Obviously, Harry would be one of the main characters. He's the one driving the revitalization efforts.
One possible interesting plot point could be Harry introducing new magical spells or techniques that he discovers from ancient texts. This could change the way magic is practiced in the wizarding world.
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.
Obviously, Harry Potter himself would be the main character. He is the one who is escaping the wizarding world.
Well, obviously Harry Potter himself is a main character. He is the center of most of these fanfictions as he takes on the role of the king of the wizarding world.
There could be a young wizard who is just starting to discover his powers. He might be the protagonist and his journey to master magic could be the main plot.
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.
In a fanfic, Hermione might initially be in denial. She would keep expecting Harry to return any day. She would go to their old haunts in Hogwarts, like the library or the Gryffindor common room, and just sit there, reminiscing. As time passes, she realizes she has to move on. She starts teaching at Hogwarts and imparts her knowledge and the values Harry also held dear to the new generation of students.
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.
Well, Harry Potter himself would most likely be one of the main characters. He's the central figure in the original series, so it's reasonable to assume he'd play a big role in the fanfic as well.
