"Before Myst III:Exile, Atrus started searching for D'ni survivors and Linking Books in the Old D'ni City and Ages. As he found them, more helped with the enormous task. You are one of these survivors. Lost from your team, you enter an old crack in a stone wall to find yourself in a ruined tunnel. However, the tunnel entrance collapses behind you as you enter, leaving you stranded and alone, with no other hope but to find an alternate way out."
