In this fanfiction, Percy and Thalia could meet a powerful sorcerer who has been exiled from the magical community. The sorcerer could see potential in them and offer to teach them some ancient magic spells that could be useful against their enemies. Additionally, they may come across a group of forest spirits. These spirits could be initially hostile but after learning of Percy and Thalia's noble intentions, they could provide them with shelter and information about hidden paths that lead to safe places away from the threats they are running from.
They could meet other demigods who are also on the run or lost. These demigods might have different powers and backgrounds, and together they could form a sort of 'runaway group'. For example, they might meet a demigod who has the power of controlling plants and can help them find food and shelter in the wild.
In such a fanfiction, they might run away to avoid some great danger in the Camp. Maybe they discover a plot against demigods and feel they can't trust anyone there, so they set off on their own to find a way to stop it.
He might encounter new demigods who are also on the run or hiding from the traditional demigod society. These could be demigods with different powers or backgrounds that Percy has never seen before.
Percy might meet an old enemy who has somehow been resurrected or changed in the future. This enemy could be more powerful and have a new plan to take over the world or destroy the demigods. Or he could meet a group of time - traveling demigods from an even further future who are trying to fix something in Percy's future that has gone wrong.
It could be that they run away to find someone. Maybe a missing demigod friend or a powerful being who can help them with a problem they're facing. Percy, Thalia, and Nico might have received a mysterious message or a vision that leads them on this journey. As they run away and start their search, they encounter various obstacles. They have to cross dangerous terrains, deal with unfriendly gods or demigods who don't want them to succeed, and also figure out how to work together effectively. Their friendship is tested, but in the end, they grow stronger together.
Percy might run into Loki. Loki is known for his trickery. He could either befriend Percy for his own devious plans or try to deceive him. Percy, being used to dealing with tricky situations in his own world, would have to be on his guard against Loki's schemes.
Percy's powers might evolve in terms of his connection to the sea. Maybe he starts to communicate with sea creatures in a more profound way. He could ask for their help in escaping pursuers or finding food and shelter. Thalia's power over lightning could also be related to her emotions more closely. As she faces different challenges during their escape, her lightning bolts could become more powerful depending on her state of mind. Nico, on the other hand, might start to have more control over the undead. He could use them as scouts or to create distractions when they're in trouble. This evolution of their powers would be a result of the new and difficult situations they face while running away.
He might meet other inter - galactic beings. For example, some sort of space - faring demigods from a far - off galaxy. Or he could encounter powerful entities that are the rulers of other planets.
In his new life, Percy could meet a kind - hearted librarian. She would be the one to introduce Percy to a whole new world of books that he never had time to explore before. There's also a chance that he'll meet a street - smart kid who helps Percy navigate the more mundane aspects of his new life, like finding the best places to eat or how to fix his bike. And perhaps a new teacher who has a mysterious past and seems to have an inkling of Percy's true nature.
He might meet a new teacher who is secretly a minor god or goddess in disguise.
