Quest Location
This quest begins at 1759, -1208, 0924 when you activate the teleport at Josiu Shrine.
How to Complete the Quest
The beam of light shines toward a floating device. Use Ultrahand to rotate this device, which will make the curved walkway rotate. Use it to rotate the walkway so it connects the island on the left with the island that the beam is shining at. Then glide to the rocks beneath the island on the left, and use Ascend to go up to the island. From there, you can walk on the curved walkway to reach the crystal connected to the beam. Take it to the island on the left, then climb up onto the higher parts of this island, and glide from there back to the island with the device that rotates the walkway. Rotate it to connect the island with the crystal on it to the island that you are on. Then you can walk on the curved walkway to get the crystal and take it to the shrine.
