Yes, there are quite a few. You can start by looking on popular fanfiction websites like Archive of Our Own. Just search for 'Luke Castellan and Thalia Grace love' and you'll likely find a variety of stories with different takes on their relationship.
One common theme is the 'what if' aspect. Writers often explore what could have happened if circumstances were different and they could have been together. Another theme is the struggle against their fates. Since they both have complex roles in their world, their love is often shown as something that has to fight against those pre - determined paths.
First, you need to understand their characters well. Luke is complex, with his initial good intentions that gradually get corrupted. Thalia is strong - willed and protective. Start with a clear idea, like exploring their past friendship. For example, you could write about a time when they went on a quest together. Then, build the plot around their relationship, adding in elements from the Percy Jackson universe.
There's a fanfiction called 'Luke and Thalia: The Forgotten Days'. It's set in their early days at Camp Half - Blood. It's interesting as it explores their initial interactions and how they became friends. It also gives a new perspective on their personalities. You can find it on some popular fanfiction websites.
It can start with flashbacks to their early days at camp. Show how they were friends, shared secrets, and had each other's backs. Then, as the story progresses, introduce a conflict that tests their relationship, like Luke's growing disillusionment with the gods.
One idea could be a pre - series story where Thalia and Luke are training together in Camp Half - Blood and they stumble upon a mysterious prophecy that seems to involve them both. Another could be a story set during Luke's fall to the dark side, and Thalia tries to save him by appealing to their old friendship.
One common theme is redemption. Since Luke had some dark actions in the original story, many fanfictions explore his journey to make up for what he's done.
Luke Castellan once fell in love with a girl from the same camp. They met during a training session. He was instantly attracted to her bravery. They started to secretly meet in the forest, sharing their dreams and fears. But as Luke's path started to turn darker, their love was put to the test. Eventually, she couldn't follow him into his wrongdoings and they had to part ways.
Yes, it could be. If they are fans of certain stories or universes, loving fanfiction is quite normal as it allows them to explore different scenarios and character developments within those fictional worlds.
