Jail Island

Jail Island is the main setting of the game One Piece: World Seeker. It is under the control of the Marines. It was formerly called Jewel Island (ジュエルアイランド).

Layout and Locations
Jail Island is a lush, green island with multiple elevated surfaces and precious stone formations. It is stated to be rich in natural resources. It is divided in five zones, each of them with at least one main city. Moreover there are three prisons, built up by new Warden Isaac, and several Marine Bases.

Steel City
Steel City (スチール街) is the largest and most populous settlement on Jail Island. It is located on the east coast of the island near the center, being bordered by Halcum Port to the north and Suisho Canyon to the south. The main Marine base of the island is located directly adjacent to the city off to the east, while a bridge connects the city to the Sea Prison from the southeast. Steel City possesses uniquely tall skyscrapers and colorful electronic images. Notable areas within the city include the downtown area which features an open-air marketplace, as well as the "slums" directly west of the Marine base which criminals and Anti-Navy faction members can be found in. Due to the town's population and its close proximity to many locations, particularly Marine-controlled areas, it is often the best place to find and collect information.

Sogyoku Town
Sogyoku Town (ソーギョク町) is a town located to the west of the island, directly north of Kohaku Harbor. Given its proximity to the pirate-infested harbor, it is frequently a target for pirates. The town also has a large Anti-Navy population, with the faction's leader Jeanne living in the church there. However, there is also a small Marine base directly adjacent to the east.

Suigyoku Town
Suigyoku Town (スイギョク町) is the farthest-north town on the island, being located directly northwest of Konko Plaza and northeast of Hisui Bridge. The Marines stationed on the island currently make up most of its population, with their occupation causing the vast majority of civilians to move elsewhere. The only civilians that live there are Omusubi and her children, with Omusubi working as a lunch vendor for the Marines.

Ogyoku Mine Town
Ogyoku Mine Town (オーギョク鉱山町) is a town located northeast of Sogyoku Town. Nestled right against Ogyoku Mine to the south, its population consists heavily of miners. However, they are no longer able to mine from Ogyoku Mine due to the Marines taking control of it and barring access, which has created tensions among them.

Kogyoku Village
Kogyoku Village (コーギョク村) is a village located on the northwest side of the island, directly south of the Prison Tower and northwest of Hisui Bridge. It possesses a harbor, although pirates have been shown to use it.

Kohaku Harbor
Kohaku Harbor (コハク港) is a harbor town located on the southwest side of the island, southwest of Sogyoku Town. The Thousand Sunny was docked here during the Straw Hat Pirates' trip to the island. It is infested with pirates, with some being friendly while others are hostile and will attack on sight.

Halcum Port
Halcum Port (ハルコンポート) is a port located at the very northeast edge of the island, directly north of Steel City. It is a quite industrialized area that specializes in cargo shipping and other official travelers, although pirates have been seen there as well. On its west side is a "warehouse town" where people presumably reside.

Konko Plaza
Konko Plaza (コンコー広場) is a large stone plaza located northwest of Steel City and southwest of Suigyoku Town. When Isaac and Jeanne's mother was leader, it was a place where many residents congregated and socialized. Following their leader's death and the start of the Marine occupation, people stopped coming around for the most part. However, thanks to Luffy and Jeanne's work to get the islanders to reconcile, people started congregating there again. It was the site where Jeanne tried to prevent a war between Pro-Marine and Anti-Marine factions from breaking out.

Hisui Bridge
Hisui Bridge (ヒスイ橋) is a three-part bridge connecting the north, northwest, and southwest portions of Jail Island together. The three bridges converge on a small island, which a Marine checkpoint is located on. The bridge is guarded and patrolled by Marines at all times.

Ogyoku Mine
Ogyoku Mine (オーギョク鉱山) is a mine located within the lone mountain on Jail Island. The mine contains a great many precious gems and used to be freely mined by Jail Island's citizens; however, following the Marine occupation, the Marines took full control over the mines and barred civilians from entering them.

Suisho Canyon
Suisho Canyon (スイショー渓谷) is a cape located on the southeast corner of the island, directly south of Steel City. It is lined with a great number of plateaus overlooking crevices below; there are many caves in the elevated ground areas containing precious gems as well as many large gem formations aboveground. Like Ogyoku Mine, it has been fully taken over by the Marines and civilians are currently prohibited from entering it.

Battery Island
Battery Island (砲台の島) is a small forested cape that juts out west from Halcum Port. Although once a popular place for children to play, it has since become infested with pirates over the last decade, with Don Axe having the most power over it.

Graveyard
The Graveyard (墓地) is located to the east of Ogyoku Mine Town, and sits atop cliffs overlooking the shores and water below. It contains numerous burial sites and gravestones, one of which is that of the island's previous leader. The Graveyard is tended to by Hakamori.

Spa Island
Spa Island is a little island in the sea zone near Amber Harbor, characterized by a constant steam, similar to fog. It hides a secret onsen.

Sky Islands
There are two islands in Jail Island's skies. Both are under pirates' control, setting as their main base.

Sky Prison - Santamaria
The Sky Prison - Santamaria ("空中監獄" サンタマリア) was the first Marine prison shown. It was a giant flying machine which housed a large prison complex. The Straw Hats infiltrated this prison under the impression that a treasure was located here, but found that there was none and that it was a trap. Later, Isaac intended to fly the Sky Prison into Mary Geoise while it was loaded with Dyna Stones in order to destroy the Holy Land. However, his fight with Luffy caused the prison to lose power and descend into the sea not far from Jail Island, where it was destroyed in a massive explosion.

