Since the Grand Line is surrounded by the Calm Belt on both sides, it isn´t easy to enter this route. There is only one way how ships from each of the four Blues can enter the Grand Line and that is Reverse Mountain. The pic below shows a map of it.

As the map shows, Reverse Mountain is one of the two points where Red Line and Grand Line meet each other. The Grand Line begins right there. Reverse Mountain reaches into each of the four Blues. Each Blue has an entrance at the foot of the mountain. The entrance is a river that flows up the mountain thanks to the immensely strong flowing current. Since the currents are so strong that they can make rivers flow up instead of down the mountain, maneuvering under these conditions is very hard. And if a ship misses the entrance then it heads directly into the mountain and crushes there. That´s why entering the Grand Line is a tough matter. However if a ship successfully entered the river then it practically entered the Grand Line already. The rivers from all four Blue´s flow to the top of the mountain and from there on there´s only one river that flows down again and that one takes the ships directly to the beginning of the Grand Line.

Once a ship entered the Grand Line it entered a route with it´s own strong magnetic field. The islands of the Grand Line each are so rich with minerals that they cause abnormal magnetic fields along the entire line, which makes the usage of a regular compasses impossible. To navigate safely through the Grand Line, the crew needs a Log Pose. A Log Pose is a special kind of compass that adapts the magnetic field of the next island. Below is an image that shows how the navigation this way looks like.

After the Log Pose adapted the magnetic field of the next island it will constanly point in it´s direction showing the crew the correct direction towards an island. After the crew has landed at the island the Log Pose takes some time to readapt the magnetic field of the next island and then everything starts all over again. Traveling through the Grand Line is goes step by step. However there´s different routes that can be taken to travel that way and this can only be done at the beginning of the Grand Line at the Cape of Twins.

From here on there´s seven routes that can be taken. Each one begins with an island and once a route is entered there´s no turning back and it has to be followed until the end. The image below shows how that works.

Each of the seven routes follows the same step by step traveling rule. As it can be seen on the image further down the routes the Grand Line meets the Red Line for a second time, but as seen on the image the journey doesn´t end there. How exactly the routes cross the Red Line isn´t clear yet because the story didn´t get to that point yet. The routes themselves will sooner or later meet and join with each other until they all become one final route that ends at the last island of the Grand Line, Raftel. What waits there and how the Grand Line can be left from there on is yet to be revealed.

As explained, following the step by step rule with a Log Pose is an easy way to navigate the Grand Line. What makes travels on the Grand Line is the climatic conditions there. The many islands with their magnetic fields cause huge disturbances in the weather. On the direct route from one island to the other the weather can change from sunny to strom to snow to sunny again all pretty rapidly. Predicting the clima is impossible there and Hurricane´s can come up in a second and destroy entire fleets. This climatic disturbances are what makes the travels within the Grand Line dangerous. The only places where the weather is stabilized is within the magnetic field of the islands themselves.

There´s also appears to be ways how the Grand Line can be left lafely without sailing to the far end of the Grand Line. But how that works hasn´t been explained so far.

The Sky Ocean
The Sky Ocean is a place that is unknown to most people in the Blue Sea. The reason for that is that the Sky Ocean is entirely made of clouds, which from the Blue Sea doesn´t look like an ocean in which people live after all. The Sky Ocean clouds however are no normal clouds. There´s two kind of clouds up there, Sea Clouds and Island Clouds. Sea Clouds are just as water, which means that you can sail on it if you´re not to have to sink through it, whereas Island Clouds are dense enough to carry all kinds of things.

The reason why such clouds can exist explain itself through an extraordinary solidification process. The responsible element for this is Seastone which comes from the Blue Sea. It can be found in "Pyrobloin" which is a sulfur protein particle that gets transported into the sky through volcano eruptions. When it reacts with the vapor, the differences in density determine whether Sea or Island Cloud will be formed. The image blow should help to visualize it.

There´s different ways to get to the Sky Ocean from the Blue Sea. The only way that has been shown so far is the unorthodox and dangerous way in which the sailors have to to take a Knock Up Stream (soon to be explained more deeply). How the other ways work hasn´t been explained yet. In the Sky Ocean there´s two known sea´s, the White Sea and the White White Sea.

The White Sea
This sea lies 7000 meters above the surface. It is the lower one of the two seas and lies between the Blue Sea and the White White Sea. To get to the White White sea from here one has to take the Milky Road road which is a manufactured river of sea clouds. The only known place where a Milky Road that leads to the upper sea can be found is Heaven´s Gate.

The White White Sea
The higher of the two known seas in the sky. It lies 10.000 meters above the surface of the Blue Sea. To get to the White Sea from here the same Milky Road as mentioned above can be taken. Whether or not there´s other Milky Roads that connect the White White Sea to the White Sea is not known so far.

To leave the Sky Ocean one has to go to Clouds end and take an Octopus Balloon there. The Octopus Ballon which grabs the ship that wants to get to the Blue Sea, blows itself up with hot air and slowly glides down.

The Ocean Floor
Not much has been shown about this world so far. Even the name Sub Ocean was just made up by ourselves to have a reference name. It is at no point the real name for this place. The Sub Ocean so far has only appeared in Hatchans manga side adventure. Almost the entire adventure took place below the sea where some creatures and places got introduced. Hopefully at there will be more shown about that world at some point of the manga but so far there´s only that little event.
