What are some interesting plot ideas for Harry Potter post - war fanfiction?

Maybe the apocalypse was caused by a dark magic experiment gone wrong. Now, Harry Potter's friends and family are scattered, and he has to journey across a desolate wizarding world to find them and also figure out how to reverse the damage. Along the way, he discovers new forms of magic that emerged as a result of the chaos.

One idea could be that a dark magic spell has backfired and decimated the wizarding world. Harry and his friends, now much older, have to find a way to restore magic to its former glory. They might search for ancient artifacts that can reverse the damage.

Another plot could focus on individual characters' struggles post - Civil War. Like how Tony Stark tries to make amends with those he fought against while still dealing with his own guilt. Maybe he starts a project to help the victims of the Sokovia incident which was a big part of the rift between the Avengers.

One idea could be about the rebuilding of Hogwarts. The characters could come together to restore the castle to its former glory, dealing with hidden curses left by the Death Eaters during the war. Another could be exploring the relationships that were strained during the war, like Harry and Draco trying to find common ground and forgive past wrongs. And a third idea is focusing on the new generation of witches and wizards, how they are taught about the war and its significance in their magical history classes.

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.

In 'Harry after the war fanfiction', a great plot could be Harry using his fame and influence to start a magical charity. This charity could help those who were affected by the war, like orphans and those who lost their homes. He could also travel around the world to different wizarding communities, sharing his experiences and learning about their unique magical cultures, which would not only be a journey of self - discovery for him but also help in uniting the global wizarding community.

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 Harry Potter using his wizard skills in a boxing ring in a unique way. For example, he might use a levitation charm to dodge punches or use a stunning spell on his opponent's gloves to make them heavier. Another could be a story where the wizarding world has its own boxing league and Harry has to compete against other magical beings like werewolves or giants in the ring.

An enchanter in a fanfiction could create a spell that allows them to communicate with portraits in a way that has never been done before. For example, they could get advice from portraits of long - dead headmasters on how to deal with the current political situation in the wizarding world. Another plot might be that an enchanter is able to enchant the Sorting Hat to sort students based on their future potential rather than their current characteristics. This could lead to some students being placed in houses that they never expected. And finally, an enchanter could be working on a spell to make the Hogwarts Express invisible during its journey, but things go wrong and the train starts to disappear and reappear at random intervals, causing panic among the students.

One idea could be that Amara is a new student at Hogwarts with a special power to communicate with magical creatures in a way no one else can. Harry discovers this and they team up to solve a mystery involving a group of sickly unicorns in the Forbidden Forest.
