The world is sick and dying. The politicians, CEO's, and world leaders are more concerned with dodging the public eye than improving the world in the slightest. Activists pushing for a new world are murdered by hate groups or dirty cops, and the legal system is less a way to determine right and wrong than powerful and weak.
Monsters hunt in the dark, and trying to fight is a death sentence. They are stronger than you, faster than you, and they own the world around you so thoroughly that you'd be called a madman for trying to find them. This is their playground, and you are their toys.
Or at least, you were.
You saw something that was supposed to be kept a secret. Maybe it was on accident, or maybe you were invited into a secret order, or maybe someone thought they could have some fun turning the rest of your life into a very short hell. Then? The details are different for everyone, but you all walked away unstoppable, and now you've got a choice.
With all this power, and with this new terrible world laid out in front of you, what will you do to it?
