Perhaps he barters with magical beings. He could offer his services in solving magical problems for them in exchange for rare building resources. For example, he might help a group of centaurs with a prophecy issue and in return, they give him enchanted wood or special stones. He may also get help from his friends who have access to different resources. Hermione might provide some rare books with building spells, and Ron could get some things from his family's old collection.
In the fanfiction, his self - built house may have a unique defense mechanism. Maybe it has a moat filled with a potion that makes any intruder forget their malicious intent. Also, the house could have a tower where Harry can practice advanced magic undisturbed, with a view of the magical landscape around. The interior might be decorated with items from his travels, like the Triwizard Tournament mementos.
Well, one possibility is that Harry Potter builds the school in a hidden location, away from the prying eyes of the Ministry of Magic. He might create a curriculum that focuses on both traditional magic and new, unique areas of study that he discovered during his adventures.
Obviously, Harry Potter himself would be one of the main teachers. He could teach Defense Against the Dark Arts, given his vast experience in that area. Hermione would be a great fit for teaching Transfiguration or History of Magic, as she has a deep knowledge of both.
Maybe Harry builds the house as a sanctuary for his friends who lost their homes during the war. He'd use his knowledge of magic and the help of Hagrid, who would supply some magical building materials. The house could have rooms that change according to the mood of the occupants, just like the rooms in Hogwarts.
Neville could be another helper. He has become quite skilled in herbology. He could help Harry by creating a magical garden around the house. The plants in the garden could be used for protection, like thorny bushes that keep unwanted visitors away, or for providing ingredients for household potions.
Maybe Harry decides to build a house in a magical forest. He uses his magic to gather the materials like levitating the logs. He might also face some challenges like protecting the construction site from magical creatures that want to play with the building supplies.
Well, the setting in the 'lord harry potter builds his lordship fanfiction' is important. It could be set in Hogwarts or the wider wizarding world. If it's Hogwarts, he might be building his lordship among the students and faculty. In the wider wizarding world, he'd be dealing with more complex issues. And of course, his own personal growth, from being just a wizard to a lord, in terms of his magical abilities, moral compass, and decision - making skills, is also a crucial element.
Hermione would be a great help. Her vast knowledge of magic and books could provide the necessary information for building the planet, like the right spells and magical theories.
Dumbledore might help in a spiritual or advisory way. Even though he's passed away, his wisdom could be passed on through memories or some magical means. Also, Hagrid could be a great help. He could assist in building areas suitable for magical creatures with his love and understanding of them.
