A possible plotline could revolve around the idea that Acheron is actually a long - lost relative of Harry Potter. This discovery would lead to a whole new set of adventures as they explore their shared family history. They might find ancient family magic or secrets that were hidden away for centuries, which could either be a great boon or a dangerous curse depending on how they handle it.
One interesting plotline could be the exploration of a new magical bond between Harry Potter and Acheron. Maybe they discover a hidden magic that only they can access together, which helps them face a new dark threat in the wizarding world.
One interesting 'Harry Potter Acheron' fanfiction could be one where Acheron has some sort of magical connection with Harry Potter that was hidden for years. Maybe Acheron has the power to unlock a hidden potential in Harry that no one else knew about.
Perhaps Acheron gets transported to Hogwarts for some mysterious reason. Harry is the first to discover him and has to figure out how to deal with this strange, powerful being. Along the way, they start to understand each other's powers and learn from one another, forging an unlikely friendship.
Well, aside from Harry Potter and Acheron, other characters from the original 'Harry Potter' series often play important roles too. Hermione and Ron might be there to support Harry in his new adventures with Acheron. Dumbledore could also make appearances, perhaps guiding Harry and Acheron in their journey, especially if they are dealing with something that has to do with the greater good of the wizarding world.
In some fanfictions, there could be a plot where a goblin is on a quest to retrieve a stolen magical artifact from the wizarding world, and Harry gets involved. This could lead to a series of adventures as they work together, facing various obstacles and enemies. The goblin might also introduce Harry to parts of the magical underworld he never knew existed.
One interesting plotline could be a werepyre (a combination of werewolf and vampire perhaps) helping Harry Potter in his fight against Voldemort in a very unexpected way. Maybe the werepyre has unique powers that can counter some of Voldemort's dark magic.
Well, there might be a plotline where the gamer - inspired character creates their own magical guild within Hogwarts. They recruit other students based on their unique magical skills, much like forming a team in a game. Together, they embark on quests to find hidden magical artifacts that could change the balance of power in the wizarding world. This not only adds a new dynamic to the familiar Hogwarts setting but also brings in the cooperative and competitive elements often found in games.
Another plotline could involve the amulet having the power to travel through time. Harry uses it to go back in time to learn more about Voldemort's past, in order to find a weakness. This would be a very exciting and complex story, as he would have to be careful not to change the present too much while in the past.
One interesting plotline could be the emancipation of house - elves in a more radical way. Maybe a group of wizards and witches, inspired by Hermione's SPEW, take more forceful actions to give house - elves full rights and freedom, which could lead to a lot of conflicts with the traditional pure - blood families who are used to having house - elves serve them.
One interesting plotline could be a jumper that has special powers. For example, it might be able to transport the wearer to different magical locations in the Harry Potter universe. Another could be a jumper that changes its appearance based on the wearer's mood or the magical situation around them.
Some fanfictions might explore the political power struggle between different pure - blood families. They could show how these families vie for influence within the Wizengamot. It's like a game of thrones in the wizarding world, with each family using their own strategies to gain more power and control over magical policies.
