Castle Oblivion, often abbreviated as "C.O." by members of Organization XIII, is a world introduced in Kingdom Hearts Chain of Memories. It is located within the Realm Between, though a digital copy of the world appears in Kingdom Hearts coded. It was governed by Marluxia, and consists of thirteen floors and twelve basements. After Marluxia's defeat, the Organization abandoned the castle as they lacked the manpower to keep it operational. Hidden within the castle is the Chamber of Waking, where Ventus sleeps; no one but Aqua can locate the Chamber, as she was the one who designed the layout of the castle to keep Ventus safe.

Journal entries[edit]

Kingdom Hearts Chain of Memories[edit]

Sora's Tale I

Our friends may be here...It was that thought that led us to Castle Oblivion, where cards rule all.

A mysterious man gave Sora a card, and using it took us to Traverse Town—of all places!

It turned out the town was just a figment of our own remembrances, the first world of many that lie in Sora's heart.

And so our journey through these worlds begins.

Settings and Areas[edit]

In Kingdom Hearts Chain of Memories, Sora and Riku create the layout of Castle Oblivion themselves from their memories of the worlds they have visited (except Deep Jungle for both characters and the 100 Acre Wood for Riku), using Map cards. There is also an Entrance Hall (入口ホール Iriguchi Hōru?) and Exit Hall (出口ホール Deguchi Hōru?) for each floor. Additionally, Sora slept in his Memory Pod within the Pod Room (ポッドルーム Poddo Rūmu?).

In Kingdom Hearts coded, Data-Sora arrives in the Entrance Hall, which contains a large door that allows Data-Sora to access re-imaginings of worlds, including Destiny Islands, Traverse Town, Wonderland, Olympus Coliseum, Agrabah and Hollow Bastion. Data-Sora battles Data-Roxas in the Station of Sorrow (悲しみの園 Kanashimi no En?), a platform of stained glass disconnected from the rest of the world.

Story[edit]

Kingdom Hearts Birth by Sleep[edit]

Aqua in front of Castle Oblivion.

Castle Oblivion was originally the Land of Departure. After the events at the Keyblade Graveyard, Aqua brought a comatose Ventus to the Land of Departure, which had been destroyed in a storm of darkness by Master Xehanort. In order to keep Ventus safe, Aqua follows Eraqus's prior instructions to seal the world's Keyhole with his Keyblade and recreate it as a labyrinth that only she could navigate, using a means devised by prior guardians. She leaves Ventus in the castle's newly-formed Chamber of Waking and promises to bring Terra back with her before waking him up. As Aqua leaves to search for Terra, she looks back on her transformed home.

Between Kingdom Hearts Birth by Sleep and Kingdom Hearts Chain of Memories[edit]

The castle is eventually discovered by Xemnas of Organization XIII, who decides to convert it into a second headquarters for the Organization. It is intended to be a place to research memories, an important topic to the Nobodies of the Organization, who have only their memories with which to form personalities. Xemnas sends Xigbar and Xaldin to recruit more members for the Organization, as they need a large group in order to run the castle. Despite rumors among the Organization that Xemnas intends to locate the Chamber of Waking, to complement the Chamber of Repose built under Hollow Bastion, they never do.

Eventually, a strange Nobody named Naminé appears in the castle and is found by the Organization. She soon becomes the center of their research, due to her strange abilities of memory manipulation. In order to further research, pods are developed that can be used to piece together memories. Xemnas entrusts the castle and Naminé to the neophyte Marluxia, but the latter soon plots to use this power in a bid to seize control over the Organization. While Marluxia and his associates, Larxene and Axel, control the top half of the castle, the senior members Vexen, Lexaeus, and Zexion control the basements.

