In this fanfiction, perhaps there would be new magical discoveries. Since the battle has shaken up the magical world, new spells or magical artifacts could be unearthed. Also, relationships might change. Ron and Hermione could be planning their wedding and inviting all their friends. And Neville, having proven his bravery during the battle, could take on a teaching role at Hogwarts, passing on his knowledge of herbology to the next generation of students.
In many fanfictions, after the final battle, Harry might focus on rebuilding Hogwarts. He could use his influence to make it a more inclusive and modern place of magic learning, with new courses perhaps on Muggle technology and its integration with magic.
Obviously, Harry Potter himself. He would be a central figure as he was the key in the battle against Voldemort. His friends Ron and Hermione would also be important. They've been with him through thick and thin. Neville Longbottom would be another likely main character. His heroics in the final battle would give him a significant role in the post - battle world. Ginny Weasley too, as Harry's girlfriend and a brave witch in her own right.
πI recommend the following Harry Potter fanfiction to you: Hogwarts Again, HP Doujin: Reversal, Amazing Magic, and HP's Third Prophecy Child. They were both fantasy and modern magic novels, and the plot revolved around the world of Harry Potter, especially after the war. I recommend these doujinshi works because they not only retain the style and characters of the original works, but also add new elements and plots to give readers a deeper understanding of the world of Harry Potter. I hope you like my recommendation.π
Socially, his status as a hero might change. Some might see him as weakened and no longer the invincible hero. This could lead to a shift in the wizarding community's perception of him, and he might have to work hard to regain his former standing.
Obviously, Harry Potter himself would still be a central character. He would be dealing with the aftermath of the battle, like post - traumatic stress or trying to bring about positive changes in the wizarding world.
Well, his life could be full of rebuilding the wizarding world. He might work with Hermione and Ron to establish new laws and regulations that ensure peace and equality. Maybe he'd also travel around the world, spreading the message of unity among wizards from different cultures.
His relationship with Ginny could become even stronger. They might face new challenges together as a couple, like dealing with the post - battle traumas. His friendship with Ron and Hermione could also evolve, as they start new careers and have different responsibilities.
The relationship between the different houses might improve significantly. With the end of Voldemort's reign of terror, the old rivalries between Gryffindor, Slytherin, Hufflepuff and Ravenclaw would start to fade. Students from all houses would work together on projects, share study spaces, and even form inter - house Quidditch teams. There might be more unity among the wizarding community as a whole.
Well, one possibility is that Harry, Ron and Hermione would focus on rebuilding Hogwarts. They might use their magic to restore all the damaged parts of the castle, making it even more magnificent than before. And they could start new magical education programs to ensure that future wizards and witches are well - trained in both magic and ethics.
