Timeshift Stone

Timeshift Stones are bluish-purple stones inscribed with a glowing Sheikah Eye. The stones are featured in Skyward Sword uniquely, and are key to many of the puzzles within said game.

Location and Uses
The stones, which were excavated and refined in the Lanayru Mining Facility, are found in the Lanayru Desert region. They are magical objects that can manipulate time. Link can strike the Timeshift Stone to awaken and replenish the land, technology, and its robotic citizens as to how they once were before the carelessness of people of the region caused for the land to wither from its quick depletion of natural resources.
