The Organiztion is the XIII Order, The Order's intentions are unclear even after the CoM has been released, Althought the Order seems to take an interest into the Keyblade Master Sora, They seem to be interested into Riku as well as all the weilders of the Keyblade.

No.4 - Vexen : No.4 in the Organization. A man absorbed in his dubious research in Castle Oblivion. He, Lexaeus, and Zexion have been in the group since its inception, and there is no love lost between them and neophytes like Marluxia. Vexen tried to destroy Sora by controlling Riku and putting the two against each other. After battling Riku, Vexen turns to events unfolding aboveground (he confronted Sora personally), but successive failures lead to his termination by Axel.

No.5 - Lexeaus : No.5 in the Organization. A born warrior, Lexaeus effortlessly brandishes a gigantic tomahawk. To counterbalance his rival Marluxia's bid for Sora's power, Lexaeus tried to conquer Riku. He failed, but with his dying strength dragged Riku into realm of darkness.

No.6 - Zexion : No.6 in the Organization. Zexion generally avoids dirtying his own hands when there are deeds to be done. However, with the destruction of Vexen and Lexaeus, he was forced into action. Zexion confronted Riku disguised as Sora. But Riku no longer feared dark, and victory was beyond Zexion's reach.

No.8 - Axel : No.8 in the Organization. A mysterious figure who stands in Sora's path.Hard to read, half the time Axel seems to just be messing around... but for all we know, he's done more thinking than everyone else put together. He is a shadow whose intentions and secrets are hidden from all. Axel has no qualms about exploiting others to suit his needs. He used Sora and Naminé to silence Marluxia and halt his plot against the Organization. Axel claims that he and Sora have something in common, but that connection is unclear.

No.11 - Marluxia : No.11 in the Organization. Lord of Castle Oblivion and a member of the Organization. Marluxia lured Sora to Castle Oblivion in hopes of using his power to seize the Organiztion. He ordered Naminé to alter Sora's memories, and fooled Vexen into challenging him. All was going according to plan, but Marluxia's scheme dissolved when Axel set Naminé free. Marluxia was ultimately destroyed by Sora. In a move to bring the group under control, Marluxia used Naminé to overrun Sora's memory and tried to claim the power of the Keyblade.

No.12 -Larxene : No.12 in the Organization. Larxene is unfeeling and loves nothing more than to bring other people down. She is on good terms with Axel but still mocks everyone and trusts no one. Larxene conspired with Marluxia to take over the group, and intended to pull Axel in as well. However, her abrasive, unfeeling personality proved her downfall- provoking Sora's anger was a fatal error.
