Look at the 7th sea and the 7th continent!!!
In the South Pole, Antarctica is a place where a sea and a continent merged to become a piece, ONE PIECE.
I think “One Piece” is also located where the 7th sea and the 7th continent merged to a piece.
So far, we only know 6 seas in One Piece world: East Blue, West Blue, North Blue, South Blue, Paradise, and New World. So where is the 7th sea?
Other questions, what is a continent? And do we have continents in One Piece world?
In One Piece world there are only islands. Even Red Line is just a group of Islands connected together.
First, let us look at the definition of a continent!
By convention, continents are understood to be large, continuous, discrete masses of land. Moon is also a huge, continuous discrete masses of land.
Therefore in One Piece, the continents are the moons.
However, there were only six moons in the model of Earth in Ohara.
