One of the main themes could be isolation. The characters might be isolated from their former lives or society in some way. Another theme could be self - discovery as they navigate through the events in the novel. And perhaps a theme of change, as leaving the world behind implies a significant shift in their existence.
I'm not entirely sure without reading the novel, but usually in such a story, there might be a protagonist who initiates the act of leaving the world behind. There could also be some supporting characters like a friend or a family member who either joins in or tries to stop the main character.
The themes include isolation and the search for connection. The characters are isolated from their familiar surroundings, and they struggle to find new connections with others in the midst of the upheaval. Also, there's a theme of survival. They have to figure out how to survive in a world that has suddenly become very different and dangerous.
The main themes include despair and the search for meaning. In the 'Leaving Las Vegas' novel, the character's downward spiral is a sign of his deep - seated despair. He seems to have given up on life and is using Las Vegas as a place to end it. At the same time, it can be seen as a search for some kind of meaning in his final days, even if it's a perverse one through excessive drinking. Also, the theme of the relationship between the individual and the city is prominent. Las Vegas is almost like a character itself, with its own rules and allure that the protagonist both succumbs to and battles against.
Well, it could be about change. When things are left behind, it implies that there has been a shift or transformation. Maybe the story focuses on how the characters deal with this new situation after being left. For example, they might have to adapt to a new environment or way of life.
The main theme could be about the passage of time and how it affects relationships and personal growth.
Since I haven't read this particular fanfiction, it's hard to say for sure. But it could be an original character created by the fanfic author who decides to leave everything behind. Or it could be a well - known character like Harry Potter himself, if the story takes a different turn where he wants to escape his fame and the burdens that come with it.
The main themes may include the exploration of the unknown. In this 'world of immortals novel', the immortal world is full of mysteries. Characters may constantly explore new regions, magic, or abilities, which represents humanity's curiosity for the unknown. Also, the theme of friendship and loyalty could be important. Immortals may form alliances and the bonds between them are tested through different events.
One of the main themes could be the relationship between home and the wider world. It might explore how the values and cultures within a home environment interact with the broader global context.
One of the main themes might be power dynamics among men. In the 'world of men novel', it could show how men compete for power, whether it's in a workplace, a social group or within a family. Another theme could be brotherhood. It might depict how men support or betray each other. And also, the theme of self - discovery for men could be present, as they figure out their place in the world.
One possible theme could be the struggle of the individual against society. The 'weight of the world' in the title might suggest the burdens that characters face due to social norms and expectations.
