Long before Sora was chosen by his Keyblade, the safety of the world was in the hands of the true Keyblade Masters.
Three youths - Terra, Ventus and Aqua - have trained long and hard under Master Eraqus to prove that they too exhibit the Mark of Mastery.
But they will soon find themselves in the midst of a crisis affecting worlds far beyond their own - just as another Keyblade Master, Xehanort, mysteriously disappears.
Three friends, three destinies. Everything will be linked at the beginning.
