A great plotline could be Harry's attempts to improve the education system in the wizarding world through the Ministry. He might introduce new courses at Hogwarts based on his own knowledge gaps during his time as a student. He could also work on making magic more accessible to those from non - magical backgrounds who have discovered their magical abilities later in life, which would surely face opposition from some traditionalist wizards at the Ministry.
One interesting plotline could be Harry using his unique experiences as a student at Hogwarts to reform the Ministry. For example, he might create more fair laws regarding magical creatures, having befriended so many during his school days. Another could be his struggle with the pure - blood supremacist factions within the Ministry, trying to change the old - fashioned views that have long been ingrained there.
Well, a great plotline could be Hermione dealing with dark wizard threats that have emerged under her tenure. She would use her intelligence and knowledge of magic to outwit the villains. Also, there could be a sub - plot about her relationship with her former classmates. Maybe Harry and Ron play important roles in her administration, like being advisors or leading special magical tasks.
One interesting plotline could be the discovery of a new kind of magic that the heir of magic possesses. This new magic might be a blend of different existing magics in the Harry Potter universe, allowing for unique spells and abilities.
One interesting plotline could be the discovery of a new, hidden magical ability that the heir of magic possesses. This ability might be something that even Voldemort didn't know about and could turn the tide in battles against dark forces. Another could be the exploration of the heir's family history, uncovering secrets that have been long buried in the wizarding world. For example, they might find out that their family had a connection to an ancient and powerful magical artifact that could change the balance of power in the wizarding community.
One interesting plotline could be a character discovering a new form of shadow magic that has been long forgotten in the wizarding world. This could lead to a race against time to master it before the dark forces do.
Perhaps in a fanfiction, the Minister of Magic is under the influence of a powerful dark charm, and Harry Potter has to find a way to break it without causing chaos in the wizarding world. He might have to team up with unlikely allies from different houses at Hogwarts. This could involve a lot of character development and exploration of the relationships between different wizarding factions.
One interesting plotline could be Harry leading a secret resistance against the Ministry's unjust laws. For example, he might gather a group of like - minded witches and wizards to oppose the Ministry's restrictions on Muggle - born rights. Another could be a situation where the Ministry is under the control of a dark force, and Harry has to expose the truth while being hunted by the very institution he once trusted. And there might be a plotline where Harry uses his unique connection with magic, perhaps something related to his connection with Voldemort's magic, to outwit the Ministry's powerful magic - based security systems.
One interesting plotline could be exploring Harry's true magical origin in more depth. Maybe he has some ancient magic in his bloodline that was previously unknown. Another could be how his birth affects the entire wizarding world's future in a different way than in the original series.
One interesting plotline could be Harry discovering ancient wandless magic spells hidden in the Forbidden Forest. Maybe he stumbles upon a long - forgotten magical grove where the magic is so pure that it doesn't require a wand. He then has to learn how to control this new - found power without the guidance of his usual wand - based magic training.
A really cool fanfic idea could be that the Minister of Magic is secretly under the influence of a powerful dark wizard. Harry Potter suspects something is wrong and starts his own investigation. Along the way, he discovers old secrets about the Ministry and has to fight against not only the dark influence but also the Ministry's bureaucracy that is trying to cover up the truth. This would involve a lot of mystery, action, and exploration of the complex power dynamics in the wizarding world.
There might be a plotline where a group of fans of the 'Harry Potter' series create their own magical society based on the concepts in 'for love of magic fanfic'. They explore different forms of love - platonic, romantic, and love for magic itself - and how these can be used as a powerful force against dark magic.
