Some fanfics might focus on the idea of time - travel within the 'harry potter' universe in the context of the epilogue. Imagine if one of the next - generation characters accidentally travels back in time and meets the younger versions of their parents. This could lead to all sorts of comical and heart - warming moments. It could also explore how this time - travel affects the future and whether they are able to return to their own time without causing any major disruptions to the timeline.
In many 'harry potter epilogue fanfic', aside from the kids, the original characters like Harry, Hermione, and Ron also make appearances. They are shown as mentors or just as parents in the background. Sometimes, Draco Malfoy might also be included, either as an old acquaintance or as someone who has changed and is now more involved in the new generation's lives. His son Scorpius could be a key character too, interacting with the Potter and Weasley kids.
One benefit is getting more character development. Fanfiction often delves deeper into the characters' post - Hogwarts lives. For example, it might explore how Harry copes with his fame in a more detailed way than the original epilogue. Another advantage is exploring different storylines. Maybe in fanfiction, we can see alternate relationships or adventures that the official epilogue didn't touch on.
There might also be other characters from the original series making appearances. For example, Neville could show up as a respected Herbology teacher at Hogwarts. His character development from a shy boy to a brave hero could be referenced, and he could interact with Harry and Hermione in the context of the fanfic, perhaps helping them with some plant - related magic or knowledge in their adventures.
One possibility could be that Harry and Hermione start a magical research project together. They explore some long - forgotten spells and their implications in the wizarding world. Maybe they discover a new way to use magic that could change the way magic is taught at Hogwarts.
Often, a sense of nostalgia is a theme. Since it's set after the main story, it can bring back memories of the original Harry Potter journey. Fanfictions in this area might also focus on the healing process of the characters from the traumas they endured during the fight against Voldemort. It gives the author a chance to show how they've moved on and are building a better future. Additionally, there can be themes related to the power of love and friendship, just as in the original books, but now in a new context of their adult lives.
In the 'Harry Potter after the epilogue fanfiction', perhaps there are changes in the Hogwarts curriculum. They might introduce new magical subjects that were previously undiscovered. Also, the relationships between the different houses could evolve. For example, Slytherin and Gryffindor could form an unexpected alliance to deal with a common problem in the wizarding world.
In an 'Epilogue Harry Potter fanfiction', you might consider a story where Harry Potter discovers a long - hidden secret about Hogwarts that was overlooked during his time as a student. This could lead to a new adventure with his friends. You could also explore the idea of the magical creatures in the wizarding world becoming more involved in the human - wizard relations. For instance, the centaurs sharing their ancient wisdom with the wizards. Additionally, a fanfiction could be centered around the Muggle - born wizards and witches helping to bridge the gap between the Muggle and wizarding worlds even more.
Lily Luna Potter is also a favorite. She's a bit of an enigma in the original epilogue, so fanfiction gives writers the chance to really flesh out her character. She could be portrayed as a strong - willed and independent witch, with her own set of adventures at Hogwarts. And of course, Teddy Lupin is popular too. He has a unique backstory, being the son of Remus Lupin and Nymphadora Tonks, and his role in the post - Voldemort wizarding world can be explored in many ways.
One interesting idea could be exploring the further adventures of the next generation at Hogwarts. Maybe they discover a long - lost magic that was forgotten. Another idea might be delving deeper into the relationships that were just hinted at in the original epilogue, like how Albus Severus Potter really gets along with his Slytherin friends.
