This device conveys riders through a maze of caverns to the cavern with the Myst Linking Book on the Selenitic Age. Buttons on the control panel send it forward to the next junction, back to the last junction, or rotate it left or right at each junction station.


According to Chuck Carter of Cyan, the shape of the Mazerunner was inspired by the "Flounder" character of "The Little Mermaid" while viewing it with his children.
