Typically, Harry Potter himself is a main character. He is likely to be involved with the crystal in some way, whether it's trying to discover its powers or using it to fight against evil.
One interesting 'Harry Potter Crystal Fanfiction' story could be about a crystal that has magical powers to transport Harry to different wizarding realms. It might show him exploring new places and learning unique magics.
One common theme is the struggle for freedom. The characters are trapped in the crystal prison and they have to fight against the prison's constraints. Another theme is the discovery of hidden powers or secrets within the prison. There could also be themes related to friendship and loyalty as the characters try to rescue their friends from the prison.
In most 'Crystal Harry Potter fanfiction', Crystal is likely to be the main character. Since the fanfiction is named with her name in it, she usually takes center stage in the story. She could be a new addition to the Hogwarts crew, bringing her own unique abilities and personality to the mix.
There might be a 'Crystal Harry Potter fanfiction' where Crystal is a time - traveler. She comes from a future where the wizarding world is in chaos and she travels back in time to the days of Harry Potter. Her knowledge of future spells and dark magic techniques could be a game - changer in the battles against the Death Eaters. She could teach Harry and his allies new ways to defend themselves and counter the dark forces.
One interesting concept could be the combination of the magical world of Harry Potter with the kyber crystals from Star Wars. Maybe it involves using kyber crystals in a way that gives wizards new powers or enhances their existing magic. For example, a kyber crystal could be used to power a super - strong protective charm or a spell - casting device.
Another interesting fanfiction idea would be to have a character from The Dark Crystal, like Jen, end up at Hogwarts. Jen could learn about magic and how it differs from the magic in his own world. He might form friendships with the Hogwarts students and together they could face a common threat that somehow links the two universes, like a dark force that wants to take over both the wizarding world and the world of The Dark Crystal.
Sure. One popular 'Harry Potter Crystal Prison' fanfiction is 'The Escape from Crystal Prison' which has an exciting plot where Harry discovers a hidden power within the prison. Another one could be 'Crystal Prison Secrets' that delves into the backstories of the prisoners. There's also 'Inside the Crystal Prison' which focuses on the daily life and challenges within the prison in the Harry Potter universe.
Kira from The Dark Crystal could also be an interesting focus. If she were in the Harry Potter universe, her natural connection to nature and her strong will could make her a formidable ally. She could teach the Hogwarts students about the importance of nature in magic, which is something that is often overlooked in the wizarding world. Her skills with animals could also come in handy, like when dealing with magical creatures at Hogwarts.
One common theme is self - discovery. Just like Harry Potter in the original series, Crystal often goes through a journey of finding out who she really is and what her powers mean.
