The wizarding world would be far more primitive. There might not be organized schools like Hogwarts. Instead, magic would be passed down through families or small groups. Harry would be part of a more superstitious society where magic and non - magic were not as clearly divided as in modern times. His role could be to bridge the gap between different magical factions, as his unique powers might be seen as a way to unify the various groups in the face of common threats like marauding magical beasts.
If Harry was born in ancient times, the concept of good and evil magic might be more fluid. There was no clear - cut Dark Arts as we know it today. Magic was used for survival and power struggles within the wizarding community. Harry would grow up in a world where magic was a tool for hunting, building, and protecting. His fight against the 'dark side' would not be against a single Dark Lord like Voldemort, but rather against the chaos and anarchy that threatened the stability of the wizarding world. His journey would be about bringing order and a new understanding of magic to a world that was still in its infancy in terms of magical ethics and knowledge.
One way could be through the use of magic in a Chinese cultural context. For example, potions might be made with traditional Chinese herbs instead of the usual European ones. Spells could be influenced by Chinese incantations or concepts like Qi. And perhaps the Hogwarts houses could have some Chinese elements incorporated, like the values of Confucianism being reflected in the sorting of students.
It expands the wizarding world by introducing new magical creatures. Fanfiction often includes creatures that were not in the original books, which can inhabit new areas of the wizarding world. For example, some fanfictions might have underwater magical creatures with their own unique magics. This forces the wizards in the story to interact with different ecosystems. Another way is through new forms of magic education. Instead of just Hogwarts - style teaching, fanfiction can show different schools or methods of teaching magic, like a school that focuses solely on defensive magic and has its own set of spells and techniques.
Harry would need to learn about the different magical laws in America. For instance, the regulations regarding magical creatures might be stricter or more lenient compared to the UK. He might also have to get used to the different currency used in the American wizarding economy.
The wizarding world would likely be very different. Magic might have evolved in ways that are unrecognizable. Harry, being 500 years old, would have witnessed these changes. There could be new forms of magic, new magical creatures, and different social structures. For example, the Ministry of Magic might have transformed into something entirely new, perhaps more of a democratic council where all magical beings have a say.
Well, Harry's immortality would bring about a great change in the wizarding world. Since he can't die, he could be a source of hope for a very long time. He might inspire new generations of wizards to be braver. Also, the way magic is used and perceived could change. For instance, people might study his immortality to find ways to extend life in general. And his influence on the fight against dark forces would be continuous, not just a one - time deal like in the original story.
It might have a more modern exterior. While shops in the wizarding world in England often have a traditional and somewhat old - fashioned look, in New York, his shop could blend in with the modern architecture a bit more.
The Order of the Phoenix would immediately spring into action. They would start searching for Harry using all their magical resources, including spells like the Tracking Charm. Dumbledore would likely be at the forefront, using his vast knowledge and connections to try and figure out where Loki has taken Harry.
The wizarding world would likely be plunged into a state of despair. Harry was seen as the 'Chosen One' to defeat Voldemort, so without him, there would be a sense of hopelessness. Voldemort would probably have free rein to impose his dark rule without much opposition at first.
They could fit in as strange visitors from another dimension. The wizards would be both curious and cautious about them. Maybe the Guardians are there to trade some unique galactic items for magical artifacts.
The wizarding world would be in an uproar. Phylacteries are associated with dark magic. Harry is seen as a hero, and for him to create a phylactery would shatter the image. The Ministry of Magic would likely brand him as a dark wizard or at least someone who has strayed too far from the light. His friends would be divided. Some might try to defend him, believing there was a good reason, while others would be horrified and distance themselves.
