Dumbledore could still play a role, perhaps as a mentor from the shadows. Even though he's no longer alive in the original series, in fanfiction, his wisdom could be passed on through memories or portraits. He might offer cryptic advice to Harry about how to use his new power for the greater good and avoid the temptations that often come with lordship.
It could be about Harry Potter finding out he has a claim to multiple lordships within the wizarding world. Maybe he discovers some long - lost family connections or ancient rights that entitle him to these positions of power and influence.
Well, one interesting plot could be Harry Potter using his newfound lordship status to reform Hogwarts' old and sometimes unfair traditions. He might use his influence to improve the living conditions of house - elves within the school, as a lord could have the power to make such changes.
Often, you'll see Harry Potter himself. He might be involved in helping a muggle adjust to their new lordship in the wizarding world.
Harry Potter is often a central character. Given his status as the Boy Who Lived, his connection to the wizarding world makes him a natural fit in stories about lordships. Hermione Granger could also be involved, using her intelligence to navigate the political intrigue. And of course, Ron Weasley, as Harry's best friend, would be there to support and get involved in the adventures related to the lordships.
Hermione could be one of the main characters. She would be very helpful with all her knowledge of spells and magic theory. She could assist Harry in planning the layout of the village and ensuring that everything is in order.
I'm not sure specifically as I haven't read that particular fanfic. But it could potentially be about some form of noble or magical lordships that Harry discovers during the trial in the fan - created story.
There could be Hermione and Ron. Since they are Harry's best friends in the original series, they would likely be important characters in this fanfiction too. They might be curious about Ducky and his relationship with Harry, and could even get involved in some of the adventures that are related to Ducky's past or his influence on Harry.
Hermione could be a main character. She might be initially skeptical about Harry singing muggle music, but then she gets interested in the cultural aspect of it and starts researching the history of the muggle music Harry likes.
There could be an original character who is a descendant of the Uchiha that somehow ends up in the wizarding world. This character could teach fem Harry Potter about the Uchiha ways. Also, Dumbledore could play a role as he always encourages Harry's exploration of different knowledge, and he might be curious about the Uchiha knowledge that Harry is so interested in.
One plot point could be Harry finding an old family heirloom that is the key to proving his claim to a certain lordship.
