What could be the plot in 'Harry Potter makes his own island' fanfiction?

In this fanfiction, Harry could be forced to create an island due to some kind of dark magic threat in the wizarding world. He uses his knowledge and the help of his friends like Hermione and Ron. They might design the island to have its own unique magical ecosystem. For example, they could create a special type of tree that produces potions - ingredients as its fruits. Harry could also make a school on the island for young witches and wizards who are in danger in the regular wizarding world.

Maybe Harry discovers a new and unique magic that only he can perform. This new magic could be the mark he makes. For example, he might find a way to combine different spells in an unprecedented way that gives him an edge in fighting the dark forces.

Maybe Harry, tired of the existing power structures in the wizarding world, starts his own empire. He could start by recruiting those who have been marginalized, like werewolves and half - bloods. He'd then use his fame and skills to establish a new order, one based on equality and true understanding of magic.

Hermione could be there. She would be really helpful in planning and organizing the island. For example, she might set up a system for categorizing all the magical knowledge and resources on the island.

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.

Maybe Harry uses magic to create an island as a secret hideout from the Dark forces. He could make it full of magical creatures and plants that he discovers during his adventures.

Well, perhaps Harry, tired of the wizarding world's chaos, decides to buy an island for some peace. He could use magic to build a unique, hidden mansion there. Maybe he'd invite his closest friends like Hermione and Ron to visit, and they'd have magical adventures on the island that are different from those in Hogwarts.

Well, one possibility could be that Harry discovers a hidden magical island. He might find new magical creatures there and learn unique spells to survive. Maybe he builds his own little wizarding home on the island.

Perhaps Harry builds the island to start a new school of magic. He could design it with unique classrooms, like ones underwater or in the treetops. He'd invite witches and wizards from all over to teach different forms of magic that were previously overlooked in Hogwarts.

One possible plot could be that Harry discovers the island is a magical place filled with ancient spells and potions. He might use it as a sanctuary away from the wizarding world's chaos, perhaps to study magic in peace and develop new spells.
