The term "character roster" refers to a list or group of characters in a story, play, movie, television show, or other form of entertainment. It typically includes information about each character such as their name, role, and any relevant details that help the audience understand who they are and what part they play within the narrative. The character roster can also include descriptions of how characters interact with one another, providing insight into relationships between them and helping to build a more complete picture of the story's world.
