Myst is a franchise centered on a series of adventure video games. The first game in the series, Myst, was released in 1993 by brothers Rand and Robyn Miller and their video game company Cyan, Inc. The first sequel to Myst, Riven, was released in 1997 and was followed by three more direct sequels: Myst III: Exile in 2001, Myst IV: Revelation in 2004, and Myst V: End of Ages in 2005. A spinoff featuring a multiplayer component, Uru: Ages Beyond Myst, was released in 2003 and followed by two expansion packs.

Myst's story concerns an explorer named Atrus who has the ability to write books that serve as links to other worlds, known as Ages. This practice of creating linking books was developed by an ancient civilization known as the D'ni, whose society crumbled after being ravaged by disease. The player takes the role of an unnamed person referred to as the Stranger and assists Atrus by traveling to other Ages and solving puzzles. Over the course of the series, Atrus writes a new Age for the D'ni survivors to live on, and players of the games set the course the civilization will follow.

The brothers developed Myst after producing award-winning games for children. Drawing on childhood stories, the brothers spent months designing the Ages players would investigate. The name Myst came from Jules Verne's novel The Mysterious Island. After Riven was released, Robyn left Cyan to pursue other projects, and Cyan began developing Uru; developers Presto Studios and Ubisoft created Exile and Revelation before Cyan returned to complete the series with End of Ages. Myst and its sequels were critical and commercial successes, selling more than twelve million copies; the games drove sales of personal computers and CD-ROM drives as well as attracting casual gamers with its nonviolent, methodical gameplay. The video games' success has led to three published novels in addition to soundtracks, a comic series, and television and movie pitches.
