Often, Harry as a lord may have to deal with the political side of the wizarding world. He might face opposition from the old pure - blood families who don't want a 'half - blood' lord to have so much power. So, there could be a lot of intrigue and power struggles in the story.

He may also discover new magical abilities or artifacts associated with his Potter heritage that help him in his journey.
Well, perhaps one interesting development could be Harry exploring the new powers and responsibilities that come with being a lord. He might use his new status to reform the wizarding world in ways he couldn't before as just a student.
In some of these fanfictions, Harry might start exploring the dark art of necromancy secretly. He could be driven by a desire to bring back his lost loved ones, like his parents.
