Kingdom Hearts
This world is the staring world for Link's storyline in KH: A New Beginning (aside from the Awakening "tutorial" level), and the home of Link, Zelda, a young Ike (from Fire Emblem: Path of Radiance), a young Tifa (from Final Fantasy VII), a tennage Basch (from Final Fantasy XII) and Vaati (but he is a good guy, at first). When Vaait opened a door to darkness in a part of the village where Link lives, he plunges the world into darkness. Zelda is kidnapped, Vaati vanishes, and Link is thrown into Ivalice after fighting a evil chameleon Heartless known as Stealth Sneak. A "mirage" hybrid (w/ Destiny Islands (Sora's home world)) version of this world appears in the End of the World area. In KH II: The Adventure Continues, the world appears in the dreams of Klixn, and in cutscenes, but will not be a playable world.
