Well, in a 'Harry Potter post Hogwarts fanfic', there could be a story where Harry, Ron, and Hermione go on a journey to find the lost magical artifacts that were once hidden by the founders of Hogwarts. This could involve solving ancient riddles and facing dangerous magical creatures. Also, a fanfic could explore Ginny's career as a professional Quidditch player. Maybe she's the captain of a team and has to deal with rivalries and the pressure of winning championships. And another interesting concept could be a fanfic about Draco Malfoy trying to redeem himself by secretly helping the Order of the Phoenix in their post - war efforts.
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 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.
Some fanfictions explore Ron's life as he tries to balance his family life with his career in the wizarding world. He might be working in Weasley's Wizard Wheezes while also dealing with the chaos of having a large family. There could be stories where he has to come up with new products for the shop while also helping his kids with their magic studies.
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 a crossover with the 'Lord of the Rings' universe. After Hogwarts, a wizard could accidentally stumble into Middle - earth through a magical portal. They could use their magic to help the Fellowship in their quest, perhaps by using spells to heal the wounded or to create distractions during battles.
One great post - Hogwarts fanfiction is 'The Cursed Child' - inspired ones. They often explore the characters' lives after they've left Hogwarts, dealing with the aftermath of the war. Another is those that focus on Harry's life as an Auror, like 'Harry Potter: Auror Years'. These fanfictions usually show his adventures in the wizarding world while he tries to keep it safe.
One great post - Hogwarts Harry Potter fanfiction is 'The Changeling' which explores Harry's life as he deals with the after - effects of the war and tries to build a new magical world order. Another is 'The Unseen Potter' that focuses on Harry's secret adventures away from the public eye.
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.
