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.
Dumbledore, even in spirit form, could visit Harry. Dumbledore has always been a guiding figure for Harry, and his wisdom could still reach Harry in the tent. He might appear as a ghostly figure to give Harry some crucial advice about the future or how to handle his current situation.
It could be self - expanding. So when Harry enters, it can adjust its size according to the number of people or the amount of stuff he has with him. For example, if he has a lot of friends joining him, it can become as large as a small mansion inside.
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.
Perhaps he buys it from a traveling wizard merchant. These merchants sometimes have rare and special items that are not easily found in regular stores. They could cross paths with Harry during one of his adventures outside of Hogwarts.
Sometimes, new original characters are created in the fanfiction. These could be young wizards or witches who discover the magical tent and embark on their own journey. They might interact with the well - known characters from the original series, like getting help from Dumbledore or facing challenges set by Voldemort.
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.
He could try to trick the Snatchers into giving them back. Maybe he pretends to be more injured or incapacitated than he really is, and when they come close to check on him, he quickly grabs his glasses back.
Hermione would surely visit. She'd be there with a stack of books, ready to help Harry catch up on his studies while he recovers. And Ron would be right beside her, probably with some treats from the Hogwarts kitchen.
There are fanfictions where the Snatchers don't even notice Harry's glasses at first. But then, when they do, they might mistake them for something valuable or magical. However, Harry could use this misunderstanding to his advantage. For example, he could pretend that the glasses are a powerful magical relic that would cause great harm if they were damaged, which might make the Snatchers hesitant to touch them.
One idea could be that the magical tent becomes a portal to different magical realms. For example, it could lead to a hidden dimension full of ancient spells and forgotten magic. Another could be that the tent has a mind of its own and helps the characters in unexpected ways during a dangerous adventure, like providing magical defenses when they are under attack.
In fanfiction, the glasses in the tent might be a key to a mystery. They could be the only clue to finding a hidden treasure or solving a riddle. Their presence in the tent could be a starting point for a grand adventure. For instance, the tent could be located in an ancient and magical place, and the glasses start to act strangely, leading Harry to explore the area further and uncover secrets that have been long buried.
