Another plot could involve a prophecy that states only the one who can balance the power of the two swords can bring peace to the land. The protagonist is chosen to do this but faces many temptations and obstacles along the way, as there are those who want to use the swords for their own evil purposes.
Well, a cool plot could be that one of the thieves is actually working undercover for the police. So, while the two are planning heists together, the undercover thief is secretly trying to gather evidence against the other. But as time goes on, they form a real bond, and the undercover thief has to decide between loyalty to the law and loyalty to their newfound friend. Also, they could be stealing from a corrupt noble. This noble has been oppressing the poor, and the thieves see it as a Robin - Hood - like mission. However, the noble discovers their plan and sets traps for them all over the place.
Another plot idea might be to focus on the lives of the common people in Paris during the revolution in a fanfic of 'A Tale of Two Cities'. Show how they are caught up in the chaos, their hopes, and their fears. For example, create a story about a young peasant who becomes a key figure in the revolution, but then starts to question the extreme violence.
Perhaps a story about a mystery within the abbey walls. For example, an ancient artifact goes missing and the characters have to use their wits and knowledge of the abbey's history to find it. It could involve exploring hidden passages and deciphering old clues. This would give a sense of mystery and intrigue to the fanfiction.
Another plot idea could be a what - if scenario. For example, what if one of the sisters had a different power? This could change the whole dynamic between them and the story. Say, if Elsa had the power to control time instead of ice. It would lead to different challenges and interactions with Anna, like having to deal with the consequences of changing time to save someone, but also the potential chaos it could cause in Arendelle.
One idea could be exploring the backstories of the characters in the 'hill of swords' world. Maybe a character has a hidden past related to a lost civilization in that realm.
One plot idea could be exploring the backstory of the characters in more depth. Maybe show how they became the way they are in the original story. Another idea is to create a different ending, like instead of the traditional happily - ever - after, there could be a bittersweet ending that makes the readers think more. A third plot idea could be to introduce new characters that interact with the existing ones and change the course of the story.
One idea could be a modern Cinderella story where she is a struggling artist instead of a maid. The prince could be a famous art collector who discovers her work at a local gallery. Another could be a Snow White retelling where the seven dwarfs are a group of misfit hackers who protect her from the evil queen's cyber - attacks. And a third could be a Beauty and the Beast story set in a high - tech research facility where the 'beast' is a scientist with a disfiguring accident and 'beauty' is a young intern who helps him regain his confidence and reverse the damage.
One idea could be that the Beast has a secret power that he's been hiding from Belle. Maybe he can communicate with the forest animals in a unique way and they help him in his quest to win Belle's true love. Another could be a backstory for the Enchantress who cursed the Beast, showing her reasons and her own journey. Or perhaps Belle discovers a hidden library in the castle that contains the secrets of breaking the curse not just for the Beast but for the entire enchanted castle and its inhabitants.
One idea could be a story where the dolphin discovers a hidden underwater cave full of ancient treasures. Another could be about the dolphin making an unexpected friendship with a sea turtle. Or perhaps a story where the dolphin uses its unique abilities to save a group of stranded fish.
One idea could be exploring the backstories of the two seers in more depth. Maybe they have a shared past that they are not aware of yet. Another could be putting them in a situation where their seer abilities conflict with each other, leading to a tense and exciting story.
