Not based on a Disney film, though showing Disney influence such as the Beast's haunted castle from the movie, Beauty & the Beast, and Maleficent's fortress from the Forbidden Mountain from the film, Sleeping Beauty, Hollow Bastion is a colossal castle that towers above the rest of its world, Radiant Garden. At one point, it was the only remaining part of the world, along with the waterways beneath it. Because of this, the world itself was known as "Hollow Bastion" in Kingdom Hearts, Kingdom Hearts: Chain of Memories, and most of Kingdom Hearts II. However, it regains its original name of Radiant Garden by the end of Kingdom Hearts II, when Tron used his powers to show what the world was like before its destruction.|final state = Transforms back into its original state (Radiant Garden)}} Unlike the rest of the Radiant Garden, which poses as Final Fantasy's world, Hollow Bastion has no relation to Final Fantasy whatsoever.

Between Kingdom Hearts Birth by Sleep and Kingdom HeartsEdit
Hollow Bastion was once a glorious castle towering over the Radiant Garden and owned by a respectful king, Ansem the Wise. Much of the history of the castle is unknown, other than that Ansem ruled from it. However, eventually Ansem's apprentices led by Xehanort overthrew their former mentor, and remodeled the castle to include mechanical components. The result was a twisted bastion; half beautiful castle, half distorted factory. According to Leon, Maleficent invaded Hollow Bastion's world with her Heartless nine years before the events of Kingdom Hearts. Some residents managed to escape, many of whom ended up in Traverse Town. However, the youngest known resident, Kairi, was sent into the oceans of the worlds by Xehanort and ended up in Destiny Islands. During her reign in the castle as one of Ansem, Seeker of Darkness's minions, it is probable that Maleficent either created or remodeled the castle's keep, which has decorations and models of roses and her thorned plants.
Sora, Donald and Goofy arrive at Hollow Bastion in time to find Riku attacking another intruder, the Beast. Sora, Donald, and Goofy confront Riku, but he declares he is the Keyblade's true holder; it jumps into his possession, leaving Sora defenseless except for his old wooden sword. Shocked at this revelation, Sora collapses to the ground. Riku departs, and Donald and Goofy, having been ordered to follow the Keybearer, reluctantly follow him. The Beast staggers on despite his injuries, and Sora quickly gets over his shock to help him. The Beast reveals that he is looking for someone important to him, and refuses to depart without her. Sora, sympathizing, takes up his old wooden sword, and the two team up to enter the castle.
After traversing the castle waterways to unlock the main door, Sora and Beast enter Hollow Bastion. Beast witnesses an illusion of Belle transforming into a Heartless, and, enraged, jumps at the Heartless, with the doors slamming shut behind him. Riku, Donald, and Goofy appear soon after, where Riku orders Sora to give up, though Sora refuses to leave without Kairi. Sora informs Riku that while the darkness may destroy his body, it can't harm his heart, and Riku decides to test Sora's theory by firing a dark energy bolt at him. Sora, believing it to be the end, braces himself, but Goofy rushes in and blocks the blast with his shield. After being questioned by Riku, Goofy swears that he will never betray King Mickey, but won't betray Sora after all that they have been through together, and asks Donald to apologize to the King for him; however, Donald also chooses his friendship with Sora over King Mickey's orders and rejoins Sora. Sora informs Riku that he doesn't need the Keyblade; his friends and heart are the only weapons he needs. Sora's strength of heart with his friends back by his side pulls the Keyblade away from Riku and back to him. After a fierce battle, Riku is defeated and flees. Beast rejoins the party after watching the encounter, observing that Sora's heart was what helped him win.
Riku is upset at losing the Keyblade, but encounters Ansem, Seeker of Darkness, who promises him that he can make Riku's heart stronger through darkness and allow him to regain possession of the Keyblade. Jealous and angry at Sora and shamed over his loss of control of the Keyblade, Riku succumbs to his pledge and powers, and becomes consumed by the darkness. In the meantime, Maleficent has attempted to use the gathered Princesses of Heart to open the Bastion's Keyhole. The Heartless-possessed Riku meets with her to check her progress, where Maleficent declares she will control and use the darkness for her own purposes; however, neither she nor Ansem-Riku can unlock the Keyhole without Kairi's missing heart.
