In this fanfic, the knife could be a symbol of power or danger. If it has some dark magic associated with it, perhaps it was hidden away in Egypt for a reason. Bill and Charlie, being brave Weasleys, might get caught up in a struggle to either keep it out of the wrong hands or use it to defeat an evil force that has something to do with Egypt. It could also be a family heirloom that has a connection to their Egyptian heritage that they didn't know about until they delved deeper into their family's past.
The knife could be a part of an ancient ritual. The Weasley family, known for their interest in magic and history, might discover that the knife is needed for a long - forgotten Egyptian magic ritual. Maybe they need to use it to unlock a hidden chamber full of powerful magic items. Bill could be the one researching the ritual while Charlie is the one who actually has to perform it with the knife.
In a fanfic scenario, perhaps Bill and Charlie are on a mission in Egypt. The knife could be a magical or important artifact they are seeking. As for the honey, it could be part of a riddle or a key ingredient in a potion they need to make. Fanfic allows for these strange and wonderful combinations of elements.
In an Egypt - themed fanfic, Bill could be a pharaoh and Charlie his trusted advisor. The knife could be a ceremonial weapon used in rituals. The honey could be an offering to the gods. It's a simple yet interesting way to incorporate these elements into the fanfic.
The theme of self - discovery can also be found in many Bill and Charlie Weasley fanfics. As they go through different experiences, they learn more about themselves, their strengths and weaknesses. Additionally, magic and its exploration is a common theme. Given their magical abilities and interests, fanfics might have them discover new spells or magical artifacts during their adventures, which in turn helps them grow as wizards.
A really interesting fanfic is 'Charlie's Dragon and Bill's Curse'. In this story, Charlie's work with dragons intersects with a mysterious curse that Bill is dealing with. It's full of action and mystery. There's also 'Bill and Charlie: Hogwarts Years' which gives a new perspective on their time at Hogwarts, showing their growth and the pranks they played together.
Charlie is also great. His love for magical creatures makes for some really interesting plotlines. He could introduce a whole new world of creatures into the fanfiction that the others have to interact with.
One great 'Bill Weasley fanfic' is 'Bill's Adventure Beyond Hogwarts'. It really delves into his post - Hogwarts life and his work with Gringotts. The author does a wonderful job of portraying Bill's character, his loyalty to his family and his love for adventure.
One interesting fanfiction could be about their adventures together in the Forbidden Forest. Maybe they discover a hidden magical creature that no one has ever seen before. They would have to use their combined skills and knowledge to figure out how to deal with it.
One possible plot could be that Bill Weasley has a special magical ability in his fingers. For example, his fingers can detect dark magic. Harry Potter, in his quest to defeat Voldemort, comes across some strange dark magic residue. Bill uses his finger - based ability to analyze it and they work together to figure out a way to counter the dark magic.
Yes, there might be some fanfictions with this theme that are family - friendly. Some authors may focus on the emotional and platonic aspects of their relationship rather than any inappropriate content. For example, they could write about Charlie and Hermione sharing adventures or having deep conversations that build a strong friendship or a budding romance in a very innocent way.
