Well, in Harry Potter mechanic fanfiction, the idea of how magic is harnessed to power various devices is really cool. For example, the magic behind the Marauder's Map. Some fanfictions might detail the complex spells and mechanisms that make it possible to show the location of people within Hogwarts. Also, the Animagus transformation could be seen from a mechanical - magic perspective, like how the body physically changes according to the magic rules in a more detailed, technical way.
One interesting concept could be the magical mechanics of flying broomsticks. In some fanfictions, they might explore how the broomsticks are enchanted to fly so smoothly and at high speeds. Another concept could be the workings of the Hogwarts Express. Fanfic authors might delve into the magical engineering that keeps the train running on its tracks and through the magical barriers.
One interesting concept could be exploring more about the Marauders' time at Hogwarts. Fanfiction might expand on their adventures, like pranks they played that were never mentioned in the original book. Another could be different interpretations of Sirius Black's escape and his relationship with Harry during that time.
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 exploring new magical creatures in the Harry Potter kingdom. Maybe there are some hidden species that haven't been discovered in the original series. Another could be alternative forms of magic that are unique to the fanfiction's version of the kingdom. And also, new relationships between different houses or characters can be quite fascinating.
One interesting concept could be the use of magic in relation to physical laws. For example, how spells might interact with gravity. Maybe a levitation spell actually counteracts the force of gravity in a way that can be explained through some made - up 'physics' in the fanfiction.
Well, some fanfictions play with the idea of blood magic in relation to family bonds. They might show how the blood of one's ancestors can be a source of hidden power or knowledge. For instance, a character discovers that their long - lost relative had a special blood - related spell that can only be activated by someone with their exact bloodline. It adds an element of mystery and heritage to the story.
One interesting concept could be the merging of the magical world of Harry Potter with the demon - slaying elements of Sparda. For example, a character from the Harry Potter universe might gain the power of Sparda and use it to fight dark wizards in a new and unique way. It could also involve crossovers where characters from both worlds interact, leading to unexpected alliances and conflicts.
One interesting concept could be the way animism is incorporated into the magical creatures. For example, how they might have their own spirits or consciousness that is more in - depth than what's shown in the original series. Maybe the hippogriffs have a collective spirit that influences their behavior towards wizards.
Another concept could be the inflation of Hogwarts itself. The castle growing larger and larger, with new and strange rooms and corridors appearing. This could lead to new mysteries for the students to solve, like finding a hidden chamber in the newly - inflated part of the castle that holds a powerful magical artifact.
Another concept is the idea of prophecies being manipulated. In some fanfictions, dark wizards or witches try to change the outcome of the prophecy by interfering with the events or people involved. This can create a lot of tension and drama as the characters fight against this manipulation.
In 'harry potter daywalker fanfiction', there might be the concept of a daywalker being an outcast in the wizarding society. Since the wizarding world is so different from the Muggle world where the idea of a daywalker might be more associated with vampiric lore. This outcast status could lead to a story about acceptance and finding one's place, while also dealing with the unique powers and drawbacks of being a daywalker.
