The Reverie (literally translated as "World Council") is a council formed by the World Government which consists of the world's greatest leaders of various kingdoms.
Meetings are held every four years at Mariejois and kings or queens gather to discuss matters that could affect the world.
As this is a meeting of leaders of nations, a full scale war could be initiated if one king simply insults another. An example is when Wapol purposely hit Nefertari Vivi as an act of revenge against her father, Cobra, after he scolded Wapol for his selfishness. Due to Vivi's and Cobra's kindness, they did not retaliate with war, and Wapol was simply angry and left. The possibility for conflict is heightened due to the extreme range of viewpoints among the kings.
Eight years ago, participants discussed Dragon and his actions, stating that within four to five years he would be a major threat to the World Government. This caused a conflict between Nefertari Cobra and Wapol when Wapol would not take the threat seriously.
16 years ago, Queen Otohime, in an effort to get Fishmen and Merfolk to grow closer to Humans, made a proposal to relocate Ryugu Kingdom to the surface. She wanted to present this wish at the Reverie that year, and asked her kingdom's citizens for signatures.
15 years ago, King Neptune stated that he would not be allowed to attend the next Reverie due to the recent incident of Fisher Tiger raiding Mariejois and liberating slaves, which caused Fishman Island's standing to fall.
10 years ago, Otohime went to Mariejois and returned with an official letter from a World Noble, supporting her cause to relocate Ryugu Kingdom. She stated that the plan could be realistically put into action if enough signatures are collected by the next Reverie.
8 years ago, a Reverie was held, with the participants including Thalassa Lucas, Nefertari Cobra and Wapol. During the meeting, Lucas brought up the Revolutionary Dragon, labeling his ideologies "dangerous" and stating that he would become a great threat to the World Government in 4-5 years. Wapol disregarded this as not concerning his country, which prompted Cobra to scold him for his irresponsibility. After the meeting Wapol came across Cobra's daughter Vivi and purposefully hit her as revenge against Cobra. Vivi, however, simply apologized in order to avoid conflict between their countries.
Over 50 countries ruled by royal families are planning to attend this year's meeting. Among them are the Nefeltari Family of Alabasta, Stelly and his wife, Sarie of Goa Kingdom, Wapol and Miss Universe of Black Drum Kingdom, Dalton of Sakura Kingdom, the Riku Family of Dressrosa, Elizabello II of Prodence Kingdom, and the king of Kano Country.
