Riven: The Sequel to Myst is a graphic adventure puzzle game developed by Cyan and released in 1997. It continues the story of Myst, following the player’s journey to rescue Atrus’s wife, Catherine, from a decaying world. The game features pre-rendered environments with complex, interconnected puzzles and minimal direct guidance.

Its visuals, sound design, and world-building were praised for their depth and realism.

Riven expanded on Myst’s narrative and gameplay scale, becoming one of the most acclaimed adventure games of its time.

After the Stranger has rescued Atrus, the master of "linking books", from the imprisonment caused by his sons, a new task awaits the hero. Atrus's wife, Catherine, has been taken by Gehn, his own father. Gehn has appointed himself as the one to rule the Age of Riven, and has driven his world to collapse. Now he holds Catherine hostage on Riven, hoping that his son will restore the book link to the Age and free him from there. The Stranger is requested by Atrus to travel to Riven and find a way to rescue Catherine.
