Fanfiction about female Percy getting banished: What could be the possible reasons for her banishment?

Well, perhaps in the fanfic, there's a prophecy that gets misinterpreted. The gods think Percy is going to cause great harm based on this wrong interpretation, so they send him to Tartarus. It could also be that there's some sort of power struggle among the gods. Percy might be caught in the middle of it, and one side decides to get rid of him by banishing him to Tartarus to tip the balance in their favor.

In the context of this fanfiction, Naruto's family might banish him because they don't fully understand his 'godlike' powers. They see the surface level of his new strength and assume the worst. Maybe they think he has been corrupted by some unknown force. Also, it could be related to power politics within the family. Some members might see Naruto's power as a threat to their own position and influence, and so they convince the rest of the family to banish him to safeguard their own interests.

One possible reason could be that they are wrongly accused of a serious crime within the wizarding world. Maybe some dark magic items are found in their possession and the authorities suspect them of being involved with dark wizards, without fully investigating the real source of those items.

Perhaps Draco has been bullying some of Percy's friends or younger students that Percy feels responsible for. In fanfiction, the relationships can be tweaked a bit. Percy might be more hot - headed in some versions and not put up with Draco's pure - blood supremacist attitude towards those he deems as 'lesser' students. So he sends the Howler as a strong warning.

In some fanfictions, Percy might be banished because he goes against the traditional ways of the demigod society too much. For example, if he tries to form an alliance with a group that the other demigods consider enemies. His actions could be seen as a threat to the stability of their world, so they banish him to keep the peace.

Perhaps a prophecy misinterpretation. If a prophecy was misread and it seemed like Percy was the cause of great evil to come, the gods might take drastic action. For instance, if the prophecy spoke of a 'child of the sea' causing destruction, and they wrongly assumed it was Percy without fully understanding the context.

Well, it could be related to Percy's past actions. If he has a history of being unreliable in the eyes of the character rejecting him, that would be a valid reason. For instance, if he has broken promises in the past. Or perhaps there are external factors at play. Maybe the family of the person rejecting Percy doesn't approve of him, so they influence the decision. Another aspect could be that Percy is too different in terms of values. If he values adventure and risk - taking above all else and the other character values stability and safety, it can lead to a rejection.

Well, one reason could be that he's wrongly accused of a major crime against the gods. Maybe some false evidence is planted, making the gods believe he's a threat, so they banish him. Another reason might be that he's trying to protect someone or something, and his actions are misinterpreted as going against the gods' will. For example, if he's trying to save a powerful but 'forbidden' creature, the gods might see this as a violation and send him to Tartarus.

Maybe he accidentally breaks some ancient and unforgivable rule. For example, he could have uncovered a secret that the gods wanted to keep hidden and in their attempt to silence him, they banish him. In fanfiction, the writers often play with the idea of Percy's curiosity getting him into big trouble with the Olympians.

One possible plot could be Percy's struggle to survive in a new, unknown realm after being banished. He might have to find new allies and face new enemies.
