Angels are everywhere. They are under the everyday world, behind it, beyond it. They are sent by the God-Machine to enact its will through time and space, delivering messages, building infrastructure, protecting some people, killing others. And you were one of those angels…
But not anymore.
In Demon: The Descent, you play one of the fallen agents of the God-Machine, a former angel who defected to the human race. Now you are Unchained, and search for a place that you can be free, all the while avoiding the notice of the still-loyal agents. You cannot go back to the shining, sterile Heaven.
All you can do is reign in Hell.
