It could be an original character created by the fanfiction writer. Maybe a young wizard or witch who has always felt like an outsider in their own family or at Hogwarts. They decide to set out on their own to find their true place in the wizarding world.
Another possibility is a half - blood or Muggle - born wizard who is trying to prove themselves in a world that is often divided by blood status. They are on a solo mission to show that regardless of their background, they can make a significant impact in the wizarding world. Along the way, they face discrimination but also find allies who believe in equality and help them on their journey.
It could be an original character created by the fanfic writer. This new character might be a transfer student to Hogwarts who doesn't quite fit in at first and thus often travels alone. They might have a mysterious past that makes them keep to themselves.
Hermione could be a 'lone traveler' in some fanfictions. She is smart and independent enough to embark on her own journey. Maybe she wants to research a very rare form of magic and has to go to a far - flung place all by herself.
It could be Neville Longbottom. After the Battle of Hogwarts, he might have decided to travel alone to study some rare plants in remote areas. He has always been an independent thinker, and this could be his way of furthering his knowledge and contributing to the wizarding world in his own way.
In Harry Potter fanfiction, 'the lone traveler' could refer to a character who embarks on a journey alone. This might be someone who has separated from their group for a specific purpose, like a wizard on a solo quest to find a lost magical artifact. It could also be a more metaphorical 'lone traveler', perhaps an outcast or a person with a unique destiny who has to face challenges without much support from others in the wizarding world.
One interesting aspect could be the unique adventures the lone traveler has in the wizarding world. Maybe they discover hidden places that are not mentioned in the original books, like a secret grove filled with magical creatures that have been long forgotten. They might also have different interactions with the existing characters. For example, they could form an unlikely friendship with a Hogwarts ghost and through that, learn some ancient secrets of the castle.
Well, some fanfictions depict a 'lone traveler' as a student who gets separated from the main group during a school trip or an adventure. This student then has to rely on their own skills and knowledge of magic to survive and find their way back. It often involves facing unknown magical creatures, solving puzzles, and growing as a wizard in the process.
How about Neville Longbottom? He could be the main character in a fanfiction set in the Chamber. Neville, who has always been underestimated, could show his true courage and strength. He might discover a hidden ability that helps him face the challenges in the Chamber, perhaps something related to his connection with plants, which could play a crucial role in defeating the Basilisk or whatever new threat is in the Chamber.
A lesser - known character like Ernie Macmillan from Hufflepuff could be the main character. As a prefect, he could bring out the unique qualities of Hufflepuff house. He might have to deal with issues like other houses underestimating Hufflepuff students. His story could focus on how he promotes the values of hard work, loyalty, and fairness within the house and the school as a whole.
Hermione could be a great main character. She's curious and intelligent, so she would be really interested in exploring the secrets of the diary. She could use her vast knowledge of magic to try and figure out how the diary works and what secrets it holds.
Harry Potter himself could be the main character as a revenant. Maybe he has some unresolved issues from his past, like his relationship with his parents. His revenant form could be on a journey to fully understand their sacrifice and his own place in the wizarding world's history.
