The Animus Apocrypha

[Laemor]

"Where did it all begin... Oh... I remember now."
          

Humanities fragility is exceptionally precious under times of intense exposure to despair... It was this thought, this nightmare... That gave birth to I. Irkalla... I was without shape, without meaning. Lost, yet never found. Hiding away in the shadows of man. Blending in as though I was, but natural to their existence. From person-to-person, I went. In search of a meaning behind it all, but to no avail. I found, nothing, but the sight of what could become of humanity. Should they excel, should they fail... With these memories, I take with me... Mans mistake, their accomplishments. To mold a future, inescapable to the ignorant. All shall learn, all shall realize. 

I can only live where there is light, but if I die... It'll be from the light shining on me...
What am I?
