In some fanfictions, Percy might be sent back in time to a period when the gods were more actively involved in battles. He then has to navigate the complex politics of the time, deal with the more primitive and violent versions of the gods, and use his modern - day knowledge and skills to change the outcome of some crucial battles. This could also lead to him changing the future in unexpected ways, creating a whole new set of challenges for him.
Some fanfictions might explore a plotline where Percy's new status as the God of the Unseen causes a rift between him and his friends.

Additionally, there could be a plot where Percy discovers ancient prophecies related to the God of the Unseen and has to figure out how to fulfill them without sacrificing his own values.
Another plotline could involve the eldest god having a prophecy related to Percy. This prophecy could force Percy to make difficult choices between his loyalty to his friends and his newfound role in the eldest god's plans. For instance, he might have to sacrifice a chance to save a friend in order to fulfill a greater purpose for the world as dictated by the eldest god.
Another plotline could involve Percy making a deal with the God of Death.
