This optional side-quest can be obtained after gaining access to the Gate of the Sun (Chapter 10). Fly all the way to the top-right of the map (after exiting the elevator) and you will encounter a white elemental. You task to is help the elemental find his friends.

Remember those weird looking shrines you might have encountered along the way? That's where the other elementals are located. There are six shrines throughout Lemuria so let's get moving!

After taking the quest from the elemental, head left from your current position and head towards the ground while passing two waterfalls. The first shrine is located to the right of the giant electrocuting crystal.



Now take the elevator back up to the Piscean Village. Keep heading left while hovering just above the water. You'll soon reach the second shrine.



The remaining shrines will require you to fast travel.

Fast travel back to the Old Monastery and exit the building through roof. Follow the trees until there is room for you to fly downward. You'll see the shrine on the top level of the ruins. If you've flown past the balloon houses, you've overshot the shrine location.

Fast travel to the Capilli Village and head back to the outer (first) area of the village. Keep heading right until you're out of the village. Continue heading right down the road and you'll soon bump into the shrine.

Fast travel to the Town of the Bolmus Populi and fly right to exit the town. Keep heading right until the second waterfall stops your screen from scrolling any further. This is a sign to head downward towards the ground. Keep heading right past the lone Populi campsite and the shrine will be in sight.

The location of this shrine is slightly confusing. I have provided additional screenshots to help.

Fast travel to the Temple of the Moon but don't enter the doors. Instead, fly downward through the narrow passageway. Beware of the sharp fence-like structures. Keep heading down past the two fire-wraiths into yet another narrow passageway. (Screenshow below shows the second fire-wraith and the passageway is below Aurora.)



Keep heading down this second narrow passageway. Beware of strong winds when exiting. Directly below the exit of this second passageway is a floating island with one of those archer sentries. The island directly to the right of him is where the shrine is located.

After visiting all six shrines, head back to the elemental at the Gate of the Sun. Talk to him to complete the quest.



For your troubles, he rewards you with 3x Faceted Spinels which does the following when equipped.



In case you're wondering how Spinels are created, you will need to craft an Onyx with a Diamond.
