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.

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.
One common theme is power exploration. Fans often write about characters discovering new powers or mastering their existing ones better. For example, in many fanfictions, the main character might find a way to combine different elemental powers.
It's mainly about a story involving magic and family. The protagonist has certain powers related to the wind and there are complex relationships and battles within the story.
