Well, it could be about Harry using his skills and magic knowledge to custom - create a super - powered Firebolt. Maybe he adds some unique enchantments to it for speed or stealth.
Harry is the main one, but other characters could be involved in different ways. Neville could accidentally stumble upon Harry's secret project and, in his clumsy but kind - hearted way, end up helping. Luna Lovegood might offer some out - of - the - box ideas with her unique perspective on magic. And Dumbledore, with his vast knowledge and wisdom, could be a guiding figure in the background, giving Harry some cryptic advice that helps him in the creation of the Firebolt.
One possible reason could be for speed. The Firebolt is known for its incredible speed in the Harry Potter series, and Harry might need it for faster travel between Hogwarts and other places, or for Quidditch matches to outrun his opponents more easily.
Maybe he loves the idea of the Firebolt in the fanfiction. It could be that the stories expand on his experiences with the Firebolt in a really exciting way.
The fanfiction might include some amazing races or battles on the Firebolt that Harry is really into. It could also show the Firebolt in a different time or place, like in a magical tournament in a far - off land. Plus, the fanfiction could give more backstory to the Firebolt, such as who made it and why it's so special. All these elements combined could be what makes it so appealing to Harry.
There's a fanfic where Voldemort curses the Firebolt, and Harry has to remake it using ancient magic and rare materials. The process is full of challenges and discoveries.
One idea could be that Harry creates a school for magical creatures. He realizes that there are so many unique and often misunderstood creatures in the wizarding world, and he wants to give them a place to learn and grow. This school could teach them how to interact with wizards in a positive way, as well as develop their own magical abilities.
Maybe it's a story where a powerful curse affects the Firebolt, and Harry has to find a way to remake it to regain his edge in Quidditch and face other magical challenges. The focus could be on his determination and ingenuity.
In this fanfiction, Harry might also include some of the Hogwarts ghosts in his army. After all, they have a long - standing relationship with the school. Peeves, for example, could be a wild card in the army. He can cause chaos among the enemies. And some of the older students who have a strong sense of justice, like Cedric Diggory's friends, could also be part of it.
The exploration of the wizarding world is a major part. When Harry creates magic, it can open up new areas of the wizarding world to be explored. It could be a hidden chamber where the new magic was born or a new group of wizards who are interested in his creations. This allows the author to expand on the already rich Harry Potter universe and take the readers on a new and exciting journey.
