... Gosh. So... that's how it happened...

Well... it's alright Aqua. It wasn't your fault, what happened there. It was Xemnas and his apprentices plot that caused all this, not you.

But... back on track again. Sora defeated those who tried to manipulate him, and Riku defeated those who tried to manipulate him... as well as a replica they had created- a lifeform that was given Rikus shape and memories by Naminé, in order to make Sora think Riku was his enemy. A lot of things happened in that castle... but it ended up with Sora, Donald and Goofy having to sleep for a year while Naminé put his memories back in the right order- it was somethin' she had to do in order to heal his mind, makin' him forget all that happened in Castle Oblivion itself. Riku arrived a little bit later, after... after his replica challenged him to a battle to the death: thinking that the only way he could ever have anythin' of his own was to destroy the 'original'. DiZ and Naminé decided to watch over Sora, while I and Riku set out to uncover the Organizations plot.

During that year... Roxas and a friend of his, another replica named Xion, started collectin' hearts for the Organization, not knowing what Xemnas real goal was. Because Roxas and Xion... could both use Keyblades as well.
