A puzzle adventure game set immediately after the events of Myst. Having been rescued from the efforts of his sons, the main non-player protagonist Atrus enlists the help of the player character to free his wife from his power-hungry father Gehn. Unlike Myst, which took place on several worlds known as Ages, linked together by special books, Riven takes place almost entirely on the Age of Riven, a world slowly falling apart due to Gehn's destructive rule.
