Harry Potter might visit ancient magical sites around the world. In Egypt, he could explore the pyramids which are filled with ancient spells and hidden chambers. He may also learn about different forms of magic practiced by local wizards in various countries.
He could make friends with a wizard from Australia who has a special ability to communicate with animals native to the Outback.
In this fanfiction, Harry might visit magical places in different countries. For example, he could go to Japan and discover a hidden magical forest filled with unique magical creatures that are not found anywhere else. Maybe he'll also encounter a new type of magic that is only practiced in that part of the world.
In this fanfiction, Harry might see a world where magic has evolved in unexpected ways. For example, there could be new spells that are far more powerful and complex than the ones he knew. He could also find that Hogwarts has changed, perhaps with new buildings or different teaching methods. And maybe he would encounter descendants of his friends, who have their own unique stories to tell.
Well, they could have all sorts of adventures. Maybe they'd visit different magical and alien worlds. The Doctor could show Harry some truly out - of - this - world places that even the wizarding world hasn't seen. And Harry could introduce the Doctor to the magic of Hogwarts, like the secret passages and the magic spells.
In fanfiction, Harry and Kreacher could be seen exploring the different terrains of Westeros. Maybe they stumble upon the Iron Islands. Kreacher could be fascinated by the Ironborn way of life while Harry tries to find a way to use their naval power for some greater good. Or they could end up in King's Landing and face the political intrigue there.
Harry could get involved in a quest to protect a Spanish magical artifact from dark wizards. Since Spain has a rich history, there could be many such artifacts that are important to the Spanish wizarding community. He might have to travel across different regions of Spain, from the sunny beaches to the mountainous areas, facing various challenges along the way. He'd also encounter different types of Spanish witches and wizards, some friendly and some not so much, all while trying to keep the artifact safe.
He could stumble upon a hidden wizarding community that has been cut off from the rest of the world for centuries. There, he might learn new magic spells and techniques that are unknown to the outside wizarding world.
He could have underwater adventures. The trident might give him the ability to communicate with sea creatures and explore the depths of the ocean. He could discover lost underwater cities or battle against sea monsters.
He could have adventures like using the dogs to track down dark wizards. Since dogs have a great sense of smell, they could lead Harry to places where dark wizards are hiding. For example, they might sniff out a hidden lair in the Forbidden Forest where a group of Death Eaters are planning something evil.
He could go on adventures to discover hidden vaults within Gringotts. Maybe there are vaults that have been lost for centuries, filled with ancient and powerful magical artifacts. Harry could search for these vaults, facing various traps and puzzles along the way, similar to the challenges he faced in the Philosopher's Stone.
