Note: I have also long since come to the conclusion that the entire book is out for your soul and won’t stop until it eats a good portion of it. Perhaps that’s why it’s so dang horrid when you get rejected.
And… back to the subject.
Antagonists. The Bad Guy. The Darth Vader of your story. (LAWYERS. Don’t eat me, please! I DO NOT OWN Darth Vader. I am not claiming that I do! ) The reason your protagonist is in pain. The reason your protagonist had to leave his happy life of coffee and donuts (yes, I know, I’m making wild assumptions here) to go out into reality.