Sea Prison - Aquamarine
The Sea Prison - Aquamarine ("海中監獄" アクアマリン) is the second Marine prison to be revealed. It is a large, mostly underwater complex located on a small island to the southeast of Steel City connected by a long bridge. The prison has six descending levels in a manner very similar to Impel Down, all of which are submerged in water. In order to drain a level and descend into it, one must activate a switch on the level above. Marine guards are seen stationed on all levels but Level 6, though it is not clear how they can stand guard when the levels are underwater most of the time. Franky was imprisoned here but was quickly freed after a break-in by Luffy.

Prison Tower - Tormaline
The Prison Tower - Tormaline ("監獄塔" トルマリン) is the third Marine prison to be revealed. It is a large tower constructed out of metal located directly adjacent to Kogyoku Village. It is kept within a conventional stone wall and guarded by a Marine barricade. Its front entrance is just about impenetrable against invaders; however, its roof is open and people can enter it by climbing up platforms attached to its exterior at steady intervals, although Marine guards are also stationed on gondolas hanging down from the tower. The interior of the tower is an open space with spaced-out jail cells built as independently-standing mini-towers. Nico Robin was imprisoned here but was quickly freed after a break-in by Luffy.

Factions
After the Marines began occupying Jail Island under Isaac, two factions formed among the islanders: the Pro-Marine Faction (海軍派) and Anti-Marine Faction (反海軍派). The Pro-Marine Faction consists mainly of people who value the increased safety the Marines have provided or who benefit from the economic gains created by the prison construction. The Anti-Marine Faction mainly consists of people who did not benefit from the building of the prisons, those who view the Marines' presence to be unnecessary, and those who consider the Marines to be corrupt or untrustworthy.

These opposing viewpoints have devolved into outright hatred between some members of these factions, with these people often treating those in the other faction as stupid and hurling personal attacks at them. Families belonging to a faction have been known to even keep their young children from playing with children of families in the other faction, and keep older children from dating members of families in the other faction. While the Anti-Marine Faction mainly protested the Marine occupation peacefully as their leader Jeanne desired, they also stockpiled weapons in preparation for a potential war against both the Marines and Pro-Marine Faction. This inclination toward eventual violence was shared by the Pro-Marine community, and things came to a head when a Pro-Marine fired a gunshot at a few Anti-Marines in Sogyoku Town, resulting in a brief civil war although the fighting managed to be quelled rather quickly by Jeanne and the Straw Hat Pirates.

This division was subversively encouraged by Isaac in order to start a civil war that would distract several global powers and allow him to successfully destroy Mary Geoise. He possessed resentment for both sides, considering the Pro-Marines to be lazy oafs coasting on the economic benefits provided by the Marines while the Anti-Marines are all cowards who have no intention of seriously fighting against the occupation. With the work of Jeanne and the Straw Hats, many of the islanders have begun learning to put their blind hate aside and talk about their differences civilly; it is not known what the attitudes of the factions are like currently or if they still exist at all.

Past
Sometime in the past, the inhabitants began to extract Dyna Stones using a secret method of excavation known only to the leader of the island.

Twelve years before the main storyline, the Marines hired a pirate fleet to attack the island in order to obtain the excavation method and the Dyna Stones, acknowledging them as a huge threat to world power balance. Thanks to Jeanne's mother, the war was averted, but she lost her life in a fight. The only survived pirate is Barbados.

Some time later the future leader and Jeanne's brother Isaac left the island in order to enlist in the Marine to pursue his justice ideals. He eventually lost faith in the Marine finding out the truth behind pirates attack to the island, but keep ranking up till the Prison Warden position, just to make return on the island, officially in order to monitoring the Dyna Stones excavation and sending information to the Headquarter. He made build other two gaols (Aquamarine and Santa Maria), which brought richness to the people supporting Marine's domination, while the ones opposing them got ostracized by various power abuse episodes, factually splitting the population in two factions: Pro-Marines and Anti-Marines. Jeanne eventually became the Anti-Marines' leader.

Isaac secretly began his revenge plan ten years before the main storyline, when he gathered a huge number of pirates in Tormaline, forcing them to build mechanic parts.

Some time before the main storyline, Isaac began spreading the rumour about a hidden treasure on the island, in order to gather several pirates to obstruct CP-0 agents' investigation and to draw the Marine Admirals' attention.

One Piece: World Seeker
Following the rumor about the treasure, Straw Hat Pirates reaches Jail Island short before the begin of the arc. The same goes for both Buggy and Crocodile. Almost at the same time, the World Government began to seek information, sending Rob Lucci on the island. Germa 66 too got convoked on the island due to their interest into buying Isaac's robots. Even Katakuri appears to be interested in Dyna Stones.

The grown grudge between Pro-Marines and Anti-Marines lead the latters to ask for Revolutionary Army's help, but it is too late. Short later Sabo's arrival on the island, some Pro-Marines shoot on Anti-Marines and civil war spreads.

Jeanne is able to appease the civillian thanks to a message spred by the Radio Tower she assaulted with Straw Hat Pirates' help. Isaac decides to make his move invading the island with his robots, keeping busy both admirals Kizaru and Fujitora as Kuzan, Smoker and Tashigi. Luffy and Jeanne decides to reach Santa Maria to personally deal with Isaac, but Fleet Admiral Sakazuki gets in the way. Thanks to Sabo's intervention, both Luffy and Jeanne are able to reach the cannon that will send them on the Sky Prison.

On the Santa Maria, Isaac reveals his true intention: he wants to launch the prison on Mary Geoise, letting the Dyna Stones collected in there explode, destroying the Holy Land. After Isaac's defeat, the prison detonates far from Jail Island. The shockwave invests the island, inducing Marines to evacuate the residents.

Some time after Straw Hat Pirates's departure, the island is back to normality and Jeanne visits her mother's grave, discovering Isaac is still alive.
