Keyblade Graveyard

The Keyblade Graveyard (キーブレード墓場, Kīburēdo Hakaba) is a world that is originally known as "The Badlands" (謎の荒野, Nazo no Arano; lit. "The Mysterious Wasteland"), before its formal introduction as a world.

"Beyond both light and dark he dwells, where war was waged upon the fells."
 * —Wizeman to Terra.

Overview
The Keyblade Graveyard is made up of unending, rocky badlands, scarred by the battles of the Keyblade War.

Settings
Early on, Terra and Ventus investigate the world at the Badlands (荒野, Areno; lit. "Wasteland"), where they run into Master Xehanort and Vanitas, respectively. Later, the Vanitas Remnant and Lingering Will appear here, where they challenge intruders to battle.

Each of the heroes eventually enter the true battlegrounds of the world at the Seat of War (古戦場, Kosenjou; lit. "Ancient Battlefield"), a small outcropping of rock overlooking the shattered vista below. It leads into the Twister Trench (砂嵐の道, Suna-arashi no Michi; lit. "Sandstorm Road"), where Vanitas's raging emotions have manifested as literal storms of Unversed. If any of the twisters are touched a battle against a group of Unversed begins. After this is the Fissure (峡谷, Kyoukoku), a small ravine containing a save point and Moogle Shop.

The final area, the titular Keyblade Graveyard are two crossroads, covered by the Keyblades of the wielders who fell during the Keyblade War. During his battle with the heroes, Master Xehanort creates a pillar of rock from the graveyard, and summons Kingdom of Hearts to shine down upon it.

After Master Xehanort steals Terra's body and is reborn as Terra-Xehanort, Terra's soul animates his armor as the Lingering Will, locks them both within the Will's Cage (思念の檻, 'Shinen no Ori), and forces him into a final battle. Meanwhile, Ventus and Vanitas have reunited into Ventus-Vanitas, and Ventus is forced to fight off Vanitas's control within Ventus's Mind (ヴェントゥスの精神世界, Ventusu no Seishin Sekai; lit. "Ventus's Soul World"). Both of these areas vanish after the battle ends.
