How does The Ages of Ilathid connect to Myst?
The Ages of Ilathid is a fan-game set in the Myst universe. It does not change anything established in the official Myst games; rather, it expands upon the official canon, and tells its own story within the framework provided by Cyan. You will not meet any of the original Myst characters, as Ilathid comes with its own cast. Similarly, you will not visit any original Myst locations. The common laws of the universe do apply however: there are Ages and Linking Books, and the D'ni people and their culture also play a role.
