Perhaps there is a character who is a bit of an outcast at first. He or she has a different way of thinking compared to the others. But as the story progresses, this character becomes crucial in finding a new place to live or a new source of food. There might also be a character who is a healer, taking care of the wounded and sick in the group.
Well, the theme of human nature is probably prominent. When the world has fallen, people's true natures come to the surface, whether it's their kindness in helping others or their greed in hoarding resources. Also, the search for meaning in such a desolate world could be a theme. Characters might be constantly looking for a purpose to keep going.
I'm not entirely sure as I haven't read it in full. But generally, it might be about a world that has undergone some sort of major catastrophe or change. It could involve the struggles of the characters in this new, post - fall world, perhaps dealing with new rules, new threats, and trying to find their place or purpose in this altered reality.
The 'world after the fall novel' could potentially center around a world that has been devastated by some sort of cataclysmic event. It may follow the journey of the main characters as they navigate this new and dangerous world. They could be dealing with things like scarce resources, mutated creatures, or power struggles among the remaining groups of people. Without reading it, this is all speculation based on common themes in this type of novel.
One of the main themes could be survival. In a post - fall world, characters likely have to fight for their lives against various threats. Another theme might be the re - building of society. As the old world has fallen, there's the process of starting anew. And also, there could be a theme of self - discovery, as the characters navigate this new and dangerous world and learn more about themselves.
The protagonist is often one of the most interesting characters. They usually have a unique journey and growth throughout the story. Maybe there's a character with some special power that makes them stand out. For example, a character who can manipulate the environment in this post - fall world would be really cool and interesting.
The main theme could be about redemption. After a fall, whether it's a moral, physical or emotional one, the characters might strive to redeem themselves.
I'm not sure exactly as I haven't read the novel. But it could be a protagonist who is trying to overcome the consequences of the 'fall'. Maybe it's a young person full of hope in a desolate post - fall world.
