Well, he could be a new student at Hogwarts who's a bit older than the others. Since he has his unique way of seeing things, he might be sorted into Ravenclaw for his intelligence and ability to analyze. In the fanfic, he could start investigating some strange happenings around the school that seem related to the Forbidden Forest, using his profiling skills to figure out if there's a 'human' or rather a wizard or magical creature behind it all.
Perhaps Will Graham is a wizard who was raised in the Muggle world without knowing his true heritage. When he discovers he's a wizard and comes to Hogwarts, he struggles to fit in. His skills in understanding human (or in this case, wizard) behavior make him an outcast as the other students are more focused on spells and potions. But then, he uses his knowledge to solve a mystery that's been plaguing the school, like a series of unexplained disappearances that are linked to a hidden chamber.
A possible plot could be that Will Graham is brought to Hogwarts by Dumbledore to help deal with a new kind of threat. This threat could be a dark wizard who's using psychological warfare on the students. Will Graham's profiling skills would be put to the test as he tries to figure out the motives and methods of this dark wizard. He might start by interviewing students who have had strange encounters and use his knowledge of human nature to piece together the puzzle.
Not usually. Will Graham is not a common character in Harry Potter fanfic.
I'm not sure. You might have to do a detailed search on Archive of Our Own to find out.
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.
In fanfiction, Mother Earth could be a hidden force that has been dormant for a long time. But due to some great imbalance in the wizarding world, she starts to awaken. Harry Potter might be the one to first sense her presence, maybe through a strange dream where he sees the earth itself calling out for help. Then, as the story progresses, he discovers that Mother Earth can communicate with certain wizards, and she imparts her wisdom to him to help him fight against the forces that are causing the imbalance, such as over - use of dark magic that is harming the natural world.
One way could be that the Infinity Stones are hidden artifacts in the wizarding world. Maybe they were created by an ancient and extremely powerful wizard long ago, and their powers are so great that they are feared and thus hidden. For example, the Time Stone could be related to time - turners, but with much more powerful time - manipulating abilities.
Perhaps the Chaos Emeralds are hidden in different wizarding schools around the world, and in the fanfiction, a quest is set up for Harry Potter and his friends to find them all. Each emerald could grant a different ability, such as the power to control the elements, which could be used against the rising dark forces in the wizarding world.
One way could be by having the house - elves start a revolution. They are an oppressed group in the wizarding world, similar to the working class in a capitalist society. They could demand equal rights, fair treatment, and an end to their enslavement, much like the goals of a communist revolution.
It can add by exploring the uncharted emotional territories of the characters. The original books didn't fully delve into every character's fear in extreme detail. Fanfic can do that. For instance, it can show how Ginny Weasley overcomes her fear of being possessed by Voldemort again.
It could be a reference to a certain character's look or attitude. Maybe there's a new character in the fanfic who has a steely gaze, and the author describes it as 'blue steel' to give a sense of mystery and cold determination. This character could be an ally or an enemy to Harry and his friends, adding a new layer of intrigue to the story.
