One common theme is Percy's adventures in the service of Hecate. This could involve him going on quests for her, facing magical creatures, and using the powers she bestows upon him. Another theme is his relationship with other characters from the Percy Jackson universe. How they react to his new role as Champion of Hecate and how it affects their dynamics.
One common theme could be adventure. Given the nature of the characters, it's likely that many fanfictions involve them going on various adventures together.
Another theme is the idea of forbidden love. In the context of Greek mythology, a relationship between a demigod and a goddess can be seen as improper or against the rules. Many fanfictions play with this idea, showing how Percy and Hecate have to overcome obstacles related to this.
One common theme is the relationship between Percy and Apollo. Writers often explore how their different personalities interact, like Percy's more down - to - earth nature compared to Apollo's godly and sometimes flamboyant self.
A common theme is the clash of different worlds. Percy, coming from the demigod world, and Hecate, from the world of magic, their relationship often involves dealing with the differences between their two realms.
One common theme is family. Since Hestia is associated with the hearth, which is a symbol of home and family, fanfictions often explore Percy's family relationships more deeply. Another theme could be protection. Percy, as Hestia's champion, might be tasked with protecting something or someone related to her domain.
One idea could be Percy having to master Hecate - related magic to defeat a new type of monster that is immune to physical attacks. Another could be Percy being chosen by Hecate to retrieve a powerful magical artifact from the underworld. And perhaps Percy must use Hecate's magic to save his friends who have been trapped in a magical maze created by an old enemy.
You can start by looking on popular fanfiction websites like Archive of Our Own (AO3) or FanFiction.net. AO3 has a wide range of works and a good tagging system, which makes it easier to search for Percy Champion of Hecate fanfictions specifically. FanFiction.net also has a large collection, but the search might be a bit more challenging. You can also check out relevant fandom forums or groups on social media platforms, where fans might share and recommend their favorite fanfictions in this area.
The Titans could still be antagonists. They might see Percy as a threat in his new role as the champion of Hecate. Another could be some rogue demigods who are jealous of Percy's new power and want it for themselves. And there could be magical creatures that have been corrupted by dark magic and oppose Percy's efforts to bring balance with Hecate's magic.
A theme that can't be ignored is the theme of friendship. Even though he is the champion of Hera, his friendships still play a huge role. His friends might support him, question his actions as the champion, or even be in danger because of his new role. This creates a complex dynamic that is often explored in these fanfics. Also, the theme of destiny. Percy has to figure out if being the champion of Hera is part of his true destiny or just a new path he has to tread.
One common theme is self - discovery. Hermione, upon learning she is Hecate's daughter, has to figure out who she really is and what this new identity means for her. Another theme is power and its proper use. Since Hecate is associated with magic, Hermione often has to learn how to control and use her new - found powers in a responsible way.
