One reason could be that the writer wants to create a more angsty and dramatic story. Sally's death would be a huge shock to Percy and the readers. Another reason might be to test Percy's character, to see how he would handle such a great loss.
Well, in some fanfiction, Sally might die to set up a new power dynamic. For example, if Percy loses his mother, he might be more vulnerable and have to seek new alliances. Also, it could be a way to explore themes of mortality in the Percy Jackson universe. Since Sally is a mortal, her death can highlight the differences between mortals and demigods, and how the demigods deal with the loss of their mortal loved ones.
In fanfiction, Sally's death could be a plot device to drive Percy into a darker place. Maybe the author wants to show how Percy could be corrupted by grief. Or perhaps it's related to a prophecy where her death is necessary for some greater good in the world of the story. It could also be that the writer wants to show the harsh reality of the world Percy lives in, where even the people he loves are not safe, and this could be a way to add more depth and realism to the fanfiction.
In some fanfictions where Sally dies, it could lead to Percy being filled with a new kind of rage and determination. He might become more withdrawn at first, shutting out his friends as he grapples with the loss. But eventually, it could fuel his growth as a hero, making him more fearless in the face of danger because he has already lost the most important person to him.
Maybe he faced an extremely powerful enemy that he couldn't overcome. It could be a new and terrifying monster created by the Titans or some other dark force.
First, in the original Percy Jackson story, Sally is a loving mother. Changing this fundamental aspect of their relationship goes against the established character traits. Second, it's an extremely disturbing and inappropriate concept, especially considering the target audience of the Percy Jackson series which includes young readers. Third, it violates the positive and family - friendly atmosphere that the series has created.
One great 'Percy Jackson and Sally Jackson Fanfiction' is 'A Mother's Love'. It beautifully explores Sally's relationship with Percy in a more in - depth way. It shows how Sally's love for Percy is unwavering and how she is always there for him, even in the face of the most difficult challenges that come with Percy being a demigod.
One possible fanfiction could be about Sally Jackson making lemonade for Percy and his friends during a hot summer day at Camp Half - Blood. It could show a warm mother - son moment between Sally and Percy, with the lemonade as a symbol of comfort and home in the midst of the chaos of the demigod world.
A fanfiction might revolve around a day in the life of Percy and Sally. The lemon could be part of a recipe that Sally is making when suddenly something from the demigod world interrupts. For example, a monster is drawn to the smell of the lemon dessert she's preparing, but Percy is there to save the day. It could show the normalcy of their life mixed with the chaos of the demigod world.
There's a fanfiction called 'Sally's Hidden Past' which is quite interesting. It explores Sally's life before Percy was born, uncovering secrets and events that shaped her into the strong mother we know in the Percy Jackson series. The author does a great job of building a backstory that feels both believable and engaging.
Another reason might be that she is forced to leave. There could be a magical or divine force at play. Maybe a god or goddess, who has some grudge against Percy or his father Poseidon, manipulates the situation so that Sally has no choice but to abandon Percy. This would add a lot of drama and conflict to the fanfic.
Another theme is the mystery of Sally's past. Since she has some connection to the demigod world, fanfictions often explore what she might have been through before Percy was born. This could include her own encounters with gods or other demigods, which adds depth to her character.
