In the 'Harry Potter Stealing Vaults' fanfic, a plotline might involve Harry finding out that there are secrets in the vaults that are crucial for the wizarding world's future. So, he decides to steal from the vaults because the proper authorities are too corrupt or too slow to act. It could also be that he's on a quest to uncover his family's lost heritage which is locked away in those vaults, and stealing is the only way he can access it.
One plotline could be that the vaults are actually holding something that is endangering the magical balance, like a cursed object that's slowly spreading dark magic. Harry, being the hero he is, decides to steal the vaults to get to this object and destroy it. He might face many challenges along the way, such as complex magical security systems, and he may have to team up with some unlikely allies, like a goblin who has his own reasons for wanting the vaults emptied.
Obviously, Harry Potter is one of the main characters. There might also be Hermione Granger as she often helps Harry in his adventures. Ron Weasley could be there too, providing his loyalty and some comical relief. Additionally, there could be some original characters created specifically for this fanfic, like a powerful wizard who guards the vaults or a mysterious figure who is secretly guiding Harry's actions.
There might be a story where a group of Hogwarts students stumble upon a secret vault that is protected by a series of extremely difficult puzzles. They have to use their combined knowledge of magic, from Transfiguration to Potions, to get through. For example, they might need to transform a key into a liquid to pour into a keyhole that only accepts substances with a certain magical property. This not only tests their magical skills but also their ability to work as a team.
Well, one plotline could be the main character, perhaps a new healer at Hogwarts, dealing with magical maladies that are beyond the usual. For example, they might encounter a spell - induced illness that spreads among the students and has to find a unique cure using both traditional and forgotten healing methods.
Perhaps in the fanfic, Harry is turned into a snake for a period of time. As a snake, he experiences the wizarding world from a different perspective. He has to learn how to survive as a snake while still trying to fulfill his role in the fight against Voldemort. He might encounter other snakes that are either friendly or hostile, and he has to use his wits to deal with them.
Since this is an improper concept for the Harry Potter world, there are no so - called 'good' plotlines in such fanfic. We should uphold the positive values that J.K. Rowling intended in the original work, rather than exploring such unseemly fan - created ideas.
Well, perhaps in 'the king harry potter fanfic', there's a plotline where Harry discovers a long - lost magical artifact that gives him the power and status of a king. This could lead to him having to face off against old enemies who now see him as an even greater threat. And his friends from Hogwarts might have to band together to protect him as he adjusts to this new role. Also, it could involve new magical creatures being drawn to him because of his new - found king - like aura.
A great plotline in some fanfics is the discovery of new spells and magic. It could be that a long - lost spellbook is found, and the characters start to experiment with spells that are more powerful and dangerous than what they are used to. This could lead to all sorts of situations, from accidentally creating new magical disasters to using these spells to fight off new, unexpected enemies.
One interesting plotline could be Voldemort being redeemed. It's a really different take as in the original books he's pure evil. But in fanfic, some writers explore what if he had a change of heart.
In 'Harry Potter and the Legacy of Hogwarts Fanfic', a possible plotline is the exploration of the Forbidden Forest in more depth. The main characters might discover new magical creatures that were previously unknown or thought to be extinct. There could also be a plotline about a magical disease that starts to spread among the students and teachers, and they have to find a cure using their knowledge of magic. Another interesting plotline could be about a secret society within Hogwarts that has been operating for centuries and the main characters get involved in it, uncovering its true purpose and history.
One interesting plotline could be the younger twin having a unique magical ability that even Harry Potter doesn't possess. For example, the ability to communicate with magical creatures on a deeper level.
