A third plot idea is Percy uncovering a long - lost secret about their family. This could be something that shakes the foundation of what he thought he knew about himself and Athena. He might then have to decide what to do with this new information. Does he share it with Athena? How will it change their relationship? And how will it impact the demigod community?
One idea could be Percy trying to prove himself worthy in Athena's eyes. Since he's her brother in this fanfic, he might strive to show his intelligence and strategic skills, much like Athena is known for. Maybe he enters a competition within the demigod world that tests both physical and mental prowess.
A really interesting plot could be that because he's Athena's brother, Percy is suddenly given access to some of Athena's knowledge. But this knowledge comes at a price. He starts to lose some of his own identity as a son of Poseidon. He has to go on a journey, both physically and mentally, to find a balance between his new - found connection to Athena and his loyalty to his father. Along the way, he meets various mythological creatures who either help or hinder him in this struggle for self - discovery.
One idea could be that Percy has to seek Athena's wisdom to solve a complex mystery in the mortal world that is somehow related to the gods' ancient secrets. Maybe it involves a powerful artifact that was lost long ago and only Athena's knowledge can lead Percy to it.
Another plot could involve Percy getting a vision from Athena about a future threat to the demigod world. But the vision is so cryptic that he has to work closely with Athena to decipher it. Along the way, they build an unexpected bond, different from his usual relationships with other gods. Maybe Percy starts to see Athena not just as a powerful deity but as a mentor figure, and Athena starts to respect Percy's tenacity more than she expected.
One plot idea could be that Athena tasks Percy and Annabeth with a special quest that involves retrieving a long - lost artifact of hers. This could test their relationship as they face various challenges together. Another could be that Athena reveals a long - hidden secret about Annabeth's family that Percy has to help her come to terms with. Maybe it's something that changes their perception of their destinies within the demigod world.
One idea could be Percy having to go on a quest that involves both Athena and Artemis. Maybe he has to retrieve an ancient artifact that is sacred to both goddesses. Another could be a story where Percy gets caught in the middle of a feud between Athena and Artemis over a new demigod's loyalty. For example, the new demigod shows great skills in both wisdom (Athena's domain) and hunting (Artemis's domain), and the two goddesses start to compete for the demigod's allegiance, with Percy trying to keep the peace.
Perhaps Athena's love for Percy causes a rift between her and her daughter Annabeth. This could lead to a complex story of family drama, loyalty, and love. Or, in some fanfictions, there could be a plot where Athena's love is a curse placed on her by an enemy, and Percy has to find a way to break the curse, all while they both struggle with their new - found emotions.
One idea could be Percy going on a quest to find a lost artifact of Athena that has the power to restore balance in the world of the gods. Another could be Percy having to face off against a powerful enemy who is specifically targeting him because of his relation to Athena. Maybe he discovers some long - lost siblings also sired by Athena during his adventures.
One idea could be a new quest where Percy and Annabeth have to find a lost artifact related to Athena that was stolen by a rogue demigod. This would involve them traveling to new and dangerous places, facing off against mythical creatures they haven't encountered before.
One idea could be that Percy needs Athena's help to save his friend who has been trapped in a maze created by an ancient enemy. Athena uses her wisdom to guide Percy through the various traps and challenges in the maze. Another could be a story where Athena asks Percy to retrieve a powerful artifact that has been stolen from her temple. Along the way, Percy has to use his skills and Athena's advice to overcome different obstacles.
One plot idea could be that Percy, in his adventures, discovers a long - lost prophecy related to Athena. As he delves deeper into understanding it, he starts to develop a new - found respect and a kind of platonic love for Athena. He might see her not just as a goddess but as a key figure in the fate of the world and their relationship could be based on mutual understanding of the greater good.
