There weren't really 'characters' in the traditional sense. But doctors who tried to treat the sick were important. They had no real cure but tried things like bloodletting. Also, the victims of the plague were part of the story.
Well, in the context of the Black Plague story, one could consider the flagellants as a sort of 'character'. These were groups of people who believed that self - flagellation would appease God and stop the plague. They traveled from place to place, causing a stir. Another group would be the merchants. Since the plague spread along trade routes, merchants unknowingly carried the disease, and their actions were part of the complex web of events that made up the Black Plague story.
Maybe there are some heroic space adventurers who are at the center of the story. They could be the ones who first discover the plague among the stars and then take on the task of fighting it. There might also be some alien characters who are either victims of the plague or have some unique knowledge about it.
The character of Judge Coutts is also a main figure. His actions and decisions within the story are significant. He is involved in the events related to the mystery and the relationships between the other characters, and his role helps to drive the plot forward.

The two dogs are the main characters.
There might be a military leader who has to make tough decisions between fighting the war and dealing with the plague situation. Maybe there's also a civilian character who becomes an unlikely hero, helping others to survive the twin disasters of war and plague. It could also have an antagonist, perhaps someone who is spreading the plague deliberately for some malicious purpose.
In the 'Black Sox Story', the main characters were players from the Chicago White Sox. Shoeless Joe Jackson was a prominent one. He was a great player but got caught up in this scandal. There were other players too, and together they formed the group that was involved in the plan to fix the 1919 World Series. Their actions had far - reaching consequences for baseball as a whole, not just for their own careers.
There weren't really specific individual 'characters' in the traditional sense. Instead, the main 'characters' could be seen as the farmers who were affected. They were the ones who had to face the wrath of the dust storms on Black Sunday and in the broader Dust Bowl period. Their families too were part of this, as they all had to endure the hardships together.
