In some fanfictions, the sword could play a role in an alternate timeline. Maybe in this timeline, Voldemort got hold of the sword first. Then, it would be about how the characters try to retrieve it from him and what kind of dark magic he tries to use with it. It could also show how the sword resists his attempts to corrupt it because of its nature as the Sword of Evil's Bane.
There might be a fanfiction where the Sword of Evil's Bane is lost and Harry has to go on a quest to find it again. This could involve him traveling to places not explored in the original books, facing new enemies and making new allies. Along the way, he could learn more about the sword's true origin and the magic that forged it.
In some fanfictions, the sword might be used as a key to unlock a hidden chamber full of ancient magic. This chamber could hold secrets that could change the course of the wizarding world.
One interesting fanfic could be where the Sword of Gryffindor has a mind of its own and guides Harry in a different way. It might lead him to hidden secrets within Hogwarts that were previously unknown.
One great fanfiction could be one where the Sword of Evil's Bane has a mind of its own. It could lead Harry on a secret quest that wasn't part of the original books. Maybe it reveals hidden chambers in Hogwarts that were sealed by ancient magic related to the sword.
The sword is often a symbol of his rightful inheritance. It shows that he has a special connection to Gryffindor's legacy.
In some fanfiction, the Sword of Evil's Bane is linked to a prophecy. It's not just a weapon, but a key to fulfilling a greater destiny. This could involve Harry having to use the sword in a very specific way at a certain time and place to prevent a new dark force from emerging. The prophecy aspect gives the sword more significance and mystery.
Yes, in some fanfictions, Harry Potter is depicted as the heir of Gryffindor. It adds an interesting twist to the original story. The connection to the Gryffindor sword becomes more profound as it is often a symbol of Gryffindor's legacy. In these fanfictions, Harry might discover hidden powers or a deeper understanding of his destiny through this new identity.
One possible plot twist could be that the sword has a hidden power that only activates when in the hands of a true Gryffindor with a specific intention, like uniting all the houses against a new, unexpected dark force. Another could be that the sword was actually created with a part of Godric Gryffindor's soul, similar to a Horcrux but in a positive way, and it gives the wielder special insights into Gryffindor's thoughts and strategies.
Obviously, Harry Potter would likely be one of the main characters. He has a strong connection to the Sword of Gryffindor in the original series, so in the fanfic, he'd probably play a central role. Hermione Granger could also be a main character, using her intelligence to uncover secrets about the sword. And Ron Weasley might be there too, providing his loyalty and courage.
Often, it could be a plot device. For example, it might be the key to unlocking an ancient mystery in the RWBY world. Since the Sword of Gryffindor only appears to those worthy in the Harry Potter series, in RWBY fanfic, it could be that only a truly noble character can access it. And when they do, it causes a stir in the RWBY world as it's an unknown and extremely powerful object.
A great one might be 'The Sword's Legacy'. In this fanfic, the Sword of Gryffindor passes on a special kind of magic to Neville Longbottom. Neville uses this new - found power to protect Hogwarts during a time when Harry is away on a secret mission. It's really exciting to see Neville in a new role with the help of the sword.
