Keep traveling forward to find a chest (Potion), then return to the split and take the other path to travel deeper into the dungeon. Follow this path until you reach a path that leads off into a small chamber with a chest (Spell Cure). After this, continue to follow the path to a set of stairs.

In the next cave go down-left for a chest (500 gil). Then go to the skull at the top-right corner. Zoom in and you see that it shines. Activate it and the wall will upon up. Continue along the path and enter the next room. A cutscene will play and Princess Sara will join the party. Continue into the next room. With you can speak with Princess Sara if you wish to do.

Go along the path until you get to crossroads and take the path leading down for a chest (Antarctic Wind) and then take the path going up. After you get to the large chamber, go down and get the chest (Eye Drops) then go up slightly and take the path going left. The path will turn down into a large chamber with another path leading to the right. It is advisable to heal your party members as the Djinn is right around the corner.
