The Oracle is the third episode out of four in the Cognition adventure game series. The story picks up right after the second episode, as Erica reaches the Enthon Tower where Joey was thrown off the top floor. The episode reveals the identity of both The Oracle and the Cain Killer and explains their motivations behind the murders.

For the first time in the series, players can control a second character, Cordelia. Following her storyline, the player learns what happened to her brothers, Max and Keith.
