The Stargazer, once known as Edwin, is a monster found in Apartment 31. Its transformation has rendered it invisible except in the darkness. It emits growling sounds as it invisibly follows Sam through its apartment, opening and closing doors, but will not venture into the living meat rooms in the dark version. Edwin at one time ran a photographic equipment lending business from his apartment, including at least three telescopes, specialized camera lenses, and a projector. He worked with the Astronomers when they discovered the Visitor months before the beginning of the game.
