Well, a possible plot is that Andromeda is on a quest to find a magical artifact that Rabastan also wants. They cross paths and initially battle for it. However, during their encounters, they realize that there are greater threats in the wizarding world that they should be concerned about. So, they join forces. As they travel together, they learn about each other's pasts and dreams. Rabastan might be struggling with his family's expectations and Andromeda with her identity as a Black who has turned away from the family's dark traditions. This journey of discovery and cooperation could form the core of the fanfiction.
One plot idea could be that Rabastan, in an alternate universe, is forced to team up with Harry Potter to fight a common dark magic threat that endangers both the wizarding world and the Death Eaters' own interests. This would create a lot of tension as they have to overcome their natural enmity.
Their relationship could develop in a non - romantic way through a mutual respect for each other's magical abilities. For example, they could be part of a magical research group where they have to collaborate on a project. Rabastan might be an expert in Dark Arts defenses, and Andromeda could be well - versed in charms. By working together, they learn to value each other's skills without any romantic feelings. Another way is if they are both involved in a wizarding community project, like rebuilding a damaged wizarding village. They have to coordinate efforts and over time, form a friendship based on their shared goal.
One possible plotline could be the struggle Harry faces within the wizarding community due to his marriage to Rabastan. People might be suspicious and distrustful, thinking he has turned to the dark side. Another could be how Harry tries to redeem Rabastan, or perhaps they discover a common goal that unites them against a new, emerging threat in the wizarding world.
One possible plot could be that it's an alternate universe where the war ended differently. Harry, in his quest for peace and to end the cycle of hatred, decides to marry Rabastan Lestrange as a political move. He hopes to reform the pure - blood supremacist ideas within the Lestrange family. They might start off as strangers, but gradually learn about each other's pasts and find common ground in their losses. Harry could use his influence to bring Rabastan into the light side, and together they could work towards rebuilding the wizarding world in a more inclusive way.
A plot might revolve around the wizarding community's reaction to Harry's new identity. Some might fear that he has the same dark tendencies as the Lestrange family. This could lead to Harry being ostracized at Hogwarts. Meanwhile, he might start to notice some strange powers or abilities within himself that he can't explain. He then tries to find out if these are related to his Lestrange heritage. Along the way, he forms new alliances with some unlikely characters who are also interested in the secrets of his family.
The theme of redemption also pops up a lot. Writers like to imagine if Rabastan could ever atone for his dark deeds. It could be through helping the good side or by making amends to the victims of the Death Eaters' actions. This gives the character more depth and makes the story more engaging.
One idea could be the daughter's struggle to break free from the dark reputation of the Lestrange name while also dealing with her mother Hermione's fame as a hero. She might face discrimination in the wizarding world due to her family name, but strive to prove herself through her own magical abilities and kind heart.
One idea could be a story where Hermione has to work with the Lestrange brothers in a dangerous mission to retrieve a powerful magical artifact. They start off distrusting each other but as the mission progresses, they learn to rely on one another's skills. Another plot could be that Hermione discovers a long - hidden connection between her family and the Lestranges, which forces them to interact in unexpected ways. Maybe she has to use her intellect to prevent the brothers from falling back into their dark ways.
One idea could be that Hermione discovers a hidden connection between the Lestrange brothers and an ancient magic. Maybe she stumbles upon a secret library that was once in the possession of the Lestrange family, and the brothers are also after the knowledge there. They start as rivals but gradually form an unlikely alliance as they realize they need each other to unlock the secrets. Another plot could involve Hermione trying to redeem the Lestrange brothers. Since they come from a dark family background, she could use her intelligence and compassion to show them a different path. For example, she could introduce them to the idea of using magic for good in ways they had never considered before.
One plot idea could be that in an alternate universe, Rodolphus, after realizing the error of his ways in the wizarding war, tries to make amends by protecting Hermione from a new dark threat. This could lead to a begrudging partnership that slowly turns into an unexpected friendship or more.
