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.
Dumbledore might also be a main character in this fanfiction. His wisdom and leadership are well - known, and he could be guiding Harry and the others in their efforts to unite Hogwarts. He might offer advice, reveal secrets of the school, or use his powerful magic to encourage unity among the students.
Perhaps in the fanfiction, there is a threat that only a united Hogwarts can face. Harry, along with his friends Hermione and Ron, starts to spread the message of unity. They hold meetings in the Great Hall, inviting students from all houses. Slowly but surely, the students start to cooperate, and they come up with a plan to defeat the threat using their combined knowledge and skills.
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.
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.
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.
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.
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.
Hermione Granger would likely be a main character. She could use her vast knowledge to help Harry in his efforts to fix Hogwarts, whether it's researching ancient spells for repairs or coming up with new educational strategies.
The heir themselves would be a main character, of course. And Harry Potter might still play a role, either as a friend or a rival to the heir. Dumbledore could also be a major character, guiding or observing the heir's journey.
Most likely, the Hogwarts Four would consist of Harry Potter, who is known for his courage and his connection to Voldemort. Hermione Granger, with her vast knowledge of magic and quick thinking. Ron Weasley, who brings loyalty and a sense of humor to the group. And it could be Luna Lovegood as the fourth member. Luna has her own unique perspective on the wizarding world and could add a different flavor to their adventures.
Obviously, Harry Potter is the main character. He is the one taking on the role of the guardian. Hermione and Ron usually play important supporting roles as well. They help Harry in his mission to protect Hogwarts with their knowledge and skills.
