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.
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.
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.
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.
It could be that in the fanfic, Harry Potter discovers some deep - seated secrets about the wizarding world's power structure. Feeling betrayed, he decides to take extreme actions to expose and destroy it. For example, if he finds out that the Ministry of Magic has been using unethical means to control the wizarding population, he might use his influence and magic to bring it all crashing down. He could start by revealing the truth to the public, which could lead to chaos and the destruction of the established order in the wizarding world.
A 'Harry Potter World Traveler' fanfic can expand the wizarding world in multiple ways. Firstly, it can introduce new magical locations. Instead of just Hogwarts and Diagon Alley, we get to see enchanted cities in South America or hidden islands in the Pacific. Secondly, it can explore different forms of magic. There could be a type of magic based on music in some far - off land. And thirdly, it can bring in new characters from various parts of the world, each with their own backstories and motives.
One interesting storyline could be Harry Potter using unique magic that was not explored in the original series to defeat a new dark wizard threat. Maybe he discovers ancient spells passed down through the Potter family.
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 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.
One possible reason could be extreme anger. If something really bad happened to his loved ones, like if Voldemort came back in a different way and killed all his friends and family this time, Harry might be driven to the edge and decide to destroy the wizarding world that couldn't protect them.
