Another possibility is a magic - infused amulet that allows Harry to access different forms of magic. It might give him the ability to use ancient spells or magics that were long forgotten. This unique magic focus could also have a mind of its own and guide Harry on his magical journey, presenting him with challenges and opportunities to grow as a wizard.
Perhaps it's a magical crystal that enhances his ability to communicate with magical creatures. This would be quite unique as it would give him an edge in dealing with things like thestrals or unicorns, and open up new storylines in the fanfiction. Harry could use this crystal to understand their needs and gain their help in various situations.
He becomes more confident. With the unique magic focus, he has something that sets him apart. This newfound power or ability makes him less self - doubting and more assertive in his actions.
In such a fanfiction, Harry might discover ancient spells that give him an edge in battles. For example, he could learn old defensive magic that can protect Hogwarts in a more powerful way than the existing spells. He might also use old magic to communicate with long - lost magical creatures that hold secrets of the wizarding world.
It could be an older relative who was thought to be dead but actually has been living in seclusion, waiting for the right time to teach Harry about their family magic. This relative might have a vast knowledge of the family's magical traditions and spells.
Well, it could be that Harry has an encounter with an Egyptian wizard who decides to teach him their unique brand of magic. This magic might involve things like controlling the sands or communicating with mummies. Through his learning, he gains new powers and uses them to face his enemies in a different way than before.
Maybe it could be an ancient magical being like a centaur. Centaurs are known for their knowledge of the stars and ancient magic. They might take Harry under their wing and teach him old magic that has been passed down through their generations.
It could be Dumbledore, even if he's passed away. His portrait or some kind of magical remnant of him might still be able to guide Harry in learning new magic.
Overcoming limitations is also a theme. Since wandless magic is not the norm in the wizarding world as presented in the original books, Harry has to break through the traditional thinking. He has to deal with the doubts of others and his own insecurities. In some fanfics, he even has to face opposition from the Ministry of Magic who are wary of this unregulated form of magic.
It might be a story where Harry delves into the family magic in order to solve some sort of mystery. For example, he could be looking for a way to defeat a new dark force and realizes that the family magic holds the key. He could learn new forms of magic related to protection or divination that are unique to his family.
Hermione could be a strong ally. She's smart and could help Harry research more about battle magic. Ron too, with his loyalty and courage, would be by Harry's side.
Obviously, Harry Potter is the main character as the title implies he is the one learning magic early. But there could also be Hermione and Ron. Hermione might be intrigued by Harry's newfound knowledge and Ron could be both a bit jealous and in awe of Harry's early magical abilities.
