Hey Jonboy, thanks for dropping by! I will say this: He is a devil, but he's not the "head" devil. He's just an underling devil, but even they can make a big mess!
This particular devil exists in the form of a man that is still alive on planet earth. There are some clues in the story that can definitely identify him if you feel like doing some sleuthing. :)
Oh so this was written as a type of riddle for the reader to figure out who the man is, that is very clever sir free-reign!
