One interesting plot point could be an alternate take on their relationship during the Horcrux hunt. Maybe in the fanfic, they face a particularly difficult Horcrux that tests their bond in a new way, like a Horcrux that plays on their insecurities about each other.
A lot of fanfictions focus on Ron and Hermione's post - Deathly Hallows life. For example, how they adjust to normal life after all the chaos. They might struggle with things like Ron trying to find a proper job in the wizarding world and Hermione helping him. Their relationship might also face some new challenges, like dealing with family expectations, which makes for an interesting read.
In many fanfics, their relationship develops through shared hardships during the search for Horcruxes. They rely on each other more and more, which deepens their emotional connection.
One great fanfic could be 'The Life After' which shows Ron and Hermione dealing with the post - war wizarding world. They face challenges like rebuilding Hogwarts and starting their own family in this fic.
Another plotline might involve Hermione being transported back in time to the era when the Deathly Hallows were first created. There, she has to navigate the complex politics and magic of that time to ensure the Hallows are used in a way that doesn't lead to chaos in the future. She could meet the original creators and influence their decisions.
One interesting fanfiction could be one where Harry and Hermione go on a side quest during the search for Horcruxes. In this story, they might encounter a long - lost magical creature that holds a key to understanding the Deathly Hallows better. It could add a whole new layer of adventure to their journey.
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.
Maybe in the fanfiction, the Deathly Hallows have a connection to an ancient prophecy that only Harry and Hermione can decipher. This prophecy reveals a way to bring true and lasting peace to the wizarding world. So they have to race against time, with the Death Eaters hot on their trail, to figure out the meaning and fulfill the prophecy.
One common theme is family. Since they are likely to start a family after the war, many fanfics explore how they raise their children and pass on their values. For example, teaching their kids about the importance of friendship and courage, just like they learned during their own adventures.
One possibility is that they continue to work in the Ministry of Magic. Hermione might be in a high - ranking position in the Department of Magical Law Enforcement, using her intelligence to reform wizarding laws. Ron could be part of the Auror department, helping to keep the wizarding world safe. They would come home to their cozy house in the evenings and share stories about their day with their kids, who would be growing up with a great love for magic.
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.
