One idea could be that Cedric, having survived, becomes a key figure in the fight against Voldemort. He might use his popularity and influence among the students to unite them against the Dark Arts. For example, he could start a secret dueling club where students practice defensive spells in preparation for potential attacks from Death Eaters.
Perhaps Cedric discovers a hidden power within himself after his near - death experience. This power could be related to an ancient magic that has been long forgotten. He then teams up with Harry and his friends to explore this new magic and how it can be used to defeat Voldemort. He could also share his knowledge with other students to strengthen their magical abilities.
Cedric could also play a role in uniting the different houses at Hogwarts. Since he is well - liked by all, he could start inter - house events and competitions that promote unity. This newfound unity among the students could be a powerful force against Voldemort's attempts to divide and conquer. In the final battle, the united students of Hogwarts, led in part by Cedric, could turn the tide against the Dark Lord.
Another plot could involve a time - travel crossover. Cedric somehow travels back in time and meets a younger Harry. They work together to change certain events that would have led to Cedric's death in the original timeline. This could also involve Cedric teaching Harry some of the Hufflepuff values and spells that he might not have known before.
One common plot idea is a what - if scenario where Cedric survives the Triwizard Tournament. For example, he and Harry could become closer friends and work together to face other challenges in the wizarding world.
One plot idea could be that Harry Potter's sister is also a student at Hogwarts. She meets Cedric Diggory during a Quidditch match. They start off as friends, sharing a love for the sport. As time goes on, they discover they have more in common, like a passion for magical creatures. They end up going on adventures together in the Forbidden Forest to study these creatures.
One idea could be that they face challenges in the wizarding world due to their unique situation. For example, some traditional wizarding families might not accept a female Harry and her relationship with Cedric, let alone the pregnancy. Another plot could involve how they deal with the upcoming baby's magic potential and the responsibilities that come with it. They might also have to protect the baby from dark forces that see it as a threat or a tool for their own purposes.
They might become closer friends. Cedric could be grateful to Harry for trying to save him during the Triwizard Tournament, and Harry would be glad that Cedric survived. They could start sharing their experiences and knowledge about magic more often, and perhaps even train together to become better wizards.
One plot idea could be Cedric trying to teach Sofia a new and unique magic spell. Maybe it's a spell that's been forgotten for ages, and together they embark on a journey to find the missing elements to complete it. Another could be Cedric getting into trouble and Sofia has to use her wits and kindness to get him out of it. For example, he accidentally turns a beloved palace pet into something strange, and Sofia has to find a way to reverse the spell without getting Cedric in too much trouble with the king and queen.
A great plot for a Potter Manor fanfiction could involve a mystery that surrounds the manor. For instance, strange noises at night lead Harry to uncover a long - forgotten chamber. It could also be about Harry restoring the manor to its former glory, perhaps with the help of Hermione's research on ancient magic used in the construction of such manors.
One interesting plot idea could be exploring what would happen if Harry had a different upbringing, like being raised by the Malfoys. It would completely change his view of the wizarding world and his relationships. Another idea might be a time - travel fanfic where Harry goes back to the Marauders' era and interacts with his parents and their friends. This could lead to him preventing certain tragedies or changing the future in unexpected ways. And then there's the concept of a fanfic where the roles are reversed, and Voldemort is the one trying to protect the wizarding world from a greater evil, with Harry being the main antagonist.
The fanfiction could show that Harry discovers a secret passage that leads to where Cedric is held captive. He has to face various magical traps and challenges on the way. Once he reaches Cedric, he uses his Gryffindor courage and his knowledge of magic, like the Shield Charm to protect Cedric from incoming spells, and then they escape together, with Harry being the hero who saves Cedric.
A traveler could be from a different magical realm entirely and come to the Harry Potter universe. They bring with them unique magical abilities that both fascinate and frighten the wizards in the Harry Potter world. This could lead to a series of adventures where they either share their knowledge or are hunted down by those who fear the new magic they possess.
