The fanfiction could start with Harry having a strange dream about a glowing sword. Then, one day, he stumbles upon a mysterious object in the Forbidden Forest that turns out to be a lightsaber. He soon realizes that he has a natural affinity for it. He starts training with it secretly, and as he gets better, he uses it to defend Hogwarts against not only Voldemort's forces but also other dark creatures that are attracted to the power of the lightsaber.
Well, perhaps Harry discovers an ancient magic that allows him to wield a lightsaber. He could use it to fight Voldemort in a more unique way, combining the magic of the wizarding world with the power of the lightsaber. Maybe he has to go on a quest to learn how to master it fully.
The plot could start with Harry finding an ancient Jedi artifact during one of his adventures. This leads him to become curious about lightsabers. He then uses his magic knowledge to try and replicate it. Along the way, he might face opposition from some in the wizarding world who think it's too dangerous or against wizarding traditions. But Harry, being the hero he is, persists. Eventually, he creates a lightsaber and uses it to defeat a new, powerful dark wizard who has emerged, using both his wizarding skills and his new lightsaber skills.
Well, perhaps Harry Potter discovers some ancient magic that allows him to combine the wizarding world's technology with that of the Star Wars universe. He might use his knowledge of spells to power the lightsaber in a unique way, like using the Lumos spell to create the blade instead of the traditional kyber crystal. He could then face off against Voldemort with this new weapon, creating a whole new dynamic in their battles.
Obviously, Voldemort could still be the main antagonist. He would be intrigued and threatened by Harry's new power, the lightsaber. Also, some Death Eaters might team up with dark wizards from other lands who are also after the power of the lightsaber.
Well, in theory, it could. Fanfics often like to blend different fictional universes. However, in the official Harry Potter lore, there are no lightsabers. But in a fanfic, an author could come up with some creative magic or a cross - universe event that brings lightsabers into the wizarding world. Maybe a powerful wizard discovers a way to create a weapon similar to a lightsaber using magic and some rare materials.
I think Hermione would be the most likely. She's very intelligent and a quick learner. She would study all the available information about lightsabers, probably find some ancient texts in the library about similar weapons. With her determination and knowledge - seeking nature, she'd be able to master the basic techniques of lightsaber handling in no time.
In this fanfiction, Harry could potentially use the lightsaber to his advantage in battles against dark wizards. The lightsaber's unique cutting ability could be a great asset. He might also face challenges like having to keep it hidden from the Ministry of Magic which doesn't recognize non - magical weapons. And there could be a whole plot about where the lightsaber came from, like if it was brought to the wizarding world by a mysterious traveler from another dimension.
Maybe an old wizard who has been secretly studying the combination of different magical universes for years. This wizard could have made some initial attempts at building a lightsaber - like weapon in the past and can share his experiences and mistakes with Harry. He would teach Harry about the balance between the light and dark side of this new form of magic, just like the Jedi teachings in Star Wars.
The plot could involve Harry finding an old, enchanted bow in the Forbidden Forest. He discovers he has a natural talent for archery and starts training in secret. As he gets better, he uses his archery skills to help during the Triwizard Tournament, hitting targets that others can't reach with magic, and thus winning challenges in a unique way.
One possible plot could be that Harry Potter somehow gets transported to the Halo universe. He has to learn to use Master Chief's weapons and fight alongside him against the Covenant. Meanwhile, he also tries to figure out how to use his magic in this new high - tech world.
Well, it could be about Harry using his skills and influence in the wizarding world to reform the political system. Maybe he starts by uniting different magical communities within Hogwarts, like the houses, and then expands it to the whole wizarding society.
