The Mysterious Voice speaks to Vincent and taunts him endlessly in his dreams. He does this while Vincent is on the Landings and during the Nightmare Stages, but is the star of his own show while behind the window of the Confessional. During Vincent's waking hours, the voice is known as The Cryptic Voice.

The voice belongs to Astaroth, a Crowned Prince of Hell, and said to be the patron of inquisitors. He is the being responsible for the creation of Babel (and in extension, the existence of Dumuzid and the Nightmare).

Thomas Mutton says "You'll never see his face, not in a thousand years!" He is probably right.
