Is that not the Beast you said you saw? The one from Hell, the one that strives to drown you in the deepest pits of darkness, the pits of insanity?
My soul is resting yet my body alert; my instincts rule, my mind is shut; I am an animal, a beast on guard, hidden in my cave I cannot sleep, I just watch, watch your every movement, ready to strike at you when you expect it least. Look behind you, my friend, you might see my dead eyes staring through you, and you, too, might put your soul to rest, to be protected from the demon that's stalking you.
