Rainbow Mist



The Rainbow Mist (虹色の霧, Niji-iro no Kiri) is a mysterious fog that is in fact a gateway to another dimension. It is impossible to know when and where the Rainbow Mist will appear. However, it appeared twice near Ruluka Island while no appearances in other places were reported.

Any ship who enters the Rainbow Mist is automatically transported to the dimension Ape's Concert (エイプスコンサート Eipusu Konsāto, Wrecker's Reef in the 4Kids dub) in which all ships and their crews and passengers are trapped when they entered the Rainbow Mist. It is called also a ship's graveyard because it is filled with wrecked ships. It is said that there are many treasures in this place.



Also, it seems this place is an eternal loop, which mean it takes anyone back to the point in which they started (though it does not seem to work so for purely inanimate objects without people, like the Tyriel which emerged 50 years after it entered the Rainbow mist. Also, Ian did not return to the past, but remained in the present). Time does not seem to pass here, or pass much slower then normally. However, by the time the Pumpkin Pirates entered the mist, none of all the previous prisoners were there. The reasons of their death are not clear, but it is possible that they were eaten by the Ruluka Sea King, a beast that was also trapped in the Ape's concert.

History
At some point of time in the late 1460s a marine ship commanded by Rapanui's Father entered the mist and was trapped there. Eventually, the entire crew died thre like the crews of all otherer sips before.



Around 1472 AOS the Pumpkin Pirates and Ian, a member of Whettons band of pirates wee trapped in the Rainbow Mist during whetton's attack on ruluka. For the next 50 years Henzo, the only member of the Pumpkin Pirates who stayed back on Ruluka researched the phenomenon in order to rescue his friends. Whetton, who became the mayor of ruluka sponsored his work.

A book series entitled Rainbow Mist, Volumes I through VIII was written around 1482 AOS. According to the book series, the Rainbow Mist should lead to the Land of the Gods called El Dorado. It also says that everyone who have looked for the Rainbow Mist and the Land of Gods never returned. Nico Robin purchased a complete edition of this books series in Arabasta shortly before she joined the Straw Hat pirates.



In 1522 AOS the Straw Hat Pirates visited Ruluka Island and met Henzo. On Ruluka Island, some of the Straw Hats make enemies of the Mayor and his men, who have placed high taxes on everything. Robin, Usopp, and Luffy meet Professor Henzo, who's doing research on the island's Rainbow Mist. When some of the mist shows up, Henzo borrows the Going Merry to go explore it. The Going Merry, with all crewmembers but Sanji, Nami, and Chopper aboard, gets caught in the Ape's Concert. They found out that the inside of the Rainbow Mist is full of wrecked ships and treasures, and is guarded by five kids. The kids are actually friends of Henzo's that got lost in the mist over 50 years ago. Henzo, his friends, and the others try to find a way out of the ship graveyard. Meanwhile, the Mayor and his men let the information about the Rainbow Mist slip to the remaining Straw Hats still on Ruluka. Luffy accidentally propels himself and Rapanui to the end of the mist. Nami appears in the ship graveyard with a rowboat full of treasure and a string connected to the real world, which are both stolen by Whetton's subordinate. The Mayor uses the Rainbow Tower to make a bridge to the Rainbow Mist. Due to the destruction of the Rainbow Tower, The mist collapsed. However, the Straw Hat Pirates and the Pumpkin Pirates managed to escape it's destruction, each crew returning to its own time period. The Going Merry escapes from the Rainbow Mist, getting badly damaged on the way. The Mayor gets arrested by a bunch of powerful marines that turn out to be older versions of Henzo's friends, who were thrown 50 years into the past by the Rainbow Mist's collapse.
