Dumbledore, if he were still alive in the fanfiction, could be an ally. His wisdom and knowledge would be very useful for building a kingdom. Also, the Order of the Phoenix members might support Harry. They are all about fighting for what's right, and Harry's new kingdom could be seen as a new hope for a better wizarding world.
His friends Hermione and Ron would most likely be his allies. They have been with him through thick and thin in the original series.
Ron could also be a great ally. His loyalty and courage would be important. He might be in charge of security, using his skills in wizard chess to plan out defensive strategies. And of course, the Weasley family in general could offer a lot of support, with their various skills and connections in the wizarding world.
Well, in this fanfiction, Harry might build a kingdom in a hidden location, perhaps an uncharted island. He would have to use powerful spells and his knowledge of magic to construct buildings, set up defenses, and form a government. He could also invite his friends like Hermione and Ron to help him, and together they would make laws that are fairer than those in the wizarding world we know from the original books.
Dumbledore, even if in spirit or through some magical means, could be an ally. His wisdom and foresight could guide Harry in making important decisions for the kingdom. Also, the house - elves, if Harry treats them fairly and gives them freedom and a place in the kingdom, could be loyal allies. They could take care of the day - to - day running of the castle or important buildings in the kingdom, using their unique magical abilities.
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.
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.
Hermione would definitely be one of his top allies. Her intelligence and knowledge of magic and history would be invaluable in helping Harry rule. She could advise him on laws and policies, especially those related to education and the treatment of non - human magical beings. Ron would also be an ally. His loyalty and his understanding of the wizarding world's less - sophisticated side could help Harry connect with the common wizards.
Hermione would definitely be one of his allies. She is smart and resourceful and would be able to help Harry navigate the new political and magical situations he faces as a prince. For example, she could research ancient laws and prophecies related to his new status.
Maybe an old wizard who has been secretly studying the combination of different magical universes for years. This wizard could have made some initial attempts at building a lightsaber - like weapon in the past and can share his experiences and mistakes with Harry. He would teach Harry about the balance between the light and dark side of this new form of magic, just like the Jedi teachings in Star Wars.
Hermione would likely be one of his allies. She's intelligent and has a strong sense of justice, always having been interested in the rights and wrongs of the wizarding laws. She could provide Harry with valuable research and advice.
Ron could also be an important ally. His loyalty and courage would be great assets. He might be in charge of security or diplomatic relations with other magical communities, using his Weasley charm to smooth things over.
