Vessel of Light

From Zelda Wiki.org

The Vessel Of Light is a magical item which usually houses the Tears of Light, however, when the Provinces of Hyrule were pulled into twilight, the Tears of Light were stolen by the Shadow Insects. Thus, the Spirits of Light of each Province asked Link to gather them all in this vessel to restore the area to the light.

There are three provinces where Link must collect the Tears of Light.
-Faron Province - Faron Woods
-Eldin Province - Kakariko Village, Death Mountain
-Lanayru Province - Lake Hylia, Zora's Domain, Upper Zora's River, Hyrule Castle Town
