Magic and discovery are common too. As a little sister, Lucy may be the one who discovers new magical elements in Narnia. Writers might play with this idea, having her find hidden spells or magical creatures. Her innocence as a little sister can make these discoveries even more exciting and sometimes a bit more dangerous as she might not fully understand the implications at first. And of course, there are often themes of loyalty, both to her family and to Narnia itself, which are intertwined with her role as a little sister.
One common theme is family dynamics. Since she's seen as a little sister, there are often stories exploring her relationships with her siblings in more depth, like how they protect her or how she tries to prove herself to them. Another theme is growth. Lucy might be portrayed as growing up in Narnia, learning more about the magical world and her place in it as a little sister.
You can start by looking on fanfiction websites like Archive of Our Own (AO3). Just search for 'Lucy Pevensie little sister' in the search bar, and it should bring up a bunch of relevant stories. There are often tags and filters you can use to narrow down the results, such as the genre you prefer, like adventure or friendship based stories.
A third common theme is the exploration of new magical adventures. Writers of fanfiction love to send Harry and Lucy on quests that neither of them could have had in their original stories. These adventures might involve exploring new magical lands that are a blend of Narnia and Hogwarts - like settings, or encountering strange and powerful magical creatures that are a combination of the ones from both series. This theme adds an element of excitement and novelty to the fanfictions.
The theme of redemption can also be found. Sometimes an original character has made mistakes in the past and through their interactions with Peter, they seek redemption. Additionally, the theme of family is there. Even though the original characters are new, they often become part of Peter's 'family' in Narnia, and they learn the importance of family bonds and loyalty.
One common theme is the exploration of identity. Since Edmund is male in the original and now being female in the fanfiction, there's a lot of self - discovery about what it means to be Edmund in a different gender. Another theme is relationships. How does a female Edmund interact with the other characters like Peter, Susan, and Lucy? It often shows different dynamics.
One common theme is redemption through pain. Edmund has a past of making mistakes, and in hurt fanfiction, his suffering can be a way of atoning and growing. Another theme is the strength in vulnerability. When he's hurt, it shows his human side and how he can still be strong. For example, in some fanfictions, after getting injured in a battle, he continues to fight for Narnia.
There's also 'Lucy's Secret Journeys'. In this fanfiction, Lucy discovers a hidden power within herself and Peter has to help her control it. It's full of emotional moments and great character development. The author does a wonderful job of staying true to the original characters while adding new twists.
A recurring theme might be the struggle for acceptance. People might have certain expectations of her because she's related to Harry. Some might expect her to be just as brave or talented as him, while others might be jealous or suspicious. So, the fanfiction could focus on how Lucy deals with these different attitudes and tries to be accepted for who she really is in the wizarding community.
One common theme is the clash and combination of different magical systems. Since Harry comes from the wizarding world of spells and potions and Susan has her Narnian magic, their fanfics often explore how these two types of magic interact. Another theme is friendship. They are from different fictional universes, so when they meet, their developing friendship is a big part of the story.
The theme of friendship across different worlds is also prevalent. Harry and Peter, coming from different fictional universes, form a bond in fanfictions. This friendship often becomes a powerful force against any threats they face together, and it also helps them understand each other's cultures and values better.
There might be a fanfiction where Lucy and Peter go back in time to the very beginning of Narnia. They witness the creation of the magical world and play a role in ensuring its future. In this story, they could interact with the great lion Aslan in a whole new way, perhaps learning secrets about Narnia's origin that no one else knows.
