What are some interesting plot ideas for 'Harry Potter and Frozen' fanfiction?

Some interesting Frozen 2 fanfiction plot ideas could revolve around the idea of a magical item. For example, there could be a magical crystal hidden deep in the forest that has the power to either save or destroy both the forest and Arendelle. Elsa and her friends embark on a quest to find this crystal before it falls into the wrong hands. Another idea is that a dark force from outside the known world tries to invade the forest and Arendelle, and the characters have to unite not only the people of Arendelle and the forest but also other magical beings to fight against it. Also, a plot could be centered around a prophecy that was never fully revealed in the movie, and Elsa and Anna must figure out what it means for their future.

A possible plot is that a dark wizard from the Harry Potter world tries to take over Arendelle. Elsa and Anna have to team up with Harry and his friends to stop this threat. The Frozen characters would be introduced to the concept of the Deathly Hallows and Horcruxes. Elsa's ice powers could be a key factor in fighting the dark magic. Maybe her ice can counter some of the dark spells, and together they all discover new ways to combine their unique abilities to defeat the evil wizard.

A great plot for Frozen fanfiction could be a time - travel story. For example, Elsa is sent back in time to when her parents were young. She has to figure out how to get back to her own time while also trying not to change the past too much. But she might also learn some secrets about her family's past and her own powers. Another could be a story about a competition in Arendelle. Anna decides to hold a magical - themed competition, and people from all over come to show off their skills. Elsa has to judge, and in the process, she meets someone who seems to have powers similar to hers but uses them for evil. Anna, Elsa and Kristoff then have to stop this person.

A great plot for a Potter Manor fanfiction could involve a mystery that surrounds the manor. For instance, strange noises at night lead Harry to uncover a long - forgotten chamber. It could also be about Harry restoring the manor to its former glory, perhaps with the help of Hermione's research on ancient magic used in the construction of such manors.

One interesting plot idea could be exploring what would happen if Harry had a different upbringing, like being raised by the Malfoys.
