I don't know as I haven't read it, so I can't tell who the main characters are.
The empress is the obvious main character in the 'empress neverending story'. However, there could be a whole cast of supporting characters. There could be a wise old wizard or sorceress who gives the empress advice. There might be a group of rebels who oppose the empress's rule for various reasons, adding conflict to the story. And don't forget about family members. Maybe the empress has a sister or a mother who play important roles in the story, either supporting or challenging her. Also, there could be foreign ambassadors or invaders who interact with the empress and shape the events of the neverending story.
The two swindlers are important characters. They are the ones who deceive the empress with their false claim of making the most magnificent clothes.
The main characters are the empress (or emperor in some versions), the two swindlers who claim to make the magical clothes, and the little boy. The empress/emperor is vain and easily deceived. The swindlers are clever tricksters, and the little boy is the voice of truth.
Well, the empress is bound to be a central character. Then, depending on the nature of the story, there could be her political allies, those who help her ascend the throne or maintain her rule. There might also be her enemies, whether they are from within her own court or from rival empires. Additionally, if the series delves into her personal life, there could be childhood friends or mentors who shape her character.
Well, without more context, it could be anyone. It might be a young couple from different social classes, like Romeo and Juliet.
In 'the last empress novel', the main character is the empress, no doubt. She is likely to be a complex figure, with her own desires, fears, and ambitions. Alongside her, there could be powerful ministers who either support or oppose her. There might be a foreign diplomat or two if the story involves international relations. And don't forget about the servants in the palace, some of whom could be very close to the empress and be privy to her secrets, and they too could be important characters in the novel.
The main characters in the 'black empress novel' are difficult to determine without reading it. But we can assume that aside from the black empress, there could be a love interest for her, or rivals vying for her throne. There may also be some characters from different social classes, like a poor peasant who somehow gets involved in the affairs of the empress, or a noble knight who has sworn loyalty to her, and these characters' fates could be intertwined with the empress' story.
Since we don't have much information about the '1960 love story', it's hard to say who the main characters are. They could be ordinary people, like a factory worker and a schoolteacher.
I'm not sure as the title doesn't give away the main characters directly. But it could be a couple who are caught up in the events of 1984 while experiencing love.
I'm not sure as I don't have specific information about this. It could be athletes or people related to the sports world who are central to the love story.
