End of the World

The End of the World (エンド・オブ・ザ・ワールド) is a World from Kingdom Hearts. It is the last new location to open in the game, upon locking Hollow Bastion.

Arguably the most sinister and ominous area in the series, End of the World is a by-product of the Heartless' destructive nature. Although End of the World is the last world, the Heartless are not very numerous as compared to Hollow Bastion but they are very powerful. Upon taking a world's heart, a tiny fragment of what is left of that world is sent drifting through the void of space until it eventually meets and merges with End of the World. It is, in essence, a Heartless of the destroyed worlds, as well as the location of Kingdom Hearts for worlds' hearts. In nature, it can be seen as the opposite of The World That Never Was, which is a similar artificial "Nobody" world without its own heart.

The theme music for End of the World is "End of the World" and the battle theme is "Fragments of Sorrow". Both are arrangements of different segments of "Dive Into the Heart (Destati)", the music used during the Awakening.

Setting
End of the World opens on the Gate to the Dark, a sea of darkness in the process of collapsing. Along the snowy fragments of landscape are a few battles against Behemoths (turned into Arch Behemoths in Kingdom Hearts Final Mix) and other high-level Heartless. Following the empty void is a colorful, quiet canyon that is called the Giant Crevasse that spans several levels connected by green web-like formations. At the bottom of the canyon is a passage to the fragmented World Terminus, which in turns leads to the Evil Grounds and a boss battle with Chernabog.

After defeating Chernabog, the top of Bald Mountain opens, allowing Sora and his party to descend through the Volcanic Crater. This leads to the bottom of the mountain, where a hard and well-fought journey through the Linked Worlds room leads to the Final Rest, where the final save point of the game is, as well as The Door, first seen in the Awakening, that leads to the final confrontations of the game. It should be noted that Atlantica, Olympus Coliseum or even Monstro doesn't have to be completed in order to access this world.

Evil Grounds
Also known as Bald Mountain because of the background music while fighting Chernabog is called "Night on Bald Mountain". You can fly in this area and you can drop into the crater to proceed. Once you enter the crater at the bottom there will be an entrance to a tunnel that leads to the cave of Final Rest where the Door to Darkness is located. On the way through the tunnel, remnants from different worlds can be seen attached to the walls such as, trees and small towers from Sleeping Beauty, the horrific trees and the front door of the Dwarfs' house from Snow White, stone tapestries from Cinderella, and Beast's Castle is seen in a small sphere attached to the wall. Though Bald Mountain appeared in Fantasia and Chernabog was a resident of it, it is unknown what role it really plays for the Kingdom Hearts series besides leading to the Final Rest.

Kingdom Hearts
After sealing the Final Keyhole at Hollow Bastion, Sora, Donald, and Goofy arrive at the End of the World. Goofy takes note of its composite-world nature, and Sora states that all of the worlds would be restored if they managed to defeat Ansem, but wonders what would happen to the world itself and them by extension. Goofy says that, as a "Heartless world", it would just disappear, but assures them that, even if that did happen, they would not meet the same fate. Sora takes out Kairi's lucky charm, and remembers his promise to return it.

After fighting through several legions of Heartless and the World Terminus, Sora, Donald, and Goofy run into the giant demon Chernabog and manage to defeat him after a lengthy battle. Afterwards, they descend into the crater of Bald Mountain and press onwards. Eventually, they come to the remnants of Sora's homeworld, the Destiny Islands, which soon takes on a much darker appearance.

Ansem appears in the form of Riku, and states that Riku was desperate to escape the islands by any cost, and then takes on his own form. Sora calls out to Riku, but Ansem informs him that any effort to reach him is futile. The villain goes on to explain that all worlds and hearts begin and end in darkness; thus, darkness is the true essence of a heart. Sora denies this, stating that, while hearts may be weak and sometimes even give in, deep down, there is a light that never goes out. Unimpressed, Ansem says, "So you've come this far, and still you understand nothing" (mirroring his words to Sora at the beginning of the game), and engages in battle with the trio.

Sora comes out victorious, and then the mountains of the islands split open. Ansem escapes into the opening with Sora, Donald, and Goofy in hot pursuit, but only Sora is able to get past a preset barrier. After defeating another Darkside and Ansem, the latter uses his power to send himself and his foes to a dark void.

Ansem fuses himself to the World of Chaos, a giant, semi-organic Heartless battleship, and sucks Donald and Goofy into a Portal of Darkness. Sora begins to fall into the void, but the encouragement of Riku gives him the strength to fight back. Sora rescues Donald and Goofy, and the trio destroy the World of Chaos.

Badly injured, Ansem opens the Door to Darkness, informs Sora that not even the Keyblade can seal the door, and pines for Kingdom Hearts to fill him with the power of darkness. Sora shouts that Kingdom Hearts is, in fact, light, which proves to be correct; the light of Kingdom Hearts shines out of the door and hits Ansem full force, destroying him.

However, the threat is not over; several thousand Heartless lie in wait behind the door. Sora, Donald, and Goofy attempt to close it, but even with help from the restored Riku, their efforts are futile. Just when things appear to be over, King Mickey arrives with a golden Keyblade, and Sora, Riku, Donald, and Goofy manage to close the door. Before it does, Mickey assures them that there will always be a door to light; thus they will be able to find their way back. Riku asks Sora to take care of Kairi, and Sora and Mickey use their respective Keyblades to seal the Door to Darkness forever.

Soon afterwards, Kairi appears, and Sora runs off to talk to her. However, the worlds are beginning to restore themselves. Sora promises to return to Kairi when his obligations are done just as the End of the World breaks apart; Kairi is sent back to the Destiny Islands alone, while Sora, Donald, and Goofy end up on the pathway to Castle Oblivion (as revealed in Kingdom Hearts: Chain of Memories).

Trivia

 * If you look at the wall in the second part of the path to the Linked Worlds section, you can see what looks like part of the forest in Enchanted Dominion, as well as pieces of what looks to be Castle of Dreams and Dwarf Woodland.


 * Coinciding with the End of the World being the opposite of the World That Never Was, the End of the World seems more naturistic whilst the World That Never Was seems more industrial. This could coincide with the fact that Nobodies, as opposed to Heartless, rely on intelligence rather than instinct whilst Heartless are vice versa.


 * The End of the World is one of five worlds in Kingdom Hearts not based on a Disney movie, the others being Destiny Islands, Hollow Bastion, Traverse Town and Disney Castle (the latter was Disney themed but not based on a specific movie).


 * In the Green Room in the Traverse Town hotel, you can see a painting called Bald Mountain: 7:00 A.M. - this is a likely reference to Evil Grounds in the End of the World.


 * If you wish to get out of Evil Grounds, you need to fly up until you reach the World Terminus
