The Elder Wand could be used to control the flames of the Goblet of Fire. For example, a character might use the wand to make the Goblet's flames do specific things like form shapes or spell out messages. This could be used as a form of communication during the Triwizard Tournament or as a way to unlock a hidden mystery within the Goblet.
Well, in a new and unexpected way, the Goblet of Fire could have the ability to choose the rightful owner of the Elder Wand. In the original story, the Elder Wand's ownership is transferred through combat, but in this fanfiction, the Goblet could be enchanted to recognize the most worthy wizard or witch to wield the Elder Wand. This would completely change the dynamics of power and ownership in the wizarding world and lead to a whole new set of adventures and conflicts as different characters vie for the chance to be recognized by the Goblet for the Elder Wand.
He could keep it by disguising it as an ordinary object. For example, he could use a transfiguration spell to turn it into a simple stick or a quill. That way, no one would suspect it was the Elder Wand.
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.
The fusion could be shown as a chaotic yet beautiful event. Sparks could fly from the wands as they touch, and the magic within them could seem to fight at first, like two different forces trying to assert dominance. But then, as they start to meld, the chaos gives way to harmony. The colors of the magic, say the warm red - gold of Harry's wand and the cold, steely grey of the Elder Wand, could blend into a new, unique color. And the resulting fused wand would look as if it was crafted by the most skilled wand - maker, with an otherworldly beauty and an aura of great power.
A character who is a descendant of the original maker of the Elder Wand. They might have an innate connection to the wand and possess knowledge about its secrets that no one else does.
Daphne could be a researcher of ancient magical artifacts and she comes across some information about the Elder Wand that she shares with Harry. For instance, she might have found a dusty old book in the library that details a secret property of the wand. This information could be crucial for Harry in his journey regarding the wand.
Maybe it's an old wandmaker from a far - off land. This wandmaker has been crafting wands for centuries and has a unique intuition about which wands are meant for which wizards. He sees something special in Harry and presents him with a new wand.
A new character could be an ancient wizard who was once a rival of the wizard who first owned the Elder Wand. This wizard has been in hiding for centuries but now resurfaces because of the Elder Wand's newfound prominence. Another interesting character could be a young witch who has a natural affinity for the Elder Wand and is drawn to it, even though she doesn't fully understand why. She could be a wildcard character, not clearly on Harry's side or the side of those who would misuse the wand.
Well, it might be that the Goblet of Fire has been corrupted in the fanfiction. It could be causing chaos in the Triwizard Tournament, endangering the lives of the students more than it should. Harry, being the hero, takes it upon himself to destroy it to restore order. For example, if it starts spawning dangerous and unfair tasks that are clearly not part of the original tournament's design.
The Elder Wand is a key plot device. Its changing ownership creates a lot of tension and action. For example, when Voldemort tries to gain control of it, it sets off a chain of events that leads to many battles and confrontations.
Wand spirits often interact with their wizards through the magic they perform. When a wizard casts a spell, the wand spirit can subtly influence how the magic is channeled. It's like a silent partner in the magic - making process.
