Q: Your MC is told they have five days to live. There is NO way to avoid it. What do they do with their time?
Depends when in the course of the story it happens. If it's towards the end then:
A.: he would freak out because there is no-one to replace him as king… well, except for that rebellious kid who's being manipulated by the evil guys, but that's the last person A. wants as a successor! He would spend his last days begging and begging the Gods to free the only people who can help, and when that fails, he would make sure to go out with a bang. Preferably in a way that motivates the kingdom to stay together.
K.: he would hand his responsibilities over to his cousin and find a way back to his son. He would spend his last days with him.
A.: she would get everything in order, give away her belongings, send a message to her parents (since she wouldn't be able to get to them in time) and then do something really, really crazy that would otherwise have resulted in her death. During the rest of the plot, she's always afraid of doing the "right" thing because it will likely end up killing her, but since she's going to die anyway, may as well do it, right?
Question: What was your MC like as a child? Do they have good memories from their childhood? Any particular events that influenced them a lot?
