There's Christopher Tietjens, who stands as a symbol of the traditional upper - class values. He has to deal with his wife Sylvia, who is a rather complex and often difficult character. And then there's Valentine Wannop. She is a young woman who has a deep connection with Christopher. There are also other characters like General Campion who are important in the context of the story, especially in relation to Christopher's military and social experiences.
Christopher Tietjens is key. He is a man of honor and duty, and his internal struggles form a major part of the narrative. Sylvia Tietjens, his wife, is a character full of contradictions. She is both alluring and troublesome. Valentine Wannop plays an important role as well. She is in love with Christopher and their relationship is tested by the social and personal circumstances in the novel.
Margaret Schlegel is very important. She is intelligent and tries to bridge the gap between different social classes. Helen Schlegel is another key character, she is more impulsive than Margaret. Mr. Wilcox is also important as he represents the upper - class values and has a complex relationship with the Schlegel sisters.
The Overlords are crucial characters. They are the alien beings who come to Earth and take over. Their appearance and actions drive the entire plot. Another important character is Karellen, an Overlord who has a significant role in interacting with humans. He is often the face of the alien rule and his decisions impact the future of humanity.
Captain Stanhope is an important character. He is a complex figure, a brave leader but also haunted by the war and his own inner demons.
Yuichiro Hyakuya is very important. He is a determined and vengeful character, driven by the need to take revenge on vampires for his family's death. Mikaela Hyakuya is another key character. He has a complex relationship with Yuichiro. Guren Ichinose also plays a significant role. He is a leader figure among the humans and has his own secrets and motives.
Alice herself is surely an important character at the end. She might be the central figure around which the final events of the novel revolve. There could also be a mentor - like character who helps her reach a certain conclusion or understanding at the end.
I'm not entirely sure about all the main characters, but there are some key ones involved in the judgment process.
The main themes include the transformation of society. Parade's End reflects how the traditional upper - class values are being challenged. Love is also a major theme. The love affairs in the novel are not straightforward; they are intertwined with the characters' social positions. And the theme of war is there too. It shows how war affects the characters' lives, both physically and psychologically, and how it contributes to the overall change in the social fabric.
I really can't say exactly who the important characters are in 'the end of the circle robotech novel' without reading it. But in the Robotech universe, there are often characters who are in charge of the mecha units. They could be important in the end part, leading their teams in the final battles or negotiations. There might also be some scientist characters who play a crucial role if the end involves some technological revelations or solutions.
John is obviously one of the most important characters. He's right there in the title. His friend, whose name I can't recall at the moment but is also central to the story. And then there are all those strange creatures and entities that they interact with. They play important roles in creating the crazy and dangerous situations that John and his friend have to face.
The mother is an important character. Her love for her son and her determination to find him drive much of the story. The son who goes missing is also key, even though he's not always present physically. His absence shapes the actions and emotions of the other characters.
