Another plotline could be that a jealous demigod, who has some minor powers of persuasion that they've developed into a form of hypnosis, targets Annabeth out of envy. This demigod wants to make Annabeth look bad in front of Percy and the others. Percy, being in love with Annabeth, quickly realizes something is wrong and sets out to find the source of the hypnosis and free Annabeth from its control. Along the way, he has to deal with the challenges of the hypnosis - affected Annabeth's actions.
One possible plotline could be that a new villain, who has powers of hypnosis, targets Annabeth because of her strategic mind. The villain wants to use her knowledge of Camp Half - Blood and the demigod world to their advantage.

Perhaps Annabeth is wrongly accused of a crime and is made a slave as punishment.

Another plotline could be centered around Annabeth's jealousy when other characters show interest in Percy. So she's constantly thinking about Percy and how much she wants him all to herself.

Another plotline could be that they are babysitting a group of demigod toddlers at Camp Half - Blood. The toddlers keep getting into mischief, like stealing nectar and ambrosia. Percy and Annabeth have to keep them in line, teach them about the rules, and also make sure they don't accidentally harm themselves with their budding powers. It could be a really cute and chaotic story.
One possible plotline could be Percy going on a desperate search for Annabeth. He might start by retracing her last known steps, asking all their mutual friends and allies if they've seen her.

And he could also discover some hidden secrets about Annabeth's past during the search that he never knew before.
One possible plotline could be Percy trying to escape the Hydra experiment facility while using his demigod powers. He might have to fight off Hydra agents and other dangerous creatures they've created through their experiments.
A possible plotline could be that Percy is somehow cursed to be a forgotten god. He has to figure out who cursed him and why. In his quest, he may find that there are other forgotten gods and goddesses who are also trying to break free from the same fate. He could team up with them and use his unique skills as Percy Jackson, even in his forgotten state, to fight against the forces that are keeping them in obscurity. This could involve battles with powerful magical entities, exploration of long - lost realms, and the discovery of new powers within himself that are related to his new 'forgotten god' status.
In this fanfiction, the imprinting might also be a source of internal conflict for Leah.

Maybe she has to make a choice between following Percy on his adventures and fulfilling her own responsibilities, and this internal struggle could drive the plot forward.
In the 'Percy Jackson After the War Fanfiction', a plotline could be about the demigods integrating with the mortal world more. Percy, being a half - blood, has always had one foot in each world. Now, after the war, he might be more determined to make the two worlds coexist peacefully. He could start initiatives at Camp Half - Blood to teach demigods about mortal culture and vice versa. Another aspect could be the power dynamics within the demigod community. With some of the major villains defeated in the war, new leaders could emerge. Percy might not be interested in being a leader but could be thrust into that role. And finally, there could be a story about how the demigods deal with the memories of those who died in the war. They could create memorials or have special ceremonies to honor the fallen.
