Another possibility is that his death is part of a tragic plot device. It might be used to create a sense of pathos and make the story more memorable. For example, his death could be due to a misunderstanding that couldn't be resolved in time, leaving the heroine heartbroken.
One possible reason could be a broken heart. If she was deeply in love and got rejected or betrayed, the emotional pain might be too much to bear. For example, in some stories, the girl loves a guy who turns out to love someone else, and she becomes so devastated that she loses the will to live.
There are several possible reasons. Firstly, for the sake of drama. It makes for a very intense and emotional story when a beloved character like Percy dies. Secondly, it could be to explore the after - effects on the other characters. How would Annabeth cope? How would the Camp Half - Blood react? Also, it might be a way to show the unforgiving nature of Tartarus.
Often, in fanfiction, Katniss might die due to political intrigue. The Capitol could come up with a more devious plan to get rid of her. Maybe they frame her for something she didn't do, and she is executed as a result. Another reason could be that she is betrayed by someone she trusts, which leads to her death.
In some 'The Land of Stories' fanfictions, Alex may die as a result of a self - sacrifice. This could be to save the Land of Stories or her loved ones. It adds a layer of heroism and martyrdom to the story. Also, some writers might use Alex's death to explore the concept of mortality in a fantasy world that is otherwise full of magic and wonder. This can make the story more thought - provoking and deep, as it contrasts the usual happy - go - lucky nature of the original series.
A possible reason could be to explore different narrative paths. By having Peeta die, the fanfiction can take a completely different turn. It could lead to a new kind of rebellion or a different way of dealing with the Capitol. Maybe the writer wants to show that in the Hunger Games world, no one is truly safe, not even a beloved character like Peeta. This can also be a way to comment on the futility of hope in such a cruel world.
There could also be some sort of genetic or pre - existing condition that the baby has. In the fanfiction world, the mpreg concept may come with its own set of genetic anomalies. If these are not properly addressed or monitored in the nursery, it could lead to the baby's death.
One reason could be that dogs have different biological processes and are more vulnerable to certain health issues. Also, their exposure to the environment and potential accidents can contribute to earlier deaths.
