Well, first of all, incest has no place in the 'Harry Potter' world. J.K. Rowling created a magical universe based on positive values. Incestuous ideas go against the spirit of the original work. Instead of thinking about such inappropriate ideas, we can focus on exploring the wonderful magic, the growth of characters, and the complex relationships that are already presented in a proper way in the series. For example, the friendship between Harry, Ron and Hermione is a great aspect to delve deeper into in fanfic.
It's simple. Incest is just not in line with the moral fabric of society and the positive values of the 'Harry Potter' series. The books are about things like friendship, loyalty, and good vs. evil, not inappropriate relationships.
A great plot idea could be that the dragoness is an ancient being that has knowledge of a long - forgotten magic. Harry Potter discovers the dragoness while on a quest to learn more about a particular type of magic for his studies. The dragoness then becomes his mentor in this new form of magic, and they embark on a journey to unlock the secrets together. This would be a story of learning, discovery, and friendship.
A great 'Harry Potter fanfic' idea might be a story that delves deeper into the relationship between Snape and Lily. Maybe a fanfic where Snape has a chance to change the past and save Lily in a different way. Another idea is to write a fanfic about the ghosts in Hogwarts and their backstories, like how they died and why they chose to stay at the school. Additionally, a story where the Weasley twins open a magical joke shop in a different country and the challenges they face there would be really interesting.
One interesting idea could be a fanfic that focuses on the Marauders' time at Hogwarts. It could explore their pranks, friendships, and how they came to be the legends that we hear about in the original books. For example, showing how they created the Marauder's Map in more detail.
One interesting idea could be exploring the lives of the minor characters more in - depth. For example, what was Neville Longbottom's life like during the summers at home? Another idea is to create an alternate ending to the series. Maybe Voldemort could have been redeemed instead of defeated. Also, a fanfic could focus on the magical creatures and their own society within the wizarding world.
One interesting idea could be a fanfic where the Marauders attend Hogwarts during modern times. They'd have to deal with things like smartphones and social media while still maintaining their mischievous ways. Another could be a story that focuses on the lives of the house - elves after the events of the books, perhaps exploring their newfound freedom. And a third idea could be a fanfic about a new dark wizard emerging in the wizarding world years after Voldemort's defeat, and how the new generation of Hogwarts students respond.
One idea could be exploring how the eldritch elements interact with the magic in Hogwarts. For example, an eldritch force might seep into the Forbidden Forest and start to corrupt the magical creatures there, leading to strange and dangerous new behaviors among them. Another could be about a student who discovers an eldritch spellbook in the Room of Requirement and has to deal with the unforeseen consequences of using its spells.
One idea could be a letter from a Hogwarts student to their parents explaining their first experiences in the Forbidden Forest. It could detail the strange creatures they saw and the sense of danger and excitement.
You could also create a fanfic centered around the Thestrals. For example, a story where a group of students discover a hidden colony of Thestrals and have to protect them from dark wizards who want to use their powers for evil. Since only those who have witnessed death can see Thestrals, it could add an interesting mystery element to the story.
One interesting idea could be rebuilding Hogwarts in a more modern way. Maybe with updated classrooms that have advanced magic technology for teaching. Another idea might be rebuilding the relationships between characters in a different way, like Harry and Draco becoming friends earlier in the story.
