There's a possibility that he'll face new challenges. It could be a place full of dark magic or dangerous creatures. Harry would have to use his wits and skills to overcome these challenges, and this could be a great opportunity for him to grow as a wizard.
It's possible that he'll embark on a quest for knowledge. Audoron could be a place full of ancient libraries or wise wizards who can teach him things that he could never learn in Hogwarts. He would then go on a journey to find these places and people, and along the way face various obstacles.
In this fanfiction, perhaps Harry discovers a new side of himself. He might face challenges in Auradon, like adjusting to its different rules and values compared to his previous place. Maybe he forms unexpected friendships or rivalries.
In the 'Percy Jackson Gets a Second Chance' fanfiction, he could form stronger alliances. Maybe he'd reach out to some characters he didn't fully trust before. He could also use this second chance to get closer to his family, like his mom, and protect her better from the threats of the mythological world. He might even be able to prevent some of the major disasters that happened in the original story.
In some fanfictions, they might go there to search for something. Maybe they are looking for a magical artifact hidden in Australia. It could be a powerful charm or a lost spellbook that could help them in their fight against the Dark forces.
Perhaps they discover a long - lost vault. It could be a vault that contains powerful artifacts or important secrets about the wizarding world. This discovery would likely put them in danger as various dark forces would be interested in getting their hands on whatever is in the vault.
In fanfiction, they might initially face hostility from some at the Burrow. Since Harry and Draco have a history of enmity, the Weasleys might be suspicious of Draco. However, as the story progresses, they could gradually come to understand each other. For example, Draco might show a different side of himself, like his knowledge of certain magic that could be useful to the Weasleys. And Harry could act as a mediator between Draco and the others at the Burrow.
Perhaps they get involved in the American wizarding politics. The political situation in the American wizarding world might be different from that in the UK. Harry and Hermione, with their experience from the fight against Voldemort, could contribute to solving some problems in the American wizarding community, like issues related to the secrecy of magic in a more urbanized and diverse American society.
Well, it could be about Harry getting a chance to redo a crucial event in the wizarding world. Maybe he has the opportunity to save someone he previously lost, like Sirius Black. He could use his knowledge from the first time around to outwit Voldemort in a different way, leading to a more peaceful resolution in the wizarding world.
Harry himself is obviously important. There could also be characters like the princes and princesses in Auradon who interact with him. Maybe Mal or Evie would play significant roles as they are key characters in the Auradon world.
He could find himself in a really tough situation. For example, if he's in the middle of a feud between two magical factions in the fanfiction. He would have to use his wits and skills to try and find a way out or a solution that satisfies both sides. He might also start to question his own beliefs and loyalties as a result of being in this middle position.
