The Goddess Statue in the Temple of Time Ruins on the Great Plateau is calling for help.
Quest Location
You can begin this quest by talking to the Goddess statue in the Temple of Time Ruins on the Great Plateau.
Trapped Beneath the Water
Go to the northeast side of the Great Plateau and glide down to Hyrule Field, at the intersection of the road that goes northeast between the Forest of Time and Lake Kolomo, and the road that goes along the north side of the Great Plateau. At this intersection, look at the Great Plateau and you will see some stones in the gate. There is some water leaking out of these stones. Use a bomb or a heavy weapon or some other method to destroy those stones. The water will drain out.
Talk to the Statue
Now you can go back to the Temple of Time Ruins on the Great Plateau and talk to the Goddess statue to find out that there are four eyes, one near each chasm on the Great Plateau.
Transport the Eyes
Go to each of the four chasms on the Great Plateau and look for the eye near each one. The eye might be under rocks or ice. Drop the eye into the nearby chasm, then fall into the chasm. At the bottom, look for things like mine carts and Zonai Devices that will allow you to transport the eye to the Great Abandoned Central Mine. There is a door in the southwest side of the Great Abandoned Central Mine that leads to a Bargainer Statue that is missing its eyes. Use Ultrahand to put the eye into one of the empty spaces.
Quest Reward
After you have placed all four eyes, the Bargainer Statue gives you a choice of a Heart Container or Stamina Vessel. You can also now purchase the Tunic of Memories from this statue and the other Bargainer Statues throughout the Depths.
