Perhaps the grey faction would focus on magic that is neither clearly good nor bad. Harry could start exploring grey areas of magic that have been long forgotten or shunned. He might team up with some characters who were previously on the fringes, like those who practice magic that is not strictly legal but not necessarily evil. The fanfiction could then be about their journey to gain acceptance for this new way of thinking within the wizarding community.
Luna Lovegood might also be a likely candidate. She has a unique perspective on the wizarding world and is not bound by the traditional views. Luna could offer her creativity and her ability to see things that others overlook. Her friendship with Harry could easily lead her to support his new grey faction and contribute in her own strange but wonderful way.
A possible plot could be that a Harry Potter character discovers an ancient magic that has similarities to the Force. They then start to develop abilities and a moral code similar to Grey Jedi. They might face opposition from both the wizarding world, which is used to the traditional light and dark magic, and some dark forces that see this new power as a threat.
He could start a business in the area of defensive magic. Given his own experiences with Voldemort and the Dark Arts, Harry is well - equipped to teach others how to defend themselves. He could open a store that sells all kinds of defensive magic items, from protective cloaks to anti - Dark Arts spells in a book form. He could also offer personal training sessions where he teaches people how to use Patronuses and other powerful defensive spells.
Well, perhaps Harry starts a factory to produce anti - dark magic devices. He uses his knowledge of the dark arts and his experience fighting Voldemort. He could bring in Hermione to help with the research side of things, and Ron to manage the day - to - day operations. The factory might be a target for dark wizards who don't want such devices to be widely available.
One possible plot could be that Harry uses his skills from fighting Voldemort and his knowledge of the wizarding world to form a sellsword company. He might recruit some of his old Hogwarts friends like Ron and Hermione. They could offer protection services to wizarding families or even to magical creatures. For example, they could protect a family of centaurs from poachers. The company could also get involved in solving magical disputes in a more hands - on way than the Ministry of Magic usually does.
In this fanfiction plot, a powerful dark force is threatening both the world of mutants and the wizarding world. Harry Potter and Jean Grey are chosen by their respective communities to investigate the source of this threat. As they work together, they discover that their powers complement each other in unexpected ways. Their relationship grows from friendship to love during their adventures. They decide to get married as a sign of their commitment not only to each other but also to the joint fight against the dark force. Their marriage then becomes a symbol of hope for the combined forces of wizards and mutants, and they lead the charge to defeat the evil that looms over both their worlds.
He could fund magical education reforms. For example, he might establish new schools or improve the existing ones. He could also invest in research on new spells and magical artifacts. This would not only benefit the wizarding community but also give him more influence.
The plot of such a fanfiction could be really intricate. Imagine Harry Potter suddenly realizing that he can sense a different kind of energy, the Force. He starts to explore this new power secretly, fearing how others in the wizarding world would react. As a grey Jedi, he has the freedom to use the Force in ways that are not strictly light or dark. He could use his powers to enhance his magic, for example, using Force - enhanced speed to be quicker in Quidditch. He would then get involved in a conflict that requires both his wizarding skills and his new Jedi abilities. Maybe Voldemort has some connection to a dark side Force user, and Harry has to use his grey Jedi knowledge to defeat this new threat. Along the way, he would have to make difficult choices about how to use his powers, and this could lead to some tense moments with his friends and mentors in the wizarding world.
Well, he might bring his unique magical skills from the wizarding world of Hogwarts. His ability to use spells like Expecto Patronum could be a great asset against the darkspawn that the Grey Wardens fight. Maybe he'd form new friendships with the Wardens and learn their ways of combat and survival.
He could meet a brilliant but eccentric teacher. This teacher might be an expert in a very rare branch of magic that Harry has never heard of before. The teacher could take Harry under their wing and teach him things that Dumbledore or the other Hogwarts teachers never did.
