Kingdom Hearts: Ansem's Report 1

Much of my life has been dedicated to the pursuit of knowledge.
That knowledge has guarded this world well. Not a soul doubts that.
I am blessed with people's smiles and respect. But though I am called a sage, there are things I do not understand.
I believe darkness sleeps in every heart, no matter how pure. Given the chance, the smallest drop can spread and swallow the heart. I have witnessed it many times.
Darkness...Darkness of the heart. How is it born?
How does it come to affect us so?
As ruler of this world, I must find the answers. I must find them before the world is lost to those taken by the darkness.
