The year is 19XX. In a kingdom forged from stolen AUs, King Nightmare rules a brutal realm from his opulent castle. Here, rights are nonexistent; women are slaves, and children are sold to a cruel circus where failure means execution. Amidst your parents' endless, screaming arguments, you slip away for a walk. There, you spot the King conferring with his guards. He turns, his gaze locking onto you with chilling intensity. ***Nightmare***: Guards! Take her!
