Another plotline could be that Harry, in his teaching role, discovers a new and powerful form of defensive magic. He then has to decide whether to share it with the entire wizarding world or keep it within Hogwarts for the safety of his students. This could lead to a conflict with the Ministry of Magic, who may want to use the magic for their own purposes. Also, some students might be jealous of the attention Harry gives to certain students who show great potential in this new form of magic.
Obviously, Harry Potter is the main character as he is the one doing the teaching. His students would also be important characters. This could include well - known characters like Neville Longbottom, who might struggle at first but then thrive under Harry's teaching. Ginny Weasley could also be a prominent student in the class, showing great skill and courage.
One possible plotline could be Harry finding some ancient potions book in the library that has unique brewing methods. He then secretly practices them in an abandoned classroom.
One interesting plotline is when Lily is given the chance to change the future. In some fanfictions, she has the power to go back in time and make different choices, like whether to marry James or not. Another is when she discovers hidden magic within herself that no one else knew about. This often leads to her having to face new challenges and enemies.
One interesting plotline could be Snape finally seeing Harry's potential in potions and secretly mentoring him outside of class. This could lead to a grudging respect between them.
One interesting aspect could be how Harry Potter might use his own unique experiences in the wizarding world to shape the fanfiction he writes. For example, he could write about his adventures with Hermione and Ron in a more creative and detailed way, adding elements that were left out in the original books.
One interesting plotline could be about the Founders' initial meetings and how they decided to build Hogwarts. Maybe they had different ideas at first but then came to a consensus on the school's values and layout.
Well, perhaps in this fanfiction, the Phoenix plays a role in revealing hidden secrets about Harry's family. It could lead Harry to discover an ancient magic that was long forgotten by the wizarding world, which was somehow related to his family. This could then set him on a new quest, different from the one in the original books, and change the course of the story completely.
A common plotline is the characters' post - graduation plans. Some fanfictions might explore how Harry, Hermione, and Ron decide on their career paths. Maybe Harry is conflicted between becoming an Auror or a teacher at Hogwarts. Hermione could be considering further studies in ancient magic, and Ron might be thinking about joining his brothers in the joke shop business. This exploration of their future dreams and how they support each other during this transition period can be really engaging.
A possible plotline could be a time - travel fanfiction where Harry and his friends accidentally travel back in time to the era when the founders of Hogwarts were alive. They get to interact with the founders, learn about the early days of Hogwarts, and face challenges that come with changing the past or ensuring that history unfolds as it should. This would involve dealing with the different magical cultures and practices of that time, as well as the complex personalities of the founders.
One interesting plotline could be the brothers having a secret mission within Hogwarts that the original books didn't cover. For example, they might be on a quest to find a hidden magical artifact that has been lost for centuries. Another could be their relationship dynamic affecting the course of major events in the wizarding world, like how they interact with Harry and his friends during the Triwizard Tournament.
