What are some interesting plot ideas for a Harry Potter Room of Requirement fanfic?

A plot could be that Harry and Hermione are looking for a way to bring back some of the lost memories of the students who were affected by a powerful forgetfulness charm during a battle. In the Room of Requirement, they find a magical device that can restore memories, but they have to go on a quest within the room to find the power source to activate it. Another idea is that they use the room to train for a magical tournament that's different from the Triwizard Tournament. They face all kinds of magical challenges created by the room itself, and in the process, they grow closer as friends and develop their magical skills even further.

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.

One idea could be a story about the Gryffindor Quidditch team in the locker room before a big match. Maybe there's some friendly banter among the players, like Harry Potter trying to boost the team's morale with a humorous speech. Another could be a story of a new student accidentally stumbling into the Slytherin locker room and the reactions of the Slytherin students.

Another scenario is that the room transforms into a time - traveling portal. Harry and Ginny accidentally step into it and end up in a different era of Hogwarts. They have to figure out how to get back while also dealing with the different magical rules and customs of that time. This adventure tests their relationship and their knowledge of magic.

A possible plot for a Harry Potter shower room fanfiction could be that the shower room is haunted by the ghost of a former student who was wronged in that very place. Harry, being the brave one, decides to communicate with the ghost and find out what happened to help it move on. Another idea is that the shower room's water has some special magical properties that start affecting the students' magical abilities in unexpected ways. For example, it makes Neville suddenly able to perform advanced herbology - related spells. And a third idea is that the Marauders once hid a prank - related map in the shower room that Harry discovers, and it leads him on a wild adventure around Hogwarts.

One possible plot could be that Harry and Ginny discover a hidden part of the Room of Requirement. Maybe they are looking for something specific, like a powerful magical artifact left behind by an old wizard. As they explore, they face some magical challenges and traps. Ginny's quick thinking and Harry's experience help them overcome these obstacles. In the process, their relationship deepens as they rely on each other for support.

Well, you could have a fanfic where Voldemort uses DND - style dark magic to open portals to other dimensions. The Order of the Phoenix has to quickly learn DND - style combat and magic rules to fight off the new threats that come through these portals. Harry could be sent on a special mission to find a DND - style mage who can teach them the counter - spells. Meanwhile, the Death Eaters are also trying to master this new form of magic for their own evil purposes. This would create a really exciting and unique story.

Perhaps a plot where the protagonist can choose to either side with the Ministry of Magic during a time of political unrest within the wizarding world or join a rebel group. This would involve different magical battles and moral dilemmas depending on the choice. In the 'harry potter cyoa fanfic', this could show different aspects of the wizarding society that we don't often see in the original books.

A cool plot for a Harry Potter Twilight fanfic could be a competition. The wizards from Harry Potter and the vampires and werewolves from Twilight compete in a series of challenges. These challenges could test both magic and the unique abilities of the Twilight characters. Or perhaps a love triangle between a Harry Potter character, a Twilight vampire, and a Twilight werewolf. It would be interesting to see how the different cultures and powers interact in matters of the heart.

Another plot could focus on the lives of the secondary characters from the original series. For example, Neville could be the head of Herbology at Hogwarts and discovers a new, dangerous plant that has some sort of connection to an ancient magic. The 'carry on fanfic' could then be about how he and his students deal with it, with some cameos from the main characters.
