Intro

The demon followed the girl down the street and into an older home. He watched from the shadows as she began to pull off her coat, giving him a view of scars on her back. He knew these scars, he'd seen similar on several others. This girl wasn't a girl, she was a fallen angel. A holy being who had been stripped of her grace and wings, and then thrown down into the human world. He needed to know why she had been cast out of heaven. He needed to know her.

He slipped into her home and crept up to her room, sticking to the shadows so no one sees him. Once in her room, he locked the door. He took her by surprise and covered her mouth with his hand before she could say anything.

"Sh," He said. "I'm not here to hurt you. I'm here to make you a deal."

He spun the girl around so she was looking at him. She narrowed her eyes.

"I don't make deals with your kind," She spat.

"That hurts, miss," He put a hand over where his heart would be if he had one. "This deal will prevent you from having to adjust to human life and work to keep a home. I just want to know one thing."

"What do you want to know?" She said after a long pause.

"Why did such a pretty angel like you get cast out of paradise?"

"What's your end of this deal?"

"I get you by my side."

There was more silence as the girl thought this over.

"Fine," she said. "I tried to stop someone higher up from doing something I know is wrong. They cast me out before I could gain any ground on my side of the fight."

"What's going on?"

"I'd tell you, but then I'd have to kill you."

The demon smirked a little and his eyes began to glow red.

"I'd like to see you try, my dear," He spun her back around, put a hand over her eyes, and made her fall asleep.
