In a fanfic about Harry leaving Hogwarts, he could leave to become an Auror trainer in a different country. He'd take all the skills he learned from his Defense Against the Dark Arts classes and pass them on. He might also leave because he wants to research a new form of magic that Hogwarts doesn't teach. This could involve traveling to far - flung places and meeting with reclusive wizards. Additionally, he could leave to help a friend who has gotten into trouble outside of Hogwarts, and in the process, discovers a whole new side of the wizarding world he never knew existed.
One idea could be Harry leaving Hogwarts to hunt down remaining Death Eaters who escaped justice. He could travel the wizarding world, using his skills and knowledge from Hogwarts to outwit them. Another could be that he leaves to start a new school for magically - gifted orphans, based on his own experiences. Or perhaps he leaves to explore ancient magic that was forbidden at Hogwarts.
One idea could be exploring a character's backstory that wasn't fully covered in the game. For example, delving deeper into the family history of a side character. Maybe they have a hidden connection to one of the main wizarding families. Another plot could involve a new mystery within Hogwarts, like a secret chamber that has been long forgotten but holds a powerful magical artifact. A third idea would be to create an alternate timeline where a major event in the game didn't happen, and see how it changes the relationships and the overall story at Hogwarts.
One idea could be about Harry starting his own school of magic. He could combine the best of Hogwarts with new and innovative ways of teaching magic, like including Muggle technology in some lessons. Another idea is a fanfic focusing on Hermione's work in the Ministry of Magic, perhaps she's in charge of reforming some archaic laws regarding house - elves. A third idea might be a story about Ron and Neville opening a magical joke shop together, filled with all kinds of hilarious and magical prank items.
One interesting plot could be a story where the Hogwarts staff has to deal with a new, mysterious dark magic that is affecting the students' minds. They have to work together, using their different areas of expertise. For example, Professor McGonagall might use her Transfiguration skills to create barriers, while Snape uses his Potions knowledge to create antidotes. Another plot could be a time - travel story where the staff goes back in time to prevent a major disaster at Hogwarts that was previously unknown. And a third could be a story about the staff's relationships outside of Hogwarts, like how Hagrid might have a secret friendship with a giant community that impacts his role at the school.
One idea could be a story about a new student who discovers a long - forgotten magic spell in the Hogwarts library that has the power to change the appearance of the entire school. Another could be a fanfiction where the characters have to deal with a strange magical illness that only affects those with a certain type of magic bloodline.
Well, perhaps in the fanfiction, Harry returns to Hogwarts to find a long - lost magical artifact hidden deep within the castle. As he searches, he uncovers secrets about the founders of Hogwarts that were long forgotten. He might also team up with old friends and new students to solve the mystery. It could involve facing off against a new dark wizard who is also after the artifact.
A great plot could be that Harry decides to open Hogwarts to students from all over the world in a more inclusive way. However, this causes some cultural clashes among the students and staff. He has to find a way to make everyone feel welcome and at the same time maintain the school's traditions. Also, there could be a plot where a mysterious prophecy about Hogwarts is revealed, and Harry as headmaster has to figure out how to prevent its doom.
Well, a cool plot in 'Harry Potter Hogwarts Heir Fanfiction' could be that the heir is actually a character we least expect, like a Muggle - born. This would challenge the traditional ideas about pure - blood and half - blood supremacy in the wizarding world. They could use their unique perspective as an heir to bring about changes in Hogwarts' curriculum and social structure. For example, they might introduce new forms of magic that are more inclusive of different backgrounds.
One idea could be a story where the main character discovers a hidden chamber in Hogwarts that has been lost for centuries. It could be filled with ancient magic and dangerous creatures. Another plot could involve a time - traveling adventure, where the character goes back in time to witness a significant event in Hogwarts' history. Maybe they have to stop a dark wizard from changing the past. A third idea is a story centered around a mysterious new student who has a special power that no one understands, and the main character has to figure out if they are a friend or a foe.
One idea could be that the Hogwarts Guardians are a secret group within the school that protects a hidden magical artifact. They have to face off against a group of dark wizards who are also after it.
One idea could be that Harry discovers a hidden chamber in Hogwarts that was unknown even to Dumbledore. This chamber could hold secrets about the founders that have been lost over time. Another could be that the students return to find Hogwarts has been taken over by a new dark force that's not related to Voldemort but has its own set of dark magic. Maybe a group of former Death Eaters who escaped justice are trying to create a new regime within the school walls.
