Well, often Harry will enter the Room of Requirement in fanfiction and find it full of secrets related to his family. Maybe there are portraits of his ancestors or diaries that reveal important family history and give him new insights into his own powers and destiny.
In some fanfictions, the Room of Requirement becomes a place for character development. For Draco, Hermione, and Harry, it could be a space where they confront their prejudices. Hermione might use the room's magic to show Draco the error of his ways, while Harry tries to find a middle ground. It's an interesting concept that often plays out in different ways in various fanfictions.
In a fanfic, the Room of Requirement could be a place where Harry and Ginny go to practice their magic together. They could be working on new spells or defensive techniques. Ginny could show Harry some of the unique magic she learned from her family. And in the process, their relationship deepens as they rely on each other and learn from one another.
One interesting plotline could be Harry and Ginny using the Room of Requirement to hide from Death Eaters during the final battle. They find secret passages and ancient spells within the room that help them in their fight. Another could be them using the room for romantic getaways, away from the prying eyes of Hogwarts students and teachers, where they share their deepest secrets and feelings.
The discovery can speed up the plot. If Harry finds the Room of Requirement and gets a super - powerful magical item from it, it can quickly change the balance of power in his fight against the bad guys.
Definitely Harry. He has so many secrets and needs throughout the series, and the Room of Requirement can be a place for him to fulfill those. For example, he might need a safe place to practice advanced defensive magic against Voldemort. Neville Longbottom can also be a common character. He could use the room to grow and study rare magical plants that he discovers are crucial for some kind of protection against dark magic. Draco Malfoy might be in some fanfiction too. He could be using the room to plot against Harry or to find a way to escape the dark path his family has set for him.
One interesting plotline could be about a character using the Room of Requirement to hide a powerful and dangerous magical artifact that was thought to be lost. The protagonist has to keep it a secret from both the good and bad wizards while trying to figure out what to do with it. Another could be students using the room to create a secret study group for a very advanced and restricted area of magic, and they have to avoid getting caught by the professors. And a third plotline might be about a character who accidentally discovers a hidden passage in the Room of Requirement that leads to an unknown part of Hogwarts filled with ancient magic and mysteries.
The Room of Requirement can be a place of shared adventures for them. As they explore the ever - changing room together, they rely on each other's skills and strengths. This mutual dependence makes their relationship grow. For example, if they face a dangerous magical creature in a part of the room, they work together to defeat it, and this shared experience brings them closer. It also gives them a chance to be themselves without the expectations of others around them at Hogwarts.
They might start off as just friends going into the room to study or find something for their next adventure. But as they spend more time in the room, sharing secrets and relying on each other, their bond deepens. For example, if they're in the room trying to solve a mystery, they'll have to trust each other completely, and that can lead to a stronger emotional connection.
One possible scenario could be that Harry, Daphne, Tracy, and Cho all find themselves in the Room of Requirement for different reasons. Maybe Harry is looking for a place to practice a new spell secretly. Daphne could be seeking a quiet spot to study some ancient magic texts she's found. Tracy might be there to hide from some bullies, and Cho could be in need of a place to mourn Cedric in private. They then start to interact, sharing their stories and perhaps forming an unlikely friendship or alliance.
