One reason could be to escape the constant scrutiny and expectations that come with being 'The Boy Who Lived' in Magical Britain. He might feel suffocated by the fame and the never - ending battles against the Dark Arts in his homeland. Another reason could be a quest for new magical knowledge. Magical Britain has its own set of magical teachings, but there could be other, more esoteric forms of magic in other parts of the world that he wants to explore. Also, he might be running away from a personal tragedy or a broken relationship. Maybe a falling - out with his friends or a loss of someone dear to him makes him want to start anew elsewhere.
The theme of breaking free from expectations is quite common. In Magical Britain, Harry has so many expectations placed on him because of his status as 'The Boy Who Lived'. When he leaves, he can be his own person and not be defined by those labels. Also, the exploration of different magical cultures is a big theme. He gets to see how magic is practiced in other parts of the world, which is really fascinating.
Well, it could signify a very different take on the Harry Potter universe. Maybe in this fanfiction, the author wants to explore the idea of Harry Potter causing the downfall of the magical society in Britain for various reasons, like a radical change in his character or some extreme circumstances.
There could be personal consequences for Harry as well. He might face opposition and even threats from those who want to protect the status quo in Magical Britain. His friends and family could also be affected, either by being targeted or by being caught in the middle of the conflict between Harry and the establishment. However, this could also make him more determined to fight for what he believes is right.
One possible reason could be the corrupt system in Magical Britain. In some fanfictions, the Ministry of Magic is shown as being full of bureaucrats who are more concerned with maintaining power and the status quo rather than doing what's right. For example, they might be slow to respond to real threats or they could be discriminatory towards certain groups, like Muggle - borns. Harry, having grown up in a non - magical world and having a sense of justice, would naturally despise such a system.
Obviously, Harry Potter is the main character as he is the King of Magical Britain in this fanfiction. His friends like Hermione Granger and Ron Weasley are also likely to be important characters. They would probably be his advisors or help him in his various endeavors.
There's 'Harry Potter: Beyond the British Isles'. Here, Harry's departure from Magical Britain is due to his search for a real home. He has always felt like an outsider there. As he leaves, he embarks on a journey full of self - discovery and adventure, meeting all sorts of unique magical creatures and characters in far - flung places.
Well, perhaps in this fanfiction, Harry Potter accidentally casts a spell that has a domino effect on the magical economy of Britain. For example, he might mess up a powerful charm related to the wizarding currency, leading to a rapid devaluation. Or maybe he uncovers some dark secret about the Ministry of Magic's financial management that causes a mass panic and economic collapse.
One interesting scenario could be Harry Potter starting a new life in the Muggle world and using his magical skills in secret to help people. For example, he might use magic to heal the sick in a Muggle hospital without them knowing. Another could be him exploring different magical cultures outside of Britain, like those in Asia or Africa that are not much explored in the original books. He could learn new spells and magical techniques and bring them back to the wizarding world in the future.
Hermione could accompany him. She's always been by his side and would likely follow him out of loyalty and a thirst for new knowledge. Together, they could explore new magical theories in different parts of the world. Another possibility is Hagrid. He has a soft spot for Harry and might want to protect him on his journey. He could introduce Harry to different magical creatures in other countries.
