Encounter of the dark one

"I own you," the creatures voice came out without even the slightest movement of his mouth, its voice deep and only whispered out. I stared calmly back into its eyes, knowing full well its teeth could tear my flesh from bone if it dared desire. "I am a part of you," It continued, "I always have been, lurking inside you, lurking inside all the souls of man, every empty crevice where the light has not pierced, every shadow, I am there. I always have been, and I always will be."
