The Throat of the World is a quest available in The Elder Scrolls V: Skyrim. During this quest the Greybeards teach the Dragonborn all three words of the Clear Skies shout, Lok (Sky), Vah (Spring), and Koor (Summer) in order to reach the summit of the mountain. The Dragonborn also learns a word of the Fire Breath shout (the exact word depends on the words already known.)
