One way is to have the characters work towards a more inclusive wizarding world. For example, Hermione could start a campaign to admit more Muggle - born students into Hogwarts without discrimination. This would lead to a better future as it breaks down the barriers between pure - bloods and non - pure - bloods, creating a more harmonious and diverse community within the wizarding world.
Perhaps in the fanfiction, Neville discovers a new form of magic that can heal the damage done to the Forbidden Forest during the battles. He shares this knowledge with others, and together they restore the forest to its former glory. This not only helps the magical creatures that live there but also has a positive impact on the overall environment of the wizarding world, contributing to a better future.
He could meet his future children, if he has any. They would likely be powerful wizards or witches with their own adventures. Also, he might run into the future versions of Hermione and Ron. They would probably be in important positions in the wizarding world, like Hermione might be a headmistress at Hogwarts or something.
He might meet the future versions of his friends like Hermione and Ron. Their children or grandchildren could be there, and they might have different personalities and magical skills compared to their predecessors.
He might be shocked. In fanfiction, the future could be full of strange twists. For example, if his friends' children are involved in some wild adventures that are very different from what he expects. He would probably be confused at first, then curious to understand how things got to that point.
He'd first have to get used to the new technology. If there are new magical devices, he'd need to learn how to use them. For instance, if there are advanced wands with extra functions, it would take him some time to figure them out.
Harry would rely on his basic values. His loyalty and courage would still be his strong suits. He might join a group of young wizards who are working on some noble cause in the future magic world. Through interacting with them, he'd gradually understand the new rules and customs. For example, if there are new dueling regulations, he'd learn them in the process of joining friendly duels.
'Better in the dark' in Harry Potter fanfiction could refer to a lot of things. It might be a story concept where certain events, relationships, or magical elements are better explored or presented in a darker, more mysterious setting. For example, it could be about a secret society within Hogwarts that operates in the shadows and their actions are better understood when the full scope of their 'dark' activities are revealed.
In this fanfiction, Harry might see a world where magic has evolved in unexpected ways. For example, there could be new spells that are far more powerful and complex than the ones he knew. He could also find that Hogwarts has changed, perhaps with new buildings or different teaching methods. And maybe he would encounter descendants of his friends, who have their own unique stories to tell.
There's also 'Harry Potter and the Future's Secrets'. Here, Harry starts seeing the future after a strange encounter in the Forbidden Forest. The story focuses on how he uses these future - seeing moments to protect his friends and outwit his enemies. It has some great plot twists and really delves into the relationships between the characters in the face of this new power.
