What are some interesting plot ideas for a 'Harry Potter Forgotten Realms' fanfic?

Harry himself would also be a great focus. His experience with facing dark wizards in his own world would be put to the test in the Forgotten Realms. He could have to learn new magic quickly to survive and also figure out how to use his existing powers in a world with different magical rules. His connection to Voldemort might also play an interesting role, like if Voldemort's influence somehow seeps into the Forgotten Realms.

One interesting plot twist could be that the forgotten twin has a different magical ability than Harry. For example, while Harry is good at Defense Against the Dark Arts, the twin might be a natural at Potions or Charms. This could lead to a situation where the twin is initially seen as an outcast in Hogwarts because their skills don't match the typical Gryffindor traits. Another plot twist could be that the forgotten twin was actually hidden away by a powerful dark wizard who planned to use the twin's power for their own evil purposes. This would put the twin in a difficult position when they discover their true past and have to decide whether to side with the forces of good or be influenced by the dark wizard's plans.

One idea could be that a dragon escapes from Gringotts and Harry has to use his skills to track it down. Maybe the dragon has a special connection to a powerful dark magic item that Voldemort was after.

One idea could be that Voldemort somehow enters the Runescape world to seek more power. Harry and his friends follow him there to stop him. They have to learn the rules of Runescape quickly to be able to fight Voldemort. Another idea is that a Runescape wizard discovers a portal to the Harry Potter world and brings some of the unique items from Runescape, like special runes, which causes a stir in the wizarding world.

A great plot for a Harry Potter academy fanfic might be a time - travel scenario. A group of students accidentally travel back in time to the founding days of Hogwarts. They have to navigate the different rules and attitudes of that era while also trying not to change history too much. Or perhaps there's a plot where a student is wrongly accused of a major crime at the academy and has to prove their innocence. They'll need to use their wits and the help of their friends to find the real culprit.

Perhaps in the fanfic, the snake is a key to unlocking an ancient magic that has been lost in the wizarding world. This could lead to a whole new adventure for Harry and his friends as they try to understand and use this magic.

One idea could be a fanfic where a character discovers a long - lost wand with a special power. For example, a wand that can open portals to different magical realms. The character then has to figure out how to use this power without getting into too much trouble with the Ministry of Magic.

One interesting plot idea could be exploring what would happen if the Sorting Hat made different decisions for the main characters. For example, if Harry was sorted into Slytherin instead of Gryffindor, his entire journey would be radically different. He might have had different friends, different enemies, and a different approach to dealing with Voldemort.

One idea could be a crossover where characters from both universes meet. For example, Harry Potter could encounter Eragon and they could learn from each other's magic systems. Maybe Harry could teach Eragon about some of the more complex spells in the wizarding world, while Eragon shows Harry how to bond with a dragon in a more in - depth way.

You could also create a plot where a character who thought they had no connection to the Potter heritage suddenly discovers they do. This revelation could change their entire life. They might have to deal with newfound magical abilities that come with the Potter bloodline, and also face the enemies that the Potter family has made over the years, like some die - hard Death Eaters who still hold grudges.
