One idea could be a story where Harry and Lily Luna Potter time - travel together. They could go back to the time when the Marauders were at Hogwarts and have all sorts of adventures, like helping Sirius and James avoid getting into trouble with Snape. Another plot could involve them facing a new dark wizard threat in the future. Lily Luna could show her own brand of magic, different from Harry's but equally powerful, as they team up to defeat the enemy.
A plot might be that Lily Luna Potter discovers a hidden ability within herself that she doesn't understand at first. Harry, with his years of experience, helps her figure it out. Along the way, they stumble upon an ancient mystery at Hogwarts that was long forgotten. Maybe it has something to do with a secret chamber that has a powerful magical artifact. As they explore this mystery, they also bond more as father and daughter.
One idea could be Lily Luna Potter discovers a hidden spellbook that once belonged to Harry Potter. She starts to experiment with the spells inside and accidentally opens a portal to a parallel magical world. There, she meets a younger version of Harry Potter and they have to work together to find a way back home while also facing the new and strange magical threats in that world.
One plot idea could be that Lily, Luna, and a character named Lemon discover a hidden spell in the Forbidden Forest that has a connection to Harry Potter's past. They embark on a journey to understand the spell's significance and how it might affect the wizarding world's future.
Perhaps she forms an unlikely friendship with a pure - blood Slytherin who has very traditional views. Lily Luna tries to show this friend a different perspective on blood purity and the wizarding world in general. Their friendship causes a stir in the Slytherin common room, but they stick together through it all.
One plot idea could be that they are paired for a school project at Hogwarts. At first, they are hesitant because of their families' past rivalries. But as they work together, they discover they have more in common than they thought. For example, they both have a love for magical creatures. They start to form a friendship that slowly blossoms into something more, like a budding romance. This would be a sweet and slow - burn kind of story.
One plot idea could be that Colin, now an accomplished wizard photographer, decides to document the adventures of Lily Luna Potter at Hogwarts. He could capture her unique spells and the special bond she forms with her friends, much like he did with Harry Potter years ago.
One plot idea could be that Ginny and Lily Luna Potter discover a hidden magical ability within the family that has been long forgotten. They embark on a journey to uncover the secrets behind it, facing various magical creatures and ancient spells along the way.
A possible fanfiction could involve Lily Luna Potter and her time - traveling adventures. She accidentally stumbles upon a time - turning device and gets sent back to the time of the first Wizarding War. There, she has to be careful not to disrupt the timeline while also trying to learn from the events of that time to prevent a similar future catastrophe.
One plot idea could be Lily Luna trying to prove herself on a dangerous mission despite her family's overprotectiveness. For example, she could secretly join a group that is fighting against a new dark force in the wizarding world. Another idea is that she might fall in love with someone her family doesn't approve of, leading to a lot of family drama. Maybe she meets a half - blood wizard from a family with a not - so - great reputation, and her family tries to keep them apart.
A really interesting concept could be Lily Luna Potter traveling back in time. She could meet her father as a young boy at Hogwarts and have to be careful not to disrupt the timeline. It would be a great way to see how the past and present of the wizarding world interact.
A really interesting fanfiction could be set around the time of her birth during a difficult situation in the wizarding world. For example, if there were still remnants of dark forces lurking. This would add an element of danger and drama to the story. Her birth could be seen as a symbol of hope in such a scenario, with the Potter family having to protect her from potential threats right from the start.
