Follow the Sheikah Slate

"" is a Main Quest in.

Overview
Link obtains the Quest shortly after a mysterious voice awakens him and urges him to leave the Shrine of Resurrection to restore the light to Hyrule. to explore the Great Plateau. The Quest is initiated when the mysterious voice calls out to him once more. The voice instructs Link to head towards the destination marked on the Sheikah Slate's Map, which denotes the location of the Great Plateau Tower.

Upon reaching the buried remains of the Great Plateau Tower, Link must activate it by placing the Sheikah Slate into the pedestal. In doing so, Link causes the Great Plateau Tower to shoot upwards out of the ground that once held it. This causes a simultaneous reaction among all of the other Sheikah Towers scattered across Hyrule, forcing them to rise as well. At this same exact moment that the Sheikah Towers collectively ascend, Ancient Shrines across Hyrule begin to glow an orange light, acting as a sort of beacon to allow Link to locate them from a distance. When Link regains his composure following his rapid ascension, the Great Plateau Tower begins to distill regional information on the Great Plateau in the form of a tear drop, which splashes onto the Sheikah Slate and updates its Map with landmarks and geographical data.

The voice calls out to Link again before Link begins to leave the Tower, urging him to remember the events leading up to his awakening. However, the Calamity Ganon interrupts her and begins to swirl around Hyrule Castle before being driven back by a white light emanating from the Castle. The voice warns Link that when the Calamity Ganon regains its full strength, she will no longer be able to contain it. This completes the Quest, allowing Link to descend the Great Plateau Tower and speak to the Old Man, who tasks him with the next Main Quest, "The Isolated Plateau".
