Editing Lost Master Arc

Following the defeat of Master [[Xehanort]] and the [[real Organization XIII]], [[Sora]] resolves to find the heart of [[Kairi]], who was struck down by Xehanort in order to forge the [[χ-blade]] moments before the final battle. Despite misgivings from King Mickey, since Sora previously failed his Mark of Mastery exam, Sora successfully manages to locate and restore Kairi, though his own heart is lost in the process and he fades away. Sora's friends later try various methods to locate him, but all are unsuccessful until the [[Fairy Godmother]] intervenes and suggests that they use the dreams of Kairi and a [[Nameless Star]]. Kairi is confronted in her dreams by an illusion of Xehanort, who mentions a world "on the other side", which the Nameless Star goes on to identify as a world named [[Quadratum]]. Using the power of waking, Riku opens a portal to Quadratum to search for Sora. Meanwhile, in Quadratum, Sora is accosted by a young man named [[Yozora]], who claims to be sent there on a mission to save Sora. Yozora is narrowly defeated, and concludes Sora does not need him yet before fading away. Still stuck in this unfamiliar world, Sora presses on to find answers.
