Yes, it is. Deutschland 86 takes inspiration from real historical events and situations, although it may have some fictional elements added for dramatic effect.
The main theme could be about the African - German experience. It might explore the identity, culture clash, and the sense of belonging of black people in the German context.
I'm not sure exactly who the main characters are without having read the novel closely. But they are likely to be black individuals living in Deutschland who play significant roles in the story's exploration of race, identity, and culture.
The story of 'Deutschland 83' which is based on truth, is centered around the Cold War context. It tells the story of a young man from East Germany who is made to be a spy in the West. It's not just about spying, but also about the clash of ideologies. We see how different the two Germanys were in terms of lifestyle, economy, and military. For example, the fashion, the music, and the technology available in the West were different from what was in the East. And through the eyes of the main character, we get a sense of how complex and dangerous the situation was for those involved in such secret operations.
A really good Casper story could involve Casper helping a group of lost travelers find their way out of a dark and confusing forest. Casper used his knowledge of the spooky area to guide them. He led them through the thick fog and strange noises until they reached safety. Casper's helpfulness in this story makes it a great one.
I'm not sure which specific 'Casper real story' you are referring to. There could be many stories related to something named Casper. It could be about a person named Casper, a Casper in a particular town's history, or perhaps a Casper in a fictional world that has some real - life inspired elements.
