Death has been personified in many ways throughout history; a dark, shadowy hooded figure with skeletal hands, the Devil, demons, even angels... angels... just the thought of it makes me want to laugh! We are far different from any of those beings.
We can understand why you humans would believe such foolish things, though. You see, we used to be like you; slow, weak, oblivious to the world that is right in front of you.
You give us many names; monsters, murderers, minions of the devil, and even angels of death. No, we are just like you. Physically, that is. And we are everywhere. In fact, if you are reading this right now, there is a good chance one of us just passed you by. Watching you. Making sure you don't see this. Oh, you poor unfortunate humans, not seeing the world as it truly is. We are the managers of life and death. We are the reapers.
