Well, some of the facts are related to the creativity it sparks. Fanfiction writers can create new characters that fit seamlessly into the Harry Potter universe. Also, it can be a great way to keep the Harry Potter fandom alive even years after the books were published. One more fact is that there are different genres within Harry Potter fanfiction, such as mystery, romance, and adventure. Some fanfictions might be set in different time periods within the wizarding world, like during the Founders' era at Hogwarts.
The concept of the Deathly Hallows is very unique. These three objects - the Elder Wand, the Resurrection Stone and the Invisibility Cloak - are central to the final part of the story. The Elder Wand is the most powerful wand, the Resurrection Stone can bring back the dead in a way, and the Invisibility Cloak has been passed down in the Potter family for generations. Harry's discovery and understanding of the Deathly Hallows play a crucial role in his final battle against Voldemort.
One random fact could be that in some fanfics, Neville Longbottom is often given a more heroic and central role. He might be shown as having even more powerful magic that was hidden during the original series. For example, he could be the key to a new spell or magical discovery that changes the course of Hogwarts.
Short dramas such as " Nine Supremes Mysterious Gate,"" Traversing Ancient Times to Be a Prince,"" 100,000 Years of Qi Training,"" Becoming the Hidden Richest Man's Favorite After a Flash Marriage,"" She Reborn After Five Years of Marriage," and " Flash Marriage Husband Is a Wealthy Family " all mentioned watching 1-100 episodes in one breath. Other than that, there were also short dramas such as " The Richest Man Returns to the Village,"" Fated to Meet You,"" A Fake Daughter Turns Over After Divorce,"" A Flash Marriage in Modern Times,"" Unparalleled Heavenly Dragon," and " Green Lotus Tribulation " that had about 100 episodes. These short plays could be watched on platforms such as Panlang Short Play Collection.
In Harry Potter fanfics, a random fact could be that the Marauder's Map has a hidden function. In some stories, it can not only show the people in Hogwarts but also predict where dangerous magic or dark creatures might appear. Some fanfics also play with the idea that the Sorting Hat has a mind of its own and can sometimes make mistakes on purpose. For instance, it might put a student in a house where it believes they will grow the most, even if it goes against the student's initial characteristics. There are also fanfics where Hagrid has a secret family of giants that he has to keep hidden from the wizarding world for various reasons.
One interesting fact is that goblins are excellent craftsmen. They create many of the magical items like swords and other precious artifacts in the wizarding world. For instance, Gryffindor's sword was made by goblins. Another fact is that they are not easily swayed and are very protective of their rights and possessions.
Ron Weasley, one of the family members, is a loyal friend to Harry Potter. Mrs. Weasley is a very protective mother figure who cares deeply for all her children and those she considers family.
One interesting fact is that J.K. Rowling based many of the magical creatures on real - world mythology. For example, the centaurs in the Forbidden Forest are inspired by Greek mythology. Another fact is that the Marauder's Map was created by Remus Lupin, Sirius Black, James Potter and Peter Pettigrew during their time at Hogwarts.
Some fanfictions depict Harry as having hidden magical abilities. He could have a special connection to an ancient magic that was dormant in the original series. For instance, he might be able to communicate with magical creatures on a deeper level, which is not shown in the main books. This adds an interesting layer to his character.
Fanfictions also change character facts by introducing new relationships. For instance, Ginny might be paired with a different character instead of Harry. This changes the whole dynamic of her character's story arc as it was presented in the official books. It also has a ripple effect on the other characters who interact with her in the fan - created story.
