One interesting idea could be new magical creatures or spells that are introduced in the fanfiction. It might expand the magical world in unique ways.
Hermione Granger might also be a main character. In the original series, she is an important part of Harry's journey, and in this fanfiction, she could be involved in new storylines, like solving some sort of mystery related to the 'Slutty Hallows' concept.
One idea could be exploring what would happen if Neville Longbottom was the one who had to face Voldemort in the final battle instead of Harry. Another could be a fanfiction where the Deathly Hallows were discovered in a different order and how that changes the course of the story. Or perhaps a story about the Marauders' era characters influencing the events of the Deathly Hallows from the afterlife.
One interesting idea could be exploring the post - war wizarding world in more detail. For example, how the different houses interact and rebuild Hogwarts. Another idea might be delving into the characters' personal growth. Harry could be seen mentoring young wizards, passing on his knowledge and experiences. And there could also be fanfictions that focus on the relationships that form between characters who were previously on opposite sides during the war, like a Slytherin and a Gryffindor finding common ground.
One idea could be exploring what would happen if Neville found the Deathly Hallows instead of Harry. He has shown great courage throughout the series and it would be fascinating to see how he would handle that power.
One idea could be exploring how the wizarding world rebuilds after the war. Harry, Ron, and Hermione could take on leadership roles in different aspects, like Harry in Auror training reform, Ron in Weasley's Wizard Wheezes expansion to help heal through humor, and Hermione in magical education reform to include more about Muggle - born history. Another could be a story about the next generation at Hogwarts, with Harry's kids and their friends facing new, non - Voldemort - related challenges but still learning from the past.
One interesting plotline could be how Harry's character develops in a different way after absorbing the Hallows. Maybe he becomes more powerful than in the original series and uses this power to reshape the wizarding world. For example, he could use the combined power of the Hallows to end the discrimination between pure - bloods and half - bloods once and for all.
One idea could be exploring the new generation at Hogwarts. Maybe a character discovers a hidden spell that was forgotten during the main series and it has unexpected consequences for the wizarding world. Another could be about the rebuilding of the wizarding community after the war, focusing on how different families reunite and deal with the losses they've suffered.
One interesting plotline could be about the rebuilding of Hogwarts. After all the destruction in the war, seeing how the students, teachers, and even the magical creatures come together to restore the school to its former glory. It could involve new magical discoveries during the reconstruction process.
A plot could revolve around slutty tony's attempt to revive an old - fashioned fashion house. He has to deal with the traditionalists who are against his modern and flamboyant ideas. He uses his unique charm and out - of - the - box thinking to bring new life to the brand, while also facing some personal scandals that threaten to derail his efforts.
One interesting plot idea could be that Harry and Hermione discover a hidden spell within the Deathly Hallows that allows them to time - travel briefly. They use this to go back and change a small but crucial event in the war against Voldemort, which has a big impact on the final outcome. Another could be that they find a secret chamber within the Hallows that holds the lost memories of some of the greatest wizards of all time, and these memories give them the knowledge to defeat Voldemort in a completely unexpected way.
