Well, in this fanfic, perhaps Harry discovers some ancient magic that makes him the rightful king of the wizarding world. He might have to face a lot of opposition from the old wizarding families who are used to having power. So, it could be a story of him fighting for his throne and also trying to bring equality among all wizards and witches. He could use his new position to improve the relations between different magical creatures as well.
It could be about Harry Potter achieving ultimate power and ruling the wizarding world. Maybe he overcomes new and even more dangerous dark forces and in the process, he becomes the king. He could make new laws and bring about great changes to Hogwarts and the entire wizarding community.
One possible reason could be the trauma he has faced. Harry has endured a great deal of pain, from the loss of his parents to the constant battles and threats in the wizarding world. He might want to escape all that and find peace away from it.
One possible reason could be that he's tired of the constant danger and politics in the wizarding world. After all he's been through so much. He might just want a normal, quiet life away from magic.
Obviously, Harry Potter himself. Hermione and Ron would most likely be there too, as his closest friends. Dumbledore might still play a role, perhaps as an advisor to Harry in his new position. And there could be new characters, like wizards and witches from other parts of the world who come to see the new king.
If Harry Potter becomes king in fanfiction, the wizarding world would likely see a major shift in power dynamics. For one, Hogwarts might become more directly involved in ruling, with Harry perhaps implementing new educational reforms. He could also change the way pure - bloods, half - bloods, and Muggle - borns interact, promoting more equality. His past experiences with Voldemort would make him a strong advocate for unity among all wizards and witches. And his friends, like Hermione and Ron, would probably be his closest advisors, bringing in their own unique perspectives to help him rule.
One possible reason could be that in some fanfics, the author wants to explore a different side of Harry. Maybe he's tired of the constant chaos and danger in the wizarding world. Another reason might be to show his independence from the typical wizarding narrative. He could be seeking a more normal life away from all the magic and politics.
The wizarding world would have a complex reaction. On one hand, many would support Harry as they believe he can bring positive change. On the other hand, there would be political factions within the wizarding world. Some might try to use Harry's new position for their own gain, while others would be cautious and want to maintain the status quo. Harry would have to navigate these different reactions and interests to ensure the stability of both the wizarding and non - wizarding parts of England.
The plot could start with Harry making a firm decision to leave. He might go into hiding in the Muggle world, changing his appearance and identity. Then, the wizarding world would gradually realize his absence and start to search for him, which could lead to a cat - and - mouse chase.
It could also be a story where Harry has lost all hope. He has seen too much death and destruction in the wizarding world, from the war with Voldemort. He might think that the only way to end all the pain and suffering is to just end the wizarding world as it is. He could start by attacking the key institutions like Hogwarts and the Ministry of Magic.
Perhaps he leaves in search of a more peaceful life. The wizarding world, despite its magic, has been filled with turmoil for him. He could be seeking a place where he can simply be Harry, not 'The Boy Who Lived' or the hero who defeated Voldemort. He may also be on a quest to discover more about his family's past in the Muggle world, something that has been somewhat overlooked in his life in the wizarding world.
One reason could be that he's tired of the constant danger and battles. After all he's been through, he might just want a normal, peaceful life away from magic. Maybe he wants to start a family in the Muggle world where his kids can grow up without the threat of dark wizards.
