Merlin is the greatest and most powerful sorcerer to live. Arthur is the king of Camelot. As you know, Merlin was born to care for Arthur and make sure he becomes the king he was destined to be. After Arthur becomes the king, Merlin becomes a traitor and joins up with the other magic doers, forming a plan against the king and all of Camelot. But... what if it turns out that Merlin was cast under a powerful spell by an evil sorcerer, a practicer of black magic, and before the spell is broken, Merlin does something so bad that will cost him everything. Something so bad that he will never be the same, he will never forgive himself, and the rest of his life will be miserable.
