Myst III: Exile is the third title in the Myst series of graphic adventure puzzle video games. While the preceding games in the series, Myst and Riven, were produced by Cyan Worlds and published by Brøderbund, Exile was developed by Presto Studios and published by Ubisoft. The game was released on four compact discs for both Mac OS and Microsoft Windows on May 8, 2001; versions for the Xbox and PlayStation 2 were released in late 2002. As in previous games, the player assumes the role of the Stranger, a friend of Atrus. A member of the D'ni race, Atrus can create links to other worlds called Ages by writing descriptive books. In Exile, Atrus has written an Age for the D'ni to live on while rebuilding their civilization; it is stolen, however, by a mysterious figure. The Stranger pursues the thief in an attempt to reclaim Atrus' book. The creators of the Myst franchise gave the task of creating the third Myst game to Presto Studios, known for its adventure game series The Journeyman Project. Presto sought to develop a diverse and logical approach to puzzles and Ages, and worked to make the villain sympathetically multifaceted.
