One plot idea could be that the Wonder Wand has a mind of its own and leads Harry on a quest to discover its true origin. It might take him to places not known in the original series, like a hidden wizarding enclave where the wand was first crafted.
Perhaps a plot where the Wonder Wand starts to malfunction and gives out strange spells. Harry then has to seek the help of an ancient wizard who has long been in seclusion. During this journey, he discovers new aspects of magic and also uncovers secrets about his own family's connection to the wand.
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.
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.
In some fanfiction, the wand with the dragon fang could be a key to an ancient wizarding treasure. But it's protected by powerful spells. The wizard has to figure out how to unlock the wand's full potential in order to access the treasure and along the way, he meets many challenges and makes new allies.
One idea could be to write about a wand that has a mind of its own and causes chaos for its owner. For example, it might cast spells at inappropriate times or choose to work only for certain types of magic that the owner isn't familiar with.
One idea could be a fanfic where a character discovers a long - lost wand with a special power. For example, a wand that can open portals to different magical realms. The character then has to figure out how to use this power without getting into too much trouble with the Ministry of Magic.
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.
