Well, many types of weapons are made. Wands, for sure, but with new and interesting features. For example, some wands in fanfiction might be made to work better for a specific type of magic, like a wand that is excellent for transfiguration but not so good for defensive spells. There are also enchanted jewelry pieces that can be used as weapons, like a necklace that can emit a force field when threatened. And don't forget about magical staves that can be used to channel large amounts of magic at once, which are different from wands in terms of power and usage.
It could be about a doll maker within the Harry Potter universe. Maybe this doll maker creates magical dolls that have some sort of significance in the wizarding world, like they could be used for spells or they hold secrets. It might also involve the main characters from Harry Potter interacting with this doll maker and the dolls they create.
It could be about creating a story where there is some kind of annihilation in the Harry Potter universe. Maybe it involves creating a scenario where a powerful force is trying to annihilate the wizarding world, or perhaps a character with the power of 'annihilation' making their mark in the story.
One possible fanfiction could be about a female Harry Potter who discovers her talent for toy making in the wizarding world. Maybe she creates magical toys that can help young witches and wizards with their studies, like a self - teaching quill that writes out spells correctly. This could lead to all sorts of adventures as other characters try to either steal her ideas or collaborate with her.
The wand maker's character can be developed by showing their passion for their work. For example, they could be shown spending long hours in their workshop, carefully selecting and carving each wand. This would show their dedication.
A 'weapon maker novel' could be about an individual's journey in becoming a weapon maker. It could explore their motivations, like a desire for power, or a need to protect their homeland. The story might also include their encounters with different materials, secrets of forging, and the relationships they build with those who commission their weapons or use them in combat.
Perhaps Harry discovers a hidden talent for doll making during his time at Hogwarts. He could use magic to create dolls that come to life and help him in his adventures, like acting as spies or messengers.
Since it's a fanfiction based on Harry Potter, Harry Potter himself might be one of the main characters. He could be the one to stumble upon the doll maker's workshop. Hermione would also be a likely main character as she's always curious and would want to learn about the doll maker's craft. Ron could be there too, providing his usual comical and sometimes skeptical view of things.
It's hard to say without reading it, but it could be Harry Potter himself. He might be trying to stop the annihilation maker from causing destruction. Or it could be a new character created by the fanfic author who has a special connection to the annihilation maker.
It could be a young, talented wizard who has a natural gift for ring - making. Maybe Harry Potter himself might be involved, either as a customer or an inspiration for the ring - maker.
