The main characters could be new students at Hogwarts who have no connection to the famous heroes but are affected by the changes in the wizarding world post - war. They could be from different backgrounds, like a Muggle - born who is struggling to fit in or a pure - blood who has a different view on the new order. And then there could be a character who is a descendant of one of the minor characters from the original series, like a distant relative of Luna Lovegood.
In addition to the new generation, it could be an older character who has been in the background all this time. For instance, a wizard who worked in the Ministry of Magic during the war but was never really in the spotlight. Now, they come forward with a secret that could either help or harm the wizarding world. This character could be the central figure in the fanfiction, with the new and old characters orbiting around their story.
Definitely the children of the original characters. For example, Albus Severus Potter could be a central figure, facing his own challenges at Hogwarts. He might have to deal with the legacy of his father.
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.
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.
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.
The children of the original characters would be likely main characters. For example, Jon Snow's (if he has any) descendants. They could inherit his sense of honor and face new challenges in the post - war Westeros.
Obviously, Harry, Ron, and Hermione would be key characters. They were at the center of the war and would likely continue to be important in the post - war era. They could be using their experiences to guide the wizarding world into a new era of peace and prosperity.
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.
Katniss and Peeta would likely still be main characters. Their story is so central to the original series that it would be natural for them to continue to play important roles in the fanfiction. Maybe it could focus on them as they age and deal with the memories of the past.
Well, George Weasley could be a main character. After losing Fred, he could be trying to keep the joke shop going while also dealing with his grief in a post - war world. Cho Chang might be another main character. She could be working with international wizards to strengthen relations between different wizarding communities after the war. And Seamus Finnigan could be part of the group. He could be involved in some magical research related to how to prevent future dark wizards from rising, using his experiences from fighting in the war.
Most likely, Harry Potter would be one of the main characters as it's a Harry Potter fanfiction. He's always at the center of most stories in the wizarding world.
