What are some interesting plotlines in 'Harry Potter after the books fanfiction'?

Another plotline could focus on the next generation at Hogwarts. Maybe there are new challenges and mysteries for the children of Harry, Ron, and Hermione. They could be dealing with a new dark force that is emerging, and they have to use their parents' teachings and their own wits to combat it. There could also be a story about how the relationships between different houses at Hogwarts have evolved over the years, and how they now have to work together more than ever.

One possible interesting plotline could be the characters dealing with the after - effects of a boggart encounter on a larger scale. Maybe they start to have nightmares about it and have to find ways to overcome their new - found fears. For example, Harry might have to deal with his fear of Voldemort resurfacing in his dreams due to the boggart incident.

In this type of fanfiction, a great plotline could be the exploration of the characters' post - war traumas through their relationships in the harem. Harry, for instance, might have nightmares about the war. His 'harem' of friends and potential love interests could be there to comfort him. Hermione could use her intelligence to help him analyze his feelings, Ginny could be the one to bring out his more carefree side, and other characters could contribute in their own ways. This way, the harem setting becomes a means of healing and growth for all the characters involved.

One interesting plotline could be about the rebuilding of Hogwarts. The war has left it in ruins, and the characters have to come together to restore it to its former glory. They might face challenges like finding the right magical materials and dealing with the memories of the battles that took place there.

Well, some might involve magical creatures with furry characteristics in new adventures at Hogwarts. For example, a werewolf character could have a unique story arc that intersects with the main Harry Potter plot. Maybe they are trying to find a cure or dealing with the prejudice within the wizarding world in a different way than what's in the original books.

One possible plotline could be a comical take on baby Harry's magical mishaps. Maybe he accidentally makes his diapers levitate or turns his crib into a mini Hogwarts. Another could be about how the other characters like Hagrid or Dumbledore interact with baby Harry in this unique situation, perhaps trying to figure out how to handle his early magical outbursts while he's still in diapers.

Perhaps a plotline where the ogre has some sort of special power that the wizards in Harry Potter are interested in. This could lead to a whole series of events where they try to either control or cooperate with the ogre.

In some fanfiction, a familiar might get lost in a different dimension. So, the main character has to go on a journey to find it. Along the way, they meet strange new creatures and learn new spells, which is really exciting. It also shows a different side of the bond between a wizard and their familiar.

There could also be a fanfiction where a member of the Sacred 28 discovers a long - lost family secret that has the potential to change the power dynamics among the pure - blood families. This secret could be related to a hidden magic or a forgotten alliance, and as they try to uncover more about it, they face opposition from other families who fear the change it might bring.

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.
