I'm not sure as I haven't read the novel specifically. But in a typical spy novel, there would likely be a main spy character. This person would be intelligent, resourceful and have some sort of special skills or knowledge. There might also be a villain, someone who is working against the interests of the main character and perhaps has their own eschatological - related goals.
Since I haven't read the book, it's hard to say exactly. However, in spy novels, there are often agents who are the central figures. They could be working for a government agency or an independent organization. In the context of an eschatological spy novel, there may be a character who has some sort of prophetic knowledge or is trying to prevent a cataclysmic event. And of course, there would probably be supporting characters like the spy's handlers or informants.
One main theme could be the concept of eschatology, which might involve ideas about the end of times or a major upheaval. In a spy novel context, it could be related to the potential end of a certain regime or power structure that the spy is involved in. Another theme might be the internal 'tremor of intent' within the characters, like the moral and ethical dilemmas they face while carrying out their espionage tasks.
I'm not sure specifically as it depends on the particular spy camp novel. But usually there are trainees, instructors, and maybe some villainous spies.
In the 'spy classroom novel', the main characters are likely to be the trainees in the spy classroom. Some may be the best in combat, some might be excellent at decrypting codes. There could also be a teacher or instructor figure who guides them through their training and missions. These characters interact with each other, and their relationships play an important role in the story.
Since it's a 'spy kyoushitsu novel', the main characters might include a young and intelligent student who discovers the world of spying within the classroom. There could also be a mysterious figure, perhaps a janitor or a visiting lecturer, who is actually a high - ranking spy guiding the protagonist. And of course, there may be some antagonists like other spies from rival organizations trying to disrupt the operations happening in the classroom.
In a 'spy ninja novel', the main character is likely to be the spy ninja. This character would be the focus of the story, with their actions driving the plot forward. There could also be other important characters, such as the villain they are up against. This villain might be a powerful criminal or a rival spy. Additionally, there could be supporting characters like the spy ninja's friends or allies from their spy or ninja community. They might provide help, information, or be in need of rescue at some point in the story.
Often in Mathews' spy novels, there could be a female character who is just as important as the male ones. She might be a tech - savvy agent who can hack into any system. There could also be an older, more experienced spy who acts as a mentor to the younger agents in the story.
I don't know as I haven't read it. Maybe there's a spy named after a salamander or someone who has a special relationship with salamanders.
I don't know the main characters in 'the spike spy novel' as I haven't read it. It could have a suave and intelligent spy as the protagonist, perhaps named after the'spike' or associated with it in some way.
Without having read 'the sparrow spy novel', we can only guess. The main character is likely the sparrow, who could be a complex character with a mysterious past. There may be a love interest, perhaps another spy or a civilian who gets involved in the sparrow's dangerous world. And of course, there would be the sparrow's superiors in the spy agency, who have their own agendas and may influence the sparrow's actions throughout the story.
Since I don't know the specific'spy room novel', it's hard to say. But usually, there would be spies, of course. Maybe an experienced spy who is the leader in the room, and a novice spy who is learning the ropes.
