Note: This story is just a theory. So if you disagree with this, don't start cussing me out.
*Part 1: The Beginning*
In the beginning, there were 4 Chasers. Each Chaser created their own Keyblade. The Keyblade had the power to create, destroy, or rewrite(edit). For a few years there was peace. Then the Chasers began to separate. 2 Chasers journeyed toward the power of light. The other 2 Chasers journeyed toward the power of darkness. The War of the Keyblades began. Then one of the Dark Chasers regretted joining the darkness. He was forgiven and began his journey toward the power of light(just like Riku). The other Dark Chaser, Xehanort, rose up his dark army and warred against the Chasers of Light. The 3 Chasers of light destroyed Xehanort. As consequences for his defeat, Xehanort's memories were wiped out when he was reborn again in Radiant Garden and taken under Ansem's wing.
