In fanfiction where Sally dies, it's a major turning point. Percy's character development could take a different route. Instead of having his mother as his anchor, he has to find strength within himself. This could make him more reckless at times as he no longer has that voice of reason in his life. It might also make the other characters step up more to support Percy, like Annabeth having to be more of a stabilizing force for him. And the story could then focus more on Percy's internal struggle with loss and how he copes with it in the world of demigods.
A possible plot in such a fanfic could be Percy trying to bring Sally back from the dead. He could go on a dangerous and forbidden quest, defying the gods and the natural order. This would put him at odds with many, but his love for his mother is so strong. He might encounter dark magic or make deals with shadowy figures in his desperation, all while his friends are worried about him losing himself completely in this quest.
Well, it would probably shatter Annabeth. Percy is her closest friend and love. His death would leave a huge void in her life. She might become more withdrawn, consumed by grief. She could also become more determined to carry on Percy's legacy in the fight against the forces they were up against.
Percy's death would shatter the world of those who knew him. His friends like Tyson would be inconsolable. Tyson always saw Percy as a hero and a brother. The Hunters of Artemis might also be affected. They would respect Percy's sacrifice but also feel a sense of responsibility for his death. And the gods, who had often used Percy for their own ends, might start to question their actions. Some might feel remorse, while others might fear the chaos that could follow in the wake of Percy's death, as he was often a stabilising force in the often - tumultuous world of demigods and gods.
The other characters would likely be devastated. Annabeth, his love, would be heartbroken. She might become more withdrawn and determined to avenge him. His friends like Grover would be in deep sorrow, feeling as if they've lost a part of their strength. And the whole demigod community could lose hope, as Percy was seen as a great hero.
She might read it for fun. Fanfiction can be a great source of entertainment.
Percy would be completely devastated. He might go into a state of shock at first, unable to believe that Annabeth is really gone. Then he could become filled with rage, vowing to take revenge on whoever or whatever was responsible for her death.
The demon lord can greatly impact the story by creating high - stakes conflicts. Their presence forces the heroes, like Percy and his friends, to step up and use all their skills and powers to combat the threat.
It can create a sense of urgency. If Percy throws up, it might mean he's been poisoned or is seriously ill, and his friends will have to find a way to help him quickly. This can drive the plot forward as they search for a cure or a way to make him better.
Percy might be very confused at first. He would wonder why his mother, who has always been there for him, suddenly left. He could start to question if he did something wrong. In some fanfics, he may go into a state of denial, not wanting to believe that she's really gone.
Percy would be extremely angry. He loves his mother deeply, and her disownment would feel like a huge injustice. He'd probably want to immediately go and confront the people who disowned her. Maybe he'd also feel guilty, thinking it's his fault as a demi - god that his mother is in this situation.
