Florian Triangle

The Florian Triangle is the stretch of sea that one has to cross over to reach to the Fishman Island. It acts as a Bermuda Triangle of One Piece World. It is covered in a fog so thick that it blocks out all sunlight. According to Kokoro, many pirate and commercial ships mysteriously go missing every year and some times a ship will be found sailing without any people aboard. Due to this mystery it is also been said that there are many haunted ships with dead bodies sailing across the sea.

During the Thriller Bark arc, Straw Hats went to this accursed sea on their way to Gyojin Island and discovered that Gecko Moria was using the Florian Triangle to trap victims to be used for his zombie army. Though Moria's scheme can be attributed to some of the many disappearances that happened in the Florian Triangle, the mystery of ships disappearing in the sea has long since been happening even before the great pirate ship, Thriller Bark, first cast its shadows upon these water ten years ago before the current time line. This mystery is confirmed by an unknown ominous entity larger than Thriller Bark that was barely seen by Captain Lola through the fog. It is so large that it completely dwarfs Thriller Bark in sheer size.
