One interesting plotline could be Harry's struggle with his newfound dark power while Hermione tries to bring him back to the light. For example, Hermione might use her vast knowledge of magic to find ancient spells that could reverse the dark influence on Harry. Another plotline could involve them facing off against their former friends who are now afraid of Harry's transformation. This would create a lot of tension and conflict in the story.
A possible plotline is that Harry, as the Dark Lord, decides to reshape the wizarding world according to his new ideals, and Hermione, though initially opposed, gradually comes to understand some of his motives. They could team up to fight against a common enemy that is even more dangerous than Harry's dark side, like an ancient evil that has been awakened. This would force them to work together and re - evaluate their relationship.
In some fanfictions, the plotline could be that Harry is influenced by a dark artifact which turns him into the Dark Lord. Hermione then embarks on a journey to find the source of the artifact's power in order to save Harry. Along the way, they encounter various challenges and secrets about the wizarding world that they never knew before. Their relationship evolves from Hermione being a rescuer to them becoming partners in a much larger battle against the dark forces that the artifact represents.
Well, there could be a plot where Harry, as the Dark Lord, has taken over Hogwarts and Ginny is part of a resistance group within the school. Their relationship becomes very complicated as they are on opposite sides, yet still have a deep connection. It could also be that Ginny discovers a prophecy that says only she can save Harry from his dark path, and she embarks on a dangerous journey to fulfill it.
One interesting plotline could be how Harry's relationships change. His friends might initially try to save him from the dark path, leading to intense emotional confrontations. For example, Hermione could use her vast knowledge to find a way to reverse whatever made Harry turn dark, while Ron might be more impulsive in his attempts to bring Harry back. Another plotline could involve the wizarding world's reaction. The Ministry of Magic would likely see Harry as a huge threat and try to stop him, which could lead to all - out war. And Harry himself might have new powers or a different understanding of magic as a dark lord, which could introduce unique magical elements into the story.
Another plot could involve them facing opposition from the traditional good side, like Dumbledore's Army remnants. They have to use their newfound dark powers and cunning to outwit their opponents. Maybe they start to realize that the line between good and evil isn't as clear as they once thought. As they fight, they also discover secrets about the wizarding world's past that make them question everything they knew.
Some fanfictions explore a different relationship dynamic between them. Maybe Harry has a problem that only Hermione can understand and help him with, and this brings them closer in a way that's different from their normal friendship. It could be something related to his connection with Voldemort or his family history.
In some fanfictions, their training might involve time - traveling. Maybe they go back in time to learn from the founders of Hogwarts. Harry could learn how to better control his connection to Voldemort through this time - traveling training, and Hermione could study ancient magic from the founders. This would add a whole new dimension to their skills and knowledge.
One possible plotline could be Hermione using her intelligence to create a stable and loving home environment for Harry. Maybe she helps him deal with his PTSD from his past traumas. Another could be them facing magical threats together as a family, with Hermione teaching Harry new spells and ways to protect himself.
One interesting plotline could be Harry and Hermione discovering a long - lost secret vault in Gringotts. Maybe it contains powerful magical artifacts that can change the course of the wizarding war. Another could be that they are on a mission to retrieve something from the vault that is crucial for their fight against Voldemort, like a spellbook with ancient and powerful spells.
One possible plotline could be that they are practicing magic for an upcoming difficult exam at Hogwarts. They might be working on advanced spells like the Patronus charm and Hermione is helping Harry perfect it.
One possible plotline could be that they escape from a dark wizard's lair. Maybe they use their combined magic skills and Hermione's extensive knowledge to find a secret passage out. Another could be escaping from a dangerous magical creature's territory by using clever spells and potions.
Perhaps a plot where they all become animagi and have to use their animal forms to solve a mystery in the Forbidden Forest. Draco as a sleek snake, Harry as a stag, and Hermione as an otter, they must navigate the forest's dangers and uncover the truth about a strange magical disturbance.
