In addition to Harry, Hermione, and Ron, there could be other characters in this fanfiction. Dumbledore might play a role, even if it's just through his past knowledge or guidance that he left behind. Voldemort could also be a part of the story in some way. Maybe his spirit or his past actions are still influencing the wizarding world and Harry's need to unite the hallows is related to finally putting an end to Voldemort's dark legacy completely.
Well, apart from the obvious ones like Harry, his friends, and his enemies, there could be new characters introduced in this fanfiction. There might be an old wizard or witch who has some hidden knowledge about the Hallows that Harry needs to seek out. Or perhaps a character from a different magical community who has a different perspective on the Hallows and helps Harry in his journey to unite them. It could also be that some minor characters from the original series are given more prominent roles in this fanfiction, like Neville Longbottom who could have some unique contribution to Harry's mission of uniting the hallows.
Well, in the 'Harry Potter unites the hallows' fanfiction, it could be that Harry discovers a deeper meaning behind the Hallows. He might realize that uniting them is not just about physical possession but also about uniting the different aspects of magic they represent. For example, the Elder Wand could symbolize power, the Resurrection Stone could represent life and death, and the Invisibility Cloak could stand for secrecy. By uniting them, Harry could be creating a new balance in the wizarding world.
It could also include some new characters created specifically for the fanfiction. Maybe a young wizard or witch from a minor house who plays a crucial role in uniting Hogwarts. They could have some special abilities or a unique backstory that helps in bringing the students together.
Definitely Harry Potter. He's the face of the franchise and his character is often associated with bringing people together. Then there could be Neville Longbottom. He grew so much throughout the series and could be a great example of how different houses can come together. Luna Lovegood might also be there. Her unique perspective and open - mindedness could help in uniting the houses. And I think we might see Draco Malfoy as well. His character has the potential for redemption and could be part of the story of uniting the houses, showing that even those from Slytherin can be part of the greater good.
Hermione Granger might also be a main character. In the original series, she is an important part of Harry's journey, and in this fanfiction, she could be involved in new storylines, like solving some sort of mystery related to the 'Slutty Hallows' concept.
In many of these fanfictions, Harry is the central figure, but there are also original Hufflepuff characters created by the authors. These characters might be new students who have some special abilities or knowledge. For example, a young Hufflepuff girl who has an uncanny ability to communicate with magical creatures. Harry teams up with her and other Hufflepuff students to explore a part of the Forbidden Forest that has been sealed off for centuries. Their combined skills of Harry's bravery and the Hufflepuffs' unique talents make for an exciting adventure.
Hermione would probably still be a main character. She'd be by Harry's side, trying to help him understand and control the power of the Hallows. She might be researching ancient texts to find out more about any potential side - effects or proper uses of the absorbed Hallows.
Obviously, Harry Potter is one of the main characters as the title implies he is the one who keeps the Deathly Hallows. Hermione Granger and Ron Weasley are likely to be important as well, as they are Harry's closest friends and would probably be involved in whatever adventures or challenges come with Harry having the Hallows.
Harry Potter is of course one of the main characters. Since the Hallows are such an important part of the story, he would be central to any exploration of them. Hermione Granger is also likely to be a main focus as she is always involved in researching and understanding magic. Ron Weasley too, as Harry's best friend, would be there to support and be part of the adventure.
One main theme could be friendship. In the original 'Harry Potter' series, the houses are often divided, but in this fanfiction, Harry might be the catalyst that brings students from different houses together, showing that friendship can transcend house boundaries. Another theme could be unity in the face of a common threat. Maybe there's a new dark force, and the houses have to work as one to defeat it, just like how they did against Voldemort in the books. And perhaps there's a theme of acceptance, where students learn to accept and value the qualities of those from other houses.
In a 'Harry Potter after Deathly Hallows' fanfic, the main characters could include not only the well - known ones but also some minor characters from the original series who now get a chance to shine. Seamus Finnigan, for instance. He could be involved in some sort of magical research that has an impact on the wizarding world. Also, the centaurs could be main characters in a way that shows their relationship with the wizarding community after the war. They could be allies or have some sort of conflict. And of course, Ginny Weasley as a strong and independent witch could be a main character, perhaps leading a Quidditch team or writing for the Daily Prophet about the post - war changes.
