Once upon a time, a young boy named Sora was transported from his home in the Destiny Islands and into the universe called "Kingdom Hearts." Upon his arrival, he discovered himself to be the possessor of the "Keyblade," a powerful weapon that was created for the purpose of defending Kingdom Hearts from the forces of evil. Deemed the "Keybearer," Sora traveled with two of the King's most loyal subjects in a quest to Seal each World's "Keyhole," thereby preventing the invasion of the "'Heartless," beings who wished to use the powers of Darkness to corrupt the Worlds. He succeeded, and all the Worlds reformed and celebrated the fall of the Darkness.
The peace brought about by Sora's valiancy was only temporary. One year later the Darkness returned, this time in the form of the "Nobodies," beings with the ability to wreak even greater havoc due to the fact that they preyed upon the Heartless and stole the hearts they consumed. Lead by Organization XIII, they sought to prey upon the hearts of all. Sora took up his Keyblade again and battled the Darkness, Sealing the Worlds once more and eradicating the Organization's members one by one. When Sora at last faced Xemnas, the High Lord of Organization XIII, he discovered Organization XIII was allied with the Infiltrators, masters of the Heartless. United against the Keybearer, Sora was defeated, leaving Kingdom Hearts without its champion.
Two years thus far have passed since the night of Sora's defeat. And with each passing moment, more of his heroic efforts are undone. Who knows how much longer the World of Kingdom Hearts, and Kingdom Hearts itself, will last? To this day, there is only one question that resides on the mind of those pitiful few who have survived this horrific epidemic of Darkness: "Is there someone, anyone, out there that has the heart to rise up, take Sora's place, and restore Kingdom Hearts to its original glory?"
