It's possible that the main characters could include some powerful wizards who are made into lords in the fanfiction. Their wives could be witches with special talents. Maybe there's a lord who is a powerful dark wizard turned good, and his wife is a healer. The relationships between these characters, their goals, and how they interact with the wizarding world around them would be central to the story.
Well, apart from Harry, you'll often find characters like Draco Malfoy's family lords. They are important in the wizarding hierarchy. Also, the Weasley family could potentially have some sort of lordship connection in some fanfictions. And then there are the more ancient and powerful families' lords who might be brought into the story to create new power dynamics. For example, the Black family lords. Their presence can bring in a lot of the old - fashioned wizarding ways and secrets that add depth to the fanfiction.
One possible plotline could be how the multiple lords interact with their respective wives in different magical scenarios. For example, they might work together to solve a mystery within the wizarding world that threatens their families and the magical community at large.
Obviously, Harry Potter would be one of the main characters since it's about him being a multi animagus.
It's likely that Harry Potter himself would be one of the main characters. Since it's related to the Harry Potter universe, he would probably be at the center of the story, exploring the multi - dimensional trunk. Hermione might also be there, using her intelligence to figure out how the trunk and the different dimensions work.
A prevalent theme in 'Harry Potter multi wives fanfiction' is loyalty and jealousy. With multiple partners, there are often storylines about how the characters deal with feelings of jealousy towards each other and how they maintain loyalty to Harry. Also, the integration of different magical heritages and how they interact within the relationship is a common theme.
Harry Potter is often a main character. Since he's the central figure in the original series, it's natural for him to be involved in fanfiction about lordships. Hermione Granger might also be there as she is Harry's closest friend and often gets involved in important matters. Ron Weasley could be another, as he's part of the trio.
In addition to the regular Harry Potter crew, there could be a character who is a native of the 'Lord of the North' and acts as a guide for Harry and the others. This character could have unique magical abilities related to the northern environment, like being able to control ice or snow magic, and would play a crucial role in their adventures.
Another character that could be important is Snape. His relationship with Harry has always been complex, and with Harry's new identity, Snape might have a different attitude towards him. Additionally, characters from the Potter family that we haven't seen much of in the original series could be introduced to help Harry understand his Potter heritage better as part of his new role as Lord Potter - Black.
Obviously, Harry Potter would be one of the main characters. He would be the one most likely to interact with the concept of the 'Lord of Lightning'.
There could also be an original character who is a direct descendant of the Peverells. This character would be central to the story, as they navigate the wizarding world with their unique heritage. They might face challenges from other wizards who either envy or fear their connection to the Peverells.
