The person who is telling the story is often called the narrator. It could be the main character in a first - person narrative, sharing their own experiences directly. For example, in 'The Catcher in the Rye', Holden Caulfield is the narrator, and we see the story unfold through his eyes.
We can learn about the events that are taking place in the story. The narrator will describe what is happening, who is involved, and where it is all going on.
Power is a major theme. Two Lucifers would bring a lot of power into one story, and it can be about who has more power or how they use their power together.
In the world of 'lucifer meets lucifer fanfiction', a common plot could involve a clash of egos. When two such powerful and complex characters meet, there's bound to be conflict.
