A powerful and independent witch or wizard like Luna Lovegood's father could potentially help Harry get emancipated. He might have some unorthodox ideas and knowledge about the wizarding laws that could be used to Harry's advantage. Also, some of the more progressive members of the Wizengamot, who are tired of the old - fashioned ways, could side with Harry and help him gain his emancipation. They could see the potential in Harry being an independent force against Voldemort and the corruption in the wizarding world.
In a 'Harry Potter gets emancipated' fanfiction, the plot could involve Harry getting emancipated due to his special status as the Boy Who Lived. With his emancipation, he could take charge of his own finances, which were a mess in the hands of the Dursleys. He could then use his money to fund independent research on dark magic defenses. Maybe he'd even start a small group of like - minded students who are also frustrated with the slow - paced and sometimes - inaccurate teachings at Hogwarts.
Dumbledore could also play a role. Even if he's not alive in the normal sense, his spirit or some form of his magic could guide Harry. He might have known about the connection between Harry and Excalibur all along and left behind some hints or instructions for Harry to follow.
Hermione could help. She's very smart and could research about the dragon's weaknesses.
He might gain more independence in his actions. For example, he could make decisions about his own education and training without the interference of the Ministry or Dumbledore. He could choose to explore magic in his own way, perhaps even study some dark arts to understand his enemies better, but not necessarily use them for evil.
One key aspect could be the re - imagining of Harry Potter's character in a more independent and self - determined way. In fanfiction, the author might explore how Harry breaks free from the traditional constraints of the wizarding world in the original series.
Maybe Hagrid. He has a lot of experience with magical creatures and strange magical phenomena. He could provide Harry with some unique materials or give advice on how to give the golem a proper form and function, like how to make it strong and durable.
The Weasley family could also pitch in. Mr. Weasley might bring some interesting Muggle - like gadgets that he's modified to work with magic. The twins could add some fun elements to the house, like a room with trick stairs or a secret passage that leads to a hidden prank room.
Hermione would be a great helper. She's smart and loves to learn new things. Her knowledge of magic and books could contribute to the building process.
Dumbledore, if he were still alive in the fanfiction, could play a role. He has a vast network of contacts in the wizarding world. He could introduce Harry to a trustworthy real - estate agent, who might be a wizard specializing in properties with magical protections. Also, Dumbledore could use his wisdom to guide Harry in choosing a house that not only meets his current needs but also has the potential to be a safe haven in the future.
Hermione might also help. She would research all about different types of magical chickens and their needs. She could use her knowledge to create a proper schedule for taking care of the chickens and even come up with spells to keep the coop clean.
