Another idea in Harry Potter fanfiction could be that blank pages are the result of a powerful curse. A dark wizard has cursed all the books in a library so that any page that contains information about a certain powerful magic becomes blank. The main characters then have to find a way to break the curse and retrieve the lost knowledge.
They could be a canvas for new spells. A young witch might find a blank - page book that has the ability to absorb and hold new spells. She starts experimenting, writing down her ideas, and the book brings those spells to life. This could create a whole new area of magic study in the fanfiction world.
Some fanfictions in Harry Potter 2 might play with the idea of the basilisk having different powers or weaknesses. It could also explore the idea of a hidden connection between Ginny and the Chamber of Secrets that goes beyond what was in the original story. There might be fanfictions that change the role of certain characters, like making Neville a more central figure in solving the mystery of the Chamber.
One interesting concept could be the combination of magic from the Harry Potter world and the powers of demigods. For example, a character might use a wand to cast spells while also having the inborn strength or special ability of a demigod. Another concept could be the interaction between Hogwarts and a demigod - like camp. How would the rules and cultures of these two very different magical settings collide or coexist? Also, the idea of a demigod attending Hogwarts and having to hide their true nature from the other students and teachers can lead to some really exciting plot twists.
One interesting concept could be the unique powers or abilities that wardens have in the fanfiction world. For example, they might have the power to control certain magical creatures in ways not seen in the original books. Another concept could be the relationships between wardens and other characters like Hogwarts students or professors. They could act as mentors or protectors in new and different ways.
One interesting concept could be the creation of new magical illusions that are not in the original books. For example, illusions that can change the entire Hogwarts castle into a different setting like an underwater kingdom. Another could be illusions used for pranks that are far more elaborate and complex than what we see in the series, like an illusion that makes it seem like a dragon is flying around the Quidditch pitch.
One interesting concept could be alternative magical abilities for the characters. For example, giving Hermione the ability to control time in a different way than just using the time - turner. It adds a whole new layer to her character and the stories she can be involved in.
Well, a lot of times in 'harry potter pack fanfiction', there are unique interpretations of magic. Writers might come up with new spells or magical creatures that add a fresh twist to the wizarding world we know from the books. It's really cool to see how they expand on J.K. Rowling's original ideas.
One interesting concept could be exploring the spirits of the founders of Hogwarts. For example, how their spirits might interact with modern students or influence the current state of the school. Another could be delving into the spirits of magical creatures and how they view the wizarding world from their ethereal perspective.
In Harry Potter limbo fanfiction, a common concept is the idea of redemption. Characters who have made mistakes in the main story might find themselves in the limbo, given a chance to make amends. For instance, Draco Malfoy could be in the limbo, trying to come to terms with his actions during the wizarding war. Moreover, the limbo might be a place where the boundaries between life and death are blurred, allowing for some really unique plot twists.
One interesting concept is the transformation of characters' appearances. For example, Hermione might be magically transformed into a different species, like a mermaid. This could lead to new adventures and challenges for her as she has to adapt to a completely different form. Another concept could be the transformation of a character's personality. Maybe Harry could be magically altered to be more outgoing or less impulsive, which would change the way he interacts with his friends and enemies.
