One interesting storyline could be a character from the original Harry Potter series having a new adventure in a dream world. Maybe Harry himself discovers a hidden power within his dreams that he has to master to defeat a new dark force. Another could be about the relationships between characters evolving in unexpected ways in this fan - created dream - like setting.
Some storylines might involve time - travel within the dream world. A character could go back in time to the founding days of Hogwarts in their dreams and witness the creation of the four houses. They might then bring back some ancient magic or knowledge from that time which affects the present day in the fanfiction world. This could lead to new spells being discovered or old rivalries being re - ignited in a different way.
It's hard to say for sure without reading it, but it could be Harry Potter himself still being a central figure. Hermione and Ron might also be there, as they are so important in the original series. There could also be new characters created by the fanfic author, like a mysterious dream - walker who has the ability to move between different dreamscapes in the wizarding world.
One interesting storyline could be about alternate versions of the Triwizard Tournament. Maybe in the fanfiction, the tasks are even more dangerous and creative, with different characters getting involved in unexpected ways. For example, Neville could be a surprise champion and show his hidden talents during the tasks.
In some fanfictions, Alexstrasza could be a hidden protector of Hogwarts. Since she is a very powerful being, she might have been secretly watching over the school for centuries. When Harry arrives, she reveals herself and offers her assistance, especially in dealing with the dark creatures that lurk around the school and are allied with Voldemort.
Another storyline might involve an Ogron having a unique magical ability that Harry Potter discovers and uses to their advantage. For example, the Ogron could be able to communicate with a certain type of magical creature that holds the key to a powerful spell or a hidden treasure. This would lead Harry and his friends on an exciting adventure to find and utilize this newfound power.
One interesting storyline could be about an alternative Hogwarts where the houses are not sorted by the traditional Sorting Hat method. Another might be a fanfiction game story where a new, powerful magic is discovered within the Forbidden Forest. And then there's the idea of a story where Muggle - born students form a secret society to protect themselves from pure - blood bullies.
One interesting storyline could be about Moony mentoring Harry in controlling his magic. Since Moony has experience with his own unique magical condition, he could offer valuable advice to Harry. Another could be them working together to uncover a secret society within Hogwarts that has been long forgotten.
Well, there might be a storyline where the characters at the Harry Potter camp have to compete in a special magical tournament. This tournament could involve tasks like flying on brooms through a dangerous maze in the forest near the camp, or solving complex magical riddles. It would be a great way to show the different skills and personalities of the characters. Also, there could be a story where a group of students form an alliance to fight against a dark magic that's starting to seep into the camp, like a shadowy presence that's making the magical plants wither.
One interesting storyline could be about the characters exploring new magical realms within Elysium. For example, they might discover ancient spells or magical creatures that were previously unknown. Another could involve the characters having to face new challenges that are unique to Elysium, like a strange magical phenomenon that disrupts their magic. And some fanfictions might focus on the relationships between the characters evolving in this new setting.
One interesting storyline could be about the backstories of the Hogwarts staff. For example, a fanfiction might explore Professor McGonagall's early days as a witch, her training, and how she came to be so strict yet fair. Another could focus on Filch and his relationship with the students from a different perspective, perhaps showing a more sympathetic side to him.
In some fanfictions, Dobby might form an unlikely friendship with other Hogwarts students. He could teach them about house - elf magic, which is something not really covered in the original books. For instance, Dobby could show them how to use his brand of household magic for protection spells around the school during the dangerous times when Death Eaters are on the prowl.
