What are some interesting plot ideas in 'Harry Potter Worlds End Fanfiction'?

A great plot for a Potter Manor fanfiction could involve a mystery that surrounds the manor. For instance, strange noises at night lead Harry to uncover a long - forgotten chamber. It could also be about Harry restoring the manor to its former glory, perhaps with the help of Hermione's research on ancient magic used in the construction of such manors.

One interesting plot idea could be exploring what would happen if Harry had a different upbringing, like being raised by the Malfoys. It would completely change his view of the wizarding world and his relationships. Another idea might be a time - travel fanfic where Harry goes back to the Marauders' era and interacts with his parents and their friends. This could lead to him preventing certain tragedies or changing the future in unexpected ways. And then there's the concept of a fanfic where the roles are reversed, and Voldemort is the one trying to protect the wizarding world from a greater evil, with Harry being the main antagonist.

One idea could be an accountant at Gringotts who discovers a financial conspiracy within the wizarding world. Maybe they find that certain dark wizards are using illegal accounting spells to siphon off gold from vaults.

Another idea could be that the pretender is an impostor who has infiltrated Hogwarts with an ulterior motive. Maybe they are working for a dark wizard and are trying to steal powerful magical artifacts from the school. This would create a lot of tension and mystery as the characters try to figure out who the pretender really is and what their plans are.

Another plot might involve a time - travel aspect within the fanfiction chains. A character could go back in time to change a small event, like preventing a certain spell from being misused, which then has a ripple effect on the entire wizarding world, creating a whole new set of adventures for Harry and his friends.

Perhaps a revenant of a Death Eater returns, not to cause more harm, but to seek redemption. This Death Eater revenant could be haunted by the atrocities they committed during the war. They might try to secretly help the students of Hogwarts by warning them of dark magic remnants hidden in the Forbidden Forest or old abandoned classrooms.

Another plot could involve the Huntsman being mistaken for a dark wizard by the Ministry of Magic. Harry and his friends would then have to figure out the truth and help the Huntsman prove his innocence. This could lead to a lot of action and mystery within Hogwarts and the wizarding community at large.

One idea could be to have a tournament where the participants are not just students from Hogwarts, but from all over the wizarding world. This could introduce new characters and magical abilities. Another could be a tournament with a twist, like the tasks are based on solving ancient wizarding mysteries instead of the typical challenges.

One interesting plot idea could be a crossover where characters from 'Harry Potter' and 'The Originals' have to team up to fight a common dark magic threat. For example, Harry Potter and Klaus Mikaelson might initially be at odds due to their different views on magic use and power, but they realize they need each other's skills to defeat a powerful ancient evil that is threatening both the wizarding world and the vampire - werewolf - witch community in 'The Originals'.

One idea could be Demetri getting caught in the middle of a Hogwarts mystery. Maybe he's sent on a mission by the Death Eaters that somehow intersects with Harry's search for a Horcrux. Another could be a story where Demetri has a change of heart and decides to help Harry, seeing the error of Voldemort's ways.
