Much of my life has been dedicated to 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.
