Lazulis City in the Reptid's Cave. Zael, Calista and Therius find it when they hear the song of the Sorceress (the theme song of the game). They enter through a portal that opens upon reacting to General Asthar's medal, the Mark of the Outsider, and the Arganan blood flowing through Calista's veins. The chamber holds a tall spiraling staircase, which Zael must descend to reach another portal that leads to the secret of Lazulis Island.
After entering a portal they reach a strange room that warps space and time. There, they meet the ancient Sorceress who summoned the Outsider.
