I don't know the main characters in this novel as I haven't read it. But they could be members of the imperial family, servants, or courtiers.
Since it's called the 'imperial bedroom novel', the main characters might include an emperor or empress. There could also be trusted advisors or lovers who have access to this private space and play important roles in the story. Maybe there are also some maids or guards who are privy to the happenings in the imperial bedroom and contribute to the plot in some way.
The main characters could be a variety of people. There might be a young prince or princess who is coming of age and their experiences in the imperial bedroom are central to the story. It could also feature a power - hungry noble who tries to manipulate the situation in the imperial bedroom for their own gain. And of course, there could be a wise old servant who has seen many things in the imperial bedroom over the years and whose insights are crucial to the development of the plot.
The main theme might be related to the secrets and intrigues that occur within the imperial bedroom. It could involve political plots, romantic affairs, or family power struggles that center around this private space.
As I haven't read the novel, I can't say for sure. But I would assume the abandoned princess is a main character. There might also be characters like servants who knew her before she was abandoned, or perhaps people who play a role in her new life after abandonment.
Since I haven't read it, I can't say for sure. But I assume the abandoned princess is one of the main characters. There might also be a servant or a friend who helps her in the story, or perhaps an antagonist like the person who ordered her abandonment.
Perhaps there is a best friend who tries to reach out to the dejected daughter but is constantly shut out. This friend could play an important role in trying to understand what's going on with the daughter and why she is so withdrawn in her secret bedroom. Another character could be a sibling who either teases the daughter, adding to her dejection, or is sympathetic and tries to help.
Obviously, the dejected royal daughter would be one of the main characters. She is the center of the story as it's her secret bedroom. There could also be her maidservant who might be the only one aware of her true feelings and the things she does in her secret bedroom.
The main characters in the 'imperial commando novel' may include not only the imperial commandos but also those who interact with them, like their superiors in the imperial military hierarchy. There could be a mentor - like figure for the commandos, someone who has been through many battles and imparts wisdom to the younger commandos. And perhaps there are some antagonists, either from rival military factions or from groups that oppose the imperial regime, which the commandos have to face off against.
Probably the imperial doctress is one of the main characters. In addition, there could be her mentors or colleagues in the medical field within the imperial court. And perhaps there are some patients from the imperial family, such as the empress or a prince, who play significant roles in the story as well.
I'm not familiar with all the characters in 'the imperial coroner novel', but surely the titular imperial coroner is a main character. There could be other important figures such as the emperor or empress, if the plot involves high - level political matters. Also, perhaps there are servants or guards who play significant roles in helping or hindering the coroner's investigations. Maybe there is a love interest for the coroner as well, which could add a romantic sub - plot to the story.
I don't know the exact main characters as I'm not familiar with this novel. But it's likely that the imperial consort herself is a main character. There may also be the emperor and perhaps some court ladies or eunuchs who play important roles.
The central character is the imperial knight freeblade, of course. But there could be a whole cast of characters around them. There might be other knights who don't understand the freeblade's choice and see them as an outcast. There could be a group of imperial guardsmen who end up fighting alongside the freeblade. And on the enemy side, there may be powerful psykers or daemonic entities that the freeblade must battle against.
