Who might be training Harry Potter secretly in the fanfiction?

There are indeed 'Harry Potter is secretly married' fanfictions. Fanfiction writers often take creative liberties with the characters. They might imagine a scenario where Harry has to keep his marriage a secret due to various reasons such as threats from dark forces or to protect his family. This kind of fanfiction can range from light - hearted and romantic to dark and full of intrigue, depending on the writer's vision.

It could be his loyal owl, Hedwig. She might be staying with him in the attic, providing comfort and also being a messenger for him when he needs to communicate with his friends outside.

It could be Draco Malfoy. In some fanfictions, the dynamic between a female Harry Potter and Draco is reimagined, and they might end up secretly married as a way to show a new kind of relationship between the two formerly antagonistic characters.

Well, in fanfiction, Neville Longbottom could be one of the visitors. He and Harry could exchange gardening tips as they explore the manor's gardens. Additionally, Dumbledore's portrait might be magically transported to Potter Manor, and he could offer his wisdom and guidance to Harry as he lives in the manor. And of course, Hagrid might come with some magical creatures to show Harry, adding more excitement to the manor.

Another possibility is that she's secretly married to a character from a different magical world. Maybe a powerful wizard from a far - off land. This would add an element of mystery and adventure to the story. It could be that they met during one of Hermione's research trips or some sort of magical accident brought them together, and they got married in secret for reasons related to the politics of their respective worlds.

His friends from Hogwarts, like Ron and Hermione, are likely to help. Ron could bring his family's practical knowledge of wizarding homes and Hermione would contribute with her extensive research skills.

Dumbledore could be the instructor. He might have a special training program in mind for the students. He could teach them about the deeper mysteries of magic, like the secrets of the Hallows or the true nature of the Deathly Hallows. His wisdom and experience would make him an excellent teacher for the students during the summer training.

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.

He might meet Canadian witches and wizards. There could be a friendly wizard who shows him around the Canadian wizarding community.

He might meet international aurors. These are highly skilled wizards from different countries who are experts in dark wizard catching. They could teach Harry some new combat spells.
