There might be other characters who interact with the man without a heart. For example, there could be a doctor or a healer who tries to understand his condition and help him. This character would play an important role in the story as they try to deal with this unique situation.
There are likely other characters like the military officers or fellow prisoners who play a role in his situation. They are the ones who enforce his punishment of being without a country, and their actions contribute to the development of the story.
The main character is the man without a country, of course. His name was Philip Nolan. He is the central figure around whom the whole story revolves.
The main theme could be about the nature of humanity. Without a heart, it might explore how the man lacks emotions, empathy or a moral compass, which are often associated with the heart symbolically.
