One great Percy Jackson fanfic set in Britain could be one where Percy and his friends visit an ancient British site like Stonehenge. In this fanfic, they might discover a hidden entrance to a demigod realm that was long forgotten. The British setting could add a whole new layer of mystery and magic, with different mythologies overlapping.
The characters would have to adapt to the different time period. For example, Percy would probably have to wear the clothing of the 1700s, which would be quite different from his modern attire. His way of speaking might also change slightly to fit in better.
One possible plotline could be Percy Jackson finding himself in the 1700s and having to deal with the different forms of mythological creatures that were more prevalent during that time. Maybe he has to stop an ancient evil that was sealed away centuries ago but is now being awakened in the 1700s due to some dark magic rituals.
Yes, in some Percy Jackson fanfics, he could be depicted as a Titan. Fanfic writers often take creative liberties and might come up with unique storylines where Percy has Titan - like qualities or is even reimagined as a Titan for the sake of an interesting plot twist.
A simple plot could be that Percy has nightmares about the eruption. These nightmares start to affect his daily life at Camp Half - Blood. He then decides to go back to the site of Mt St Helens to face his fears. Along the way, he discovers a hidden prophecy related to the event.
In a fanfic, perhaps Percy and his friends accidentally stumble upon Medusa's lair while on a quest. But instead of immediately attacking, Medusa offers them a deal. She says she will give them a valuable clue to complete their quest if they help her get revenge on one of the minor gods who wronged her in the past. Percy and his friends then have to decide whether to trust Medusa or not.
A positive fanfic idea could be Percy mentoring new demigods at Camp Half - Blood. This would show his growth as a character and his ability to pass on his knowledge and skills. Also, a fanfic about Percy and his friends exploring a lost city full of ancient magic and mystery would be really exciting. It would stay true to the adventurous spirit of the original series without any inappropriate content.
One good topic could be Percy's exploration of different parts of the Underworld that weren't covered in the books. It could be about his encounters with new spirits and his attempts to navigate the unknown regions. Another topic might be the backstories of the minor characters at Camp Half - Blood. How they came to the camp, their initial struggles, etc.
In Percy Jackson and Annabeth fanfics, the relationship between them can be developed in various ways. Some might show their daily life at Camp Half - Blood in more detail, with little arguments and sweet reconciliations. Others could take them on a quest that's not in the official series, adding new monsters and challenges for them to overcome.
Scars in Percy Jackson fanfic are not just physical marks. They can be a connection between the character and the mythology. For example, a scar that was given by a mythical creature might have some special power or significance. It could be a key to unlocking a hidden prophecy or a way to communicate with otherworldly beings. This adds an extra layer of mystery and magic to the story.