Kingdom Hearts Chain of Memories[edit]

After defeating Ansem, Seeker of Darkness, and restoring the damaged worlds, Sora, Donald Duck, and Goofy find themselves in a grassy field with the King's dog, Pluto. They follow Pluto along the path to Castle Oblivion, and as soon as they enter the castle, they forget all of their skills and are forced to rely upon the castle's memory-based card system. Although Marluxia and Larxene tell them their memory loss is simply the nature of the castle, it is revealed that the mysterious girl Naminé is actually the one reshaping Sora's memories, so that Marluxia can use Sora as a puppet against Xemnas. The scheme fails thanks to the meddling of Axel (who was actually on orders from Xemnas and Saïx to rid the Organization of traitors), who frees Naminé, and Marluxia and Larxene are destroyed at Sora's hand. Sora then uses one of Xemnas's pods so that Naminé can restore his memories, and is eventually moved to Twilight Town.

Meanwhile, Sora's friend Riku awakens from the darkness within the lowest basement of Castle Oblivion, where he faces the remaining darkness of "Ansem". Though he initially sets out to destroy the indelible darkness in his heart, with the help of DiZ, Naminé, and King Mickey, he is able to eventually embrace both the light and the dark, achieving balance. The three basement members, Vexen, Lexaeus, and Zexion seek to recruit Riku in order to counter Marluxia's use of Sora, but Riku denies their requests and vanquishes them. Riku eventually defeats the Ansem in his heart, and decides not to have Naminé seal it away completely; instead, he sets out on the "road to dawn" in order to help while Sora is sleeping.

Kingdom Hearts 358/2 Days[edit]

After members of Organization XIII are sent to Castle Oblivion, Roxas learns from Demyx and Xigbar on Day 24 that the members assigned to Castle Oblivion have been annihilated.

On Day 255, Axel went in Castle Oblivion to get rid of any evidence of the Organization's presence as the castle would no longer be used as a research facility/second headquarters. Xion goes to Castle Oblivion on the same day to seek answers about her existence. Axel tries to stop her, but his efforts are futile.

On Day 296, when Roxas learns from Axel that Xion was born in Castle Oblivion, he becomes determined to investigate the place for himself. The next day, Roxas was assigned to go there and hunt down the impostor. Roxas used the opportunity to investigate Castle Oblivion. Axel chose to tag along claiming that he knows the place better than anyone else in a black coat. However, barely has Roxas walked in the door when he is overcome by a strange weakness and passes out entirely, due to how close he physically was to Sora and Ventus.[1]

During conversations between Axel and Saïx, Saïx asks Axel if he has found the Chamber of Waking, which Axel denies. Axel is sent various times by Xemnas to find the room, showing Xemnas's extreme determination to find the Chamber of Waking, yet he never succeeds, due to Aqua's previous actions.

Kingdom Hearts II[edit]

Roxas briefly sees the outside of Castle Oblivion in his final dreams, coinciding with Sora regaining the corresponding memories.

Kingdom Hearts coded[edit]

After defeating Sora's Heartless and returning to the data worlds, Data-Sora enters a data version of Castle Oblivion. He has meetings with the mysterious cloaked man, as well as various figures from Sora's memories. Like the real Sora did, Data-Sora uses World Cards to traverse the castle. One notable feature of this incarnation of Castle Oblivion is that the White Rooms do not change form completely; the design remains like the rest of the castle, although the shape of the room differs. Pictures of areas from the worlds are displayed on the walls. Near the end of the story, he meets Data-Naminé, who explains the reason of his existence.

Kingdom Hearts 3D: Dream Drop Distance[edit]

Ventus continues to sleep within the Chamber of Waking, following the end of Sora and Riku's Mark of Mastery exam. Upon Sora's return to Traverse Town, he smiles from Sora's happiness.

Trivia[edit]

  • The need for the card system in Castle Oblivion is unknown. Although Marluxia claims that they are simply part of the castle, he also claims that the trademark memory loss was due to the castle's influence as well, when in actuality it was Naminé's doing.
  • In the manga, the monitors through which the Organization watches Sora are "Nomura-brand", a reference to Tetsuya Nomura, the director of the Kingdom Hearts series.
  • The Castle Oblivion logo depicts stairways that resemble those of M.C. Escher's Relativity.

Notes and references[edit]
