One interesting headcanon could be about the backstories of the Servants. For example, there might be a headcanon that a certain Servant had a secret friendship in their past life that influenced their character in the game. Another could be related to the magic system in the Fate Grand Order universe, like a unique way of casting spells that isn't shown in the main story.
Well, a popular headcanon is that Percy can see the memories of the ocean. So in fanfiction, he might touch an old piece of coral and suddenly be flooded with images of ancient sea battles or long - lost civilizations. Also, some think that Annabeth has a fear of heights that she hides really well because she doesn't want to seem weak. As for Grover, perhaps he has a family of satyrs in a hidden grove that he secretly visits and they tell him old satyr tales that he then uses to his advantage on quests.
I like the headcanon where Annabeth is a master of disguise. In fanfiction, she can blend into any crowd, not just because of her intelligence but also because she has some magical items that help her change her appearance. It makes her even more resourceful on quests. Grover, on the other hand, has a headcanon where he can grow plants with just a touch. So if they're in a barren area, he can create a little oasis for them to rest in. This shows his connection to nature in a more powerful way.
One idea could be that Neville Longbottom is secretly a powerful wizard all along but has been suppressing his power due to self - doubt. Another could be that the Hogwarts portraits have their own little society and gossip network within the castle walls. And a third one might be that Hagrid has a secret family of magical creatures in the Forbidden Forest that he takes care of.
It can add more depth to minor characters. For example, by creating headcanons about characters like Lavender Brown, we get to see a side of the Hogwarts student body that wasn't fully explored in the original. It gives them more personality and backstory.
A wedding in Camp Half - Blood would also be great. They could incorporate elements of Greek mythology in the decor, like having statues of the gods and goddesses around. Their friends from the camp could all be part of the celebration, making it a big, fun event.
One great topic could be their travels and exploration. For example, writing about a new quest they embark on together in a mysterious land, facing challenges and relying on each other's strengths. This would focus on their adventurous side and their strong bond as a couple in a non - sexual way.
Yes, there are many non - explicit Percabeth fanfictions that capture their intense emotions. For example, some focus on their arguments and subsequent reconciliations in a more platonic or romantic way without any sexual content. You can find them on fanfiction platforms by using keywords like 'Percabeth conflict and resolution' or 'Percabeth emotional moments'.
The Fate Grand Order Headcanons Novel can expand the game's lore in multiple ways. It can provide more details about the Servants' Noble Phantasms, their origin, and how they function. It might also offer insights into the world outside of the main story's events, such as the daily lives of ordinary people in the Fate Grand Order universe. Moreover, it could introduce new concepts related to the magic and technology in the game, which helps to create a more complex and immersive world for the players.
Their relationship can be developed through shared challenges. For instance, they could face a powerful enemy together. In the process of fighting this enemy, they would learn to rely on each other's strengths. Piper's ability to manipulate emotions could be useful in confusing the enemy, while Percabeth's sword - fighting and problem - solving skills would be crucial for direct combat and strategizing.
