Perhaps they would go to Egypt. Egypt has a deep connection to ancient magic. There are countless ancient tombs and artifacts that hold powerful magic. Harry and Hermione might be drawn there to study the old magic, learn about the magic of the pharaohs, and uncover secrets that could help the wizarding world as a whole.
One possibility is America. The American wizarding world is quite different from England's. There are different magical creatures, different magical laws, and a whole new set of challenges and opportunities. They could end up in New York or Salem, places with significant magical presences in the American wizarding community.
They might go to France. France has a rich wizarding history and a beautiful wizarding community. The Beauxbatons Academy is there, and they could explore the magic related to it. There are also magical places like the French Ministry of Magic which would be interesting for them to visit.
One reason could be to escape the trauma of the war. They've been through so much in England, and leaving gives them a chance to heal in a new environment.
One reason could be to escape the danger and dark forces that still lurk in England even after the main battle. They might feel that leaving is the only way to start anew and be truly safe. Maybe they want to explore other magical cultures around the world and learn more about magic that is different from what they've known in England.
One interesting fanfic could be 'A New Start'. In it, Harry and Hermione leave England due to the constant reminders of the war and a desire for a fresh start. They travel to a small, idyllic village in France where they begin to explore new forms of magic and build a life away from the prying eyes of the British wizarding world.
There's a fanfic titled 'Beyond England's Borders' which details their journey of leaving England. It delves into how they deal with the challenges of leaving their home country, like leaving behind friends and family, while also facing new magical threats and adventures. In this story, they head to France first and thenventure further into Eastern Europe, exploring different magical cultures along the way.
Maybe he's tired of the spotlight in England. In some fanfictions, he could be seeking a new start away from the prying eyes and the constant media attention that comes with being in England.
One reason could be to explore the wizarding world outside of England. There are many magical places they might be interested in, like the wizarding communities in France or America. They could be on a mission to learn more about different magical cultures and bring back new knowledge to England.
They could encounter new magical creatures. For example, in other parts of the world, there might be undiscovered or rare magical beasts that they have never seen before in England. This would be a whole new experience for them to learn about these creatures and how to interact with them.
Perhaps they would head to America. In the wizarding world of America, there are different magical institutions and a large expanse of land where they could start anew. They might be drawn to the Ilvermorny School of Witchcraft and Wizardry area, to interact with new wizards and witches and learn from a different magical education system. Also, the American magical community might not be as involved in the affairs of the English wizarding world, providing them with some anonymity.
They could go to France. France has a rich magical history and a large wizarding community. It would be a place where they could blend in and also learn new magical techniques. The Beauxbatons Academy of Magic is there, which could offer a different educational environment if they had children.
