Let me explain, this is the twenty-third century, and is not the glittery, pretty century promised three hundred years ago. Humanity never left Earth to go to the stars, too much selfish behavior.
My name is Sue. My mother is from the Stars, and she taught me.
Everything you have ever been taught about demons is wrong, or at the best fancifully stupid. What fights a Demon is a witch.
What kills a Demon is nothing, banishment is temporary. Know this ball of dirt, Earth, has lost its way, and comes the hour, the day, to its end. The really good news, I am not a witch, but I will not be here in the end, fore I can walk the stars.
Like hell I will run, I was born here, this my home, whether I want it to be or not!
