Perhaps Lily's plan in the fanfiction is related to uniting the wizarding community against dark forces. She could be planning to gather all the good witches and wizards, including those from different magical cultures, to form a powerful alliance. This would be a significant departure from the more individual - based protection in the original story.
In some fanfictions, Lily's plan could involve time - traveling. She might go back in time to change certain events that lead to Voldemort's rise. This would require a great deal of magic and knowledge. She could be working with Dumbledore in this plan, using his wisdom and her unique magical abilities to rewrite history and save the wizarding world from the threat of Voldemort.
Well, without reading the specific fanfic, it's hard to say exactly. But generally in Harry Potter fanfics, Lily could have all sorts of plans. It might be related to protecting Harry, or perhaps something to do with the wizarding world's future. Maybe she has a plan to deal with Voldemort in a different way than in the original story.
One possibility could be that the Marauders plan to prank the Slytherins in a big way. They might use their Animagus forms to sneak into the Slytherin common room and create chaos, like turning all their robes pink or making their beds float. It would be a classic Marauders' style of mischief.
Maybe in the fanfiction, Harry accidentally enters a parallel dimension where Lily is still alive. Here, Lily discovers that Harry is her future son. She might take him under her wing and train him in a different way of magic, one that was perhaps forgotten in Harry's own time. This could lead to Harry having unique powers and a different approach to dealing with the Dark Arts and his enemies.
Well, perhaps it could be about Harry growing up in a world where Lily survived. They might have a special bond. Harry could learn magic from Lily in a more personal way, and she could protect him from threats that Voldemort still poses. Maybe they'd have adventures together in the wizarding world, and Lily could introduce Harry to parts of the magical community that he didn't get to experience in the original story.
In a parallel universe fanfiction, the universe has shifted in a way that allows James and Lily to meet Harry. This could be due to a powerful spell gone wrong. James and Lily are alive in this universe and are curious about Harry, who seems to be from a different reality. They learn about his struggles against Voldemort and decide to help him, and together they work to find a way to fix the rift between the universes.
It could be about Lily Rose discovering she has magical powers related to the Potter line. Maybe she's a long - lost relative who has been living in the Muggle world and suddenly gets a letter from Hogwarts. Then she embarks on an adventure to learn magic and uncover secrets about the Potter family.
Another possibility is that Lily's plan focuses on influencing the Hogwarts curriculum. She realizes that the students need to be better prepared for dark threats. So, she plans to introduce new courses or modify existing ones to teach more practical defensive magic and the study of dark magic in a more in - depth way, all with the aim of making the wizarding world safer for Harry and others.
A really creative escape plan in Harry Potter fanfiction could be centered around the Room of Requirement. The characters could enter the room and ask it to become a portal to a safe place. The room could transform into a magical gateway that leads them to a different dimension or a hidden wizarding community. Or they could ask the room to create a series of obstacles and decoys to distract their pursuers. While the enemies are dealing with the fake threats, Harry and his friends could quietly slip out through a secret exit that the room provides.
Well, perhaps Lily Potter discovers a magical time - traveling device. She could end up in a future where Hogwarts has changed drastically. Maybe there are new spells and magical creatures that she has to adapt to. And she might meet her descendants or future versions of her friends.
One possible main plot twist could be that Lily's magic, being different from the Dursleys', has a profound impact on Harry's early development. Maybe he starts showing advanced magical abilities much earlier because of Lily's nurturing and magical heritage. Another could be that the wizarding world has a different view of Harry since he was raised by a powerful witch like Lily, and they either fear or overly idolize him from the start.
