Everyone knows that heartless are attracted to the darkness in people's hearts and also to greater sources of darkness, thus, the keyholes. The keyholes in which many worlds have been destroyed and the heartless overrun that world and corrupt it from the
inside out. No one has managed to escape the darkness and regain their memories, only one man as such has managed to do so, and he's the man who is leading the heartless as of now with his powers of darkness. He's called "Ansem", The Seeker of
Darkness, the man with no weakness of the darkness overpowering him. This man has destroyed countless worlds and will continue to do so until his objective is complete. His goal is unknown, but commanders of the Heartless army have been collecting The
Princesses of Heart, to open a keyhole so great, it may hint to Ansem's goal. Even though he controls the shadows of the darkness around him, even a heartless will have a small glimpse of light within it. For this particular light, may be the one, to return to it's
body, and uncover the truth.
-Even in the deepest darkness, a light shines within.
