What could be the plot of the 'Harry Potter lives in a trunk' fanfiction?

Well, it could be that the trunk is a magical trunk with all sorts of hidden compartments and powers. Maybe it has a self - cleaning function, or it can transform into a small shelter when Harry is in danger. It could also be filled with rare magical items that help him in his adventures at Hogwarts.

It could be Hagrid. Hagrid is always looking out for Harry and giving him things. He might come across this special trunk during one of his travels in the Forbidden Forest or in some wizarding market and think it would be perfect for Harry.

It could be that the manor trunk is enchanted in a special way. In the fanfiction, it might serve as a portal to another dimension or a time - locked chamber. Harry could accidentally open it and find himself in a different era of the wizarding world, having to figure out how to get back while also dealing with the unique challenges and characters of that time.

In the learning trunk, there might be a magical map similar to the Marauder's Map but with more detailed information about the Hogwarts library. It could show hidden sections and the location of books related to specific spells or magical theories. There could also be a set of magical crystals that when held, can transport him into virtual scenarios to practice spells and combat skills in a safe environment.

There could be compartments filled with clothes that magically adjust to the wearer's size and the weather. One compartment might hold a set of invisibility cloaks, and another could have a collection of magical maps. Some compartments could be used to store portraits of important wizards and witches that can communicate and give advice.

Harry is the central figure for sure. Neville Longbottom could play a role. He might be one of the few who know where Harry is hiding and is trying to protect the trunk from being discovered. Hagrid could also be involved. He might bring Harry some food and supplies while he's in the trunk. And there could be some mysterious old wizard or witch who has some connection to the trunk and its magic.

I'm not sure specifically as there could be many different takes in such a fanfiction. It might involve Harry and his mom having some sort of unique adventure while living in a trunk. Maybe they discover a hidden magical world within the trunk or use it as a refuge from the dark forces in the wizarding world.

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.

One possible plot could be that Harry is turned into an animal, like a stag, which is his Patronus. He then has to navigate the wizarding world in this new form. He might use his animal instincts to discover hidden secrets or evade his enemies. For example, he could sneak into places unnoticed as an animal, which he couldn't do as a human. He might also communicate with other magical animals in a way he never could before, and they could help him on his quests.

It could be that after a great battle, Harry Potter decides to retreat to the woods to heal both physically and mentally. While in the woods, he stumbles upon a hidden magical community that has been living there in isolation for centuries. He then becomes part of this community, sharing his knowledge of the outside wizarding world and learning their unique ways of magic which are deeply connected to nature.
