Maybe there are voices from different historical periods who are reflecting on the possibility of a world without humans. These voices could be from ancient philosophers or modern environmentalists, all contributing to the overall narrative of the novel without being traditional characters.
One of the main themes could be environmental change. The novel might explore how the world would transform without human presence in terms of nature reclaiming spaces. For example, cities would become overgrown with vegetation.
It's likely that there are characters representing different social classes. There could be a noble figure who has to deal with the responsibilities of his or her position, and a commoner who dreams of a better life. These characters would interact and their stories would unfold throughout the 'world without end' setting.
I'm not sure specifically as I haven't read this novel in detail. But probably there would be female leaders who emerge in this new world. They could be the ones guiding the other women through the chaos of suddenly being in a male - less world.
I'm not entirely sure as I haven't read it recently, but usually there would be a protagonist who is likely to be a defender of the world without thieves concept, and perhaps an antagonist who challenges this idea.
Since I haven't read the novel, I can't tell you exactly. But generally, there could be characters who were close to 'him' like friends or family members. There might also be characters who are affected by the changes in the world because of his absence.
There would likely be characters like Lois Lane. She might be trying to find out what happened to Superman. Also, Lex Luthor could be a main character as he would take advantage of Superman's absence. Other heroes such as Batman or Wonder Woman could also be main characters as they deal with the situation in the world without Superman.
Some of the main characters include Merthin, a builder with great vision. And Caris, a strong - willed woman. There is also Gwenda, a peasant girl.
Since I'm not familiar with this graphic novel, it's difficult to say. But it might have a group of characters. There could be a young and curious protagonist who discovers something strange about their world, and there might be some wise old characters who guide them on their journey.
Maybe there is a character who is on a quest to find out what caused the world to become lifeless. This character could be a scientist or a philosopher type, constantly searching for answers and encountering various obstacles along the way.
I'm not sure as I haven't read it. But they could be ordinary people trying to adapt to a world without guns, or perhaps some law - enforcers who now have different roles.
