This story is somewhat based on Beauty and The Beast, and the fanfiction "Bride of Discord" by DisneyFanatic2364.
Once upon a time, there was a kingdom called Biandra that was ruled by King Scourge and his niece, Princess Amy. King Scourge's brother passed in a war, and Amy's mother passed away shortly after Amy's birth. The kingdom of Biandra was a very tranquil, peaceful place... until a mysterious wave of deaths.
Almost every night, a villager died. The deceased corpse would have strange bite marks on their wrist or neck. King Scourge decided to get more security for his kingdom. He hired more guards for inside the castle and to protect the villagers on the streets of Biandra.
King Scourge also decided to have Amy engaged to Prince Manic of Zaegan. Princess Amy thoroughly refused, but to no avail. She knew her uncle was only trying to protect her, but she didn't want to marry a complete stranger. No matter what she was told about him, she couldn't find a single thing to like, let alone love, about him.
One day, King Scourge was sitting in his throne room when a messenger came in. "Your Highness! You have visitors." he informed. The king nodded and the messenger left to get the visitors.
Meanwhile, Amy was in her room with her maids, Blaze, Rouge, and Cream. Cream was brushing Amy's hair while Rouge was fitting her for her wedding dress. Blaze was checking things off a list for the wedding, which would take place within two weeks. Amy sighed sadly. "Maybe Uncle will change his mind." she wondered. Cream shook her head. "The king really wants to make sure you are safe, Princess Amy." she said. Rouge pulled a mirror over for Amy to see the dress. "There. How does that look?" she asked. Amy's eyes started to water. "I... I want to think it's beautiful... but, it can't be. Not if I have to wear it when I marry Prince Manic. I don't love him." she said, crying. Blaze put her list down and went over to Amy. "I'm sorry, Princess Amy... but, there's nothing we can do." Amy cried into her hands as she heard this.
King Scourge looked at the gentleman before him. He was a red and black hedgehog. His clothes were somewhat tattered, but still had royal appeal. "State your business here." Scourge said. The hedgehog nodded. "First, let me introduce myself. My name is Shadow. Now, I have heard about all the deaths in your kingdom." Shadow said, getting the king's attention. "Go on." he urged. Shadow smirked. "You might be interested in the fact that I know who did it." he said. King Scourge stood up. "Who?!" he asked. Shadow crossed his arms. "You're looking at him."