Sora and friends manage to travel through the labyrinth of a castle to reach the chapel; there they meet with and confront Maleficent. Overconfident in her abilities and underestimating those of Sora's gang, she is soundly defeated. Escaping back to Riku for help, she is stabbed through the heart by his Keyblade of People's Hearts, made from the hearts of the six Princesses. It unlocks the darkest parts of her heart and allows her to transform into a large, powerful dragon; however, Sora's party defeat her again, and she is consumed and burned away by the darkness. Riku then appears and reveals that Maleficent was merely a pawn of the Heartless, unable to see the darkness swallowing her heart. He then departs and Sora and company travel to the Grand Hall, where the Keyhole and Princesses are located, to find and confront him. There, Sora finds Kairi unconscious on the floor in front of the partially opened Keyhole. He tries to wake her, but Riku appears to tell Sora her heart is missing. Riku continues to tell Sora that Kairi is one of the princesses and that her heart is within him. Sora is able to realize that Riku is no longer in control of his own body. Riku knocks both Donald and Goofy back behind a preset barrier, and Kairi's heart reacts to the Keyblade of People's Hearts' power, causing Sora crippling pain. Xehanort's Heartless then attacks him, but Sora recovers and blocks the strike in time. After an intense battle over who would possess Kairi's heart, Sora emerges victorious.
Riku disappears, but the Keyhole begins reacting to the presence of Kairi's heart. Sora attempts to lock the Keyhole, but without Kairi's heart, it is not complete and cannot be sealed. Sora puts two and two together and realizes what he has to do; despite Donald and Goofy's desperate pleas, Sora stabs himself with the Keyblade of People's Hearts left in Riku's wake, releasing all of the princesses' hearts (including Kairi's) and completing the Keyhole, but Sora falls into darkness himself.
Kairi wakes just in time to see Sora disappear. As Kairi, Donald, and Goofy mourn the loss of Sora, Ansem, now in full possession of Riku's body and having shaped it into one resembling his original human self, reappears, declaring that Kairi's purpose is over, effectively deciding to kill her. Donald and Goofy bravely make a stand against Ansem, but both know that, without Sora, they may not be able to stop him. However, before Ansem can attack, Riku projects himself from his stolen body, manages to establish enough control to stop him in his tracks, and warns Kairi and the others that the Heartless called by Ansem will soon overrun the castle at which they heed and run to escape. The three return to the entrance, and hesitate due to Kairi's reluctance to leave Sora and Riku behind; Goofy himself is still concerned about the Keyhole (apparently failing to realize that, without Sora and the Keyblade, the Keyhole cannot be stopped). An apparently non-hostile Heartless arrives; Donald shouts at it to get lost and whacks it over the head with his staff, but Kairi realizes that the Heartless is, in fact, Sora. At that moment, massive legions of Heartless attack, and swarm Kairi and Sora's Heartless, much to Donald and Goofy's horror. However, a brilliant flash of light blows the Heartless back, and in place of the Heartless, there is Sora, fully restored. Beast stays behind to hold off the Heartless and continue looking for Belle, and so the group departs Hollow Bastion.
Cid manages to find a way to allow them to return and seal the Keyhole. They return and help Beast reunite with the re-awakened Belle, and jump through the Keyhole to fight a Behemoth Heartless. After a conversation with Leon's group, who have returned to restore their home world, Sora seals the Keyhole at Hollow Bastion.
In the Kingdom Hearts Final Mix version, Sora also has his first encounter with Organization XIII in the chapel by way Xemnas, here known only as "Unknown". After some cryptic messages (such as stating that Sora is incomplete and looks just like "him"), Xemnas departs. It is revealed in Kingdom Hearts II that this battle takes place shortly after Xemnas recruited Roxas into the Organization, and he fought Sora to test his abilities.
Kingdom Hearts: Chain of MemoriesEdit
In Sora's story, Hollow Bastion is also recreated as a figment of his memory. It is where the Beast, Belle, and Maleficent which were created from his memory are, and Belle is denying her love for the Beast and Sora has to defeat Maleficent in her Dragon form. But opposed to the first game, it focuses more on the relationship between Beast and Belle.
In Riku's Story, Hollow Bastion is recreated inside Castle Oblivion as a figment of his memory. It is the first world he enters and fights a memory recreation of Maleficent in her Dragon form.
