Claim: Unseen character (not a ghost character, someone who doesnt speak in plays) are causal figures included in dramatic works but are seen as more powerful because they are only known by inference.
Evidence: An unseen character in theatre, comics, film, or television, or silent character in radio or literature, is a character that is mentioned but not directly known to the audience, but who advances the action of the plot in a significant way, and whose absence enhances their effect on the plot. It is a character who is mentioned as appearing on stage, but who does not do anything, and who seems to have no purpose.
