One possible storyline could be that Harry is on the run from dark forces again and the tent serves as his only safe haven. He might be using magic to conceal the tent and make it a cozy, self - sufficient living space, with magical wards all around it for protection.
His best friends, Ron and Hermione, would most likely visit him. They have always been by his side through thick and thin, so they would find a way to get to the tent to check on him, bring him supplies, and offer their support.
Maybe in this fanfiction, Harry Potter lives in a tree to hide from his enemies. The tree could be magically protected, providing him a safe haven.
One possible storyline could be the children of the original characters starting their own adventures at Hogwarts. They might face new threats that are related to the past but in a different way. For example, a new dark wizard could be trying to revive the ideas of Voldemort and the kids have to stop it using the knowledge passed down from their parents.
One possible storyline could be that the Dursleys' pet, perhaps their cat, discovers Harry's wizarding abilities before the Dursleys do. It might then have some comical or tense interactions with Harry, like trying to stop him from using magic in the house for fear of getting in trouble itself.
Perhaps in the fanfiction, Harry discovers that his grandparents had a hidden magical legacy. They had been working on a powerful charm to protect the Potter family long before Harry was born. Harry finds clues about this charm and with the help of his friends, he tries to complete it, believing it could be the key to finally defeating Voldemort.
Well, it might also lead to a change in the dynamic among the characters. For example, Hermione or Ron might have to take on a more protective role towards Harry. They would need to be his eyes in a sense, guiding him and making sure he doesn't get into more trouble. Plus, it could be a plot device for the author to introduce some sort of magical solution to the problem, like a spell that temporarily restores Harry's vision without his glasses.
In the fanfiction, Bella could be involved in a mystery within the orphanage. There might be a secret room or a strange event that keeps occurring, and she takes it upon herself to solve it, which could also lead to her finding out about her real family or some other important aspect of her past.
Another storyline could be that Harry goes to Bulgaria to hide from the threats in the UK wizarding world. While there, he has to adapt to a new culture and way of life. He could start teaching at a Bulgarian wizarding school, sharing his knowledge of Defense Against the Dark Arts. He might also fall in love with a Bulgarian witch and have to deal with the cultural differences in relationships.
One possible storyline could be that Steven Stone, with his knowledge of stones and gems, discovers some magical gems in the Harry Potter universe. These gems could have unique magical properties that are unknown to the wizards. He teams up with Harry Potter to protect these gems from dark wizards who want to use them for evil. For example, the gems might be able to enhance spells or open portals to other magical dimensions.
In this fanfiction, it could be that Hogwarts has been shut down due to some great danger. Harry Potter then decides to gather a group of like - minded young wizards and witches. They form their own makeshift magical school in a hidden location. They have to learn magic without the guidance of Hogwarts' professors, so they rely on old magic books and their own wits to develop their magical abilities and face the threats that led to Hogwarts' closure.
