Riven, Player Character

Having been rescued from the machinations 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 and linked together by special books, Riven takes place almost entirely on the eponymous Age of Riven, a world slowly falling apart due to Gehn's rule, and his tampering with the Age.
