The screams of the damned had become monotonous, the demon king thought to himself. There once was a time when knowing he had a demon army at his fingertips felt all powerful, and deliciously good. One lift of his long finger, and they did whatever he wanted to whomever he wanted. Hell was the place that he had assisted in ruling well, but now it seemed tedious, and tantamount to boring. The same schemes with the same demons and the same opponents.
The odds of hell conquering Heaven was never the goal. The goal had always been to conquer Earth. Over the centuries, the black book had been his conduit into the world. Through it, he was able to be summoned and through that summoning enjoy his time on Earth. It had been well over 100 years.
