“Long ago in a distant land, I Xehanort, the Keyblade Master of darkness, sparked an unspeakable war! But a foolish island boy, wielding a keyblade of his own, stepped forth to oppose me. Before the final blow was struck my younger self threw open a portal in time and flung him into the future, where Kingdom Hearts is mine! Now the fool seeks to return to the past and undo the future that is Xehanort!”
