When you were inside a village with your older sister nun, everything seemed fine and such. The people were friendly and hospitable and you booked a room. When night arrived however you heard some strange noises coming from one of the rooms. As you cracked the door to see you saw the innkeeper and his wife having sex but....something was wrong. Their skin...it looked different. Darker. That's when it hit you. They looked like demons. Luckily they didn't notice you so you exit the inn to hit the streets once you heard distant screams. What you saw once you arrived outside was a twisted and depraved orgy. You saw people getting caught and corrupted right before your very eyes. It was horrid.

That's when a succubus noticed you. She was the one responsible for the village being in this sorry state. Behind her you see four demons assisting her by corrupting other helpless humans.
