Another plot could revolve around a character who discovers a long - forgotten spell that can only be cast with the Elder Wand, leading to a series of adventures to master the spell and its implications. For example, this spell could have the power to restore lost magic in the wizarding world.
A possible plot is that the Elder Wand gets stolen and passed through different hands in the fanfiction. Each new owner experiences unique visions or powers associated with the wand, and as the main character tries to track it down, they uncover a conspiracy within the wizarding community that dates back centuries.
One idea could be exploring the origin of the Elder Wand in more detail. Maybe a story about the first wizard who crafted it and the magic used. Another could be a fanfic where Harry decides not to keep the Elder Wand but instead tries to find a way to destroy it permanently, facing many challenges along the way. And perhaps a plot where the Elder Wand has a mind of its own and tries to manipulate Harry into using it for dark purposes.
Imagine Harry travels back to the time of the Triwizard Tournament. With the Elder Wand, he could expose Barty Crouch Jr. much earlier. This would prevent Cedric's death and change the outcome of the tournament. It would also lead to a different dynamic in the wizarding world as Voldemort's plan to return would be thwarted much sooner.
One interesting plot idea could be a story where the Elder Wand has a hidden connection to the Goblet of Fire. Maybe the wand was used in the creation of the Goblet, and this connection is only discovered when a dark wizard tries to manipulate the Goblet's magic using the Elder Wand. The protagonist then has to figure out how to break this connection to stop the dark wizard's evil plan.
One interesting Elder Wand Harry Potter fanfiction could be 'The True Mastery of the Elder Wand'. It might explore a different path of how Harry really comes to fully understand and control the power of the Elder Wand, perhaps delving into ancient spells related to it.
One interesting 'Harry Potter Elder Wand' fanfic could be one where the Elder Wand has a sentience of its own and it tries to guide the wizard who wields it towards a different destiny than what is expected in the original series. It might lead the wizard to uncover secrets about the wand's true origin that were long forgotten.
Perhaps a plot where a group of students find a lost light wand in the Room of Requirement. This wand can emit a light that reveals hidden secrets in Hogwarts, leading them on an exciting adventure through secret passages.
Maybe the special wand was once owned by a very powerful and ancient wizard. The wand has memories of that wizard's great deeds and magic. As the new owner uses it, they start to have visions of those past events. This could add a lot of mystery and backstory to the fanfiction. The owner might have to learn from these visions to unlock the full potential of the wand.
A possible plot is that a character tries to create a wand that can counter the effects of the Dark Arts. They experiment with different materials and spells during the wand - crafting process. For example, they might use phoenix feathers from a different breed of phoenix or combine wood from a magically protected tree with a rare gemstone. As they progress, they face challenges from dark wizards who don't want this powerful anti - Dark Arts wand to be created. They also have to deal with the Ministry of Magic's regulations regarding new and untested wand - making methods.
A plot could be where the Phoenix wand is stolen and Harry has to go on a quest to get it back. He might have to face dark wizards who want to use the power of the phoenix feather for evil. Along the way, he discovers more about the true nature of his wand and the connection it has to the wizarding world as a whole.
A great plot for fanfiction could be a time - travel story. A wizard travels back in time to the era when the basilisk was first created or brought to Hogwarts. With the help of a special wand, they try to change the course of history regarding the basilisk. But every change they make has unforeseen consequences. For example, they might prevent the basilisk from being killed in the past, which then creates a new and more dangerous threat in the present. So, they have to find a way to fix what they've messed up while still dealing with the power of the basilisk and the wand.
