As the Traveler, you do not possess a Vision to call your own, instead, you rely on the Statues of the Seven as the source of your elemental powers. When you, the Traveler, resonate with one of these monumental statues, you will gain the ability to use the respective element that statue is associated with.
Statues of the Seven are built and fashioned in the image of their respective Archon. As an example, the Statues of the Seven in Mondstadt resemble the Anemo Archon, Barbatos. This same principle applies to Liyue and all the other nations as well. The first statue ever encountered in the game is the one in Starfell Lake, which Paimon leads you to at the very beginning of your journey.
While you journey in Teyvat, there will be times where you will come across little substances known as “Oculi '' (Oculus for singular). These Oculi, after a certain amount has been gathered, can provide blessings from the Statues in exchange for returning the power that they have lost over the millenia.
Mondstadt:
“Monumental stone statues that watch over the whole of Teyvat. Legends say they were sculpted in the images of The Seven who sustain this world. Travelers would pray for the statue's protection should they come across one, while it silently anticipates the arrival of a noble soul…”
Liyue:
“A monumental stone statue that watches over Liyue. Legends say it was sculpted in the image of the Geo Archon. Despite its bustling harbour which attracts many traders, Liyue's history is calm and peaceful like its archon.”
Inazuma:
“Large statues found scattered across the islands of Inazuma. Many believe that the statues were carved in the image of the Electro Archon. "Glory to the Shogun and her everlasting reign!" Just like this statue, the islands of Inazuma may very well transcend the ages in their pursuit of Eternity.”
Sumeru:
“A large stone statue that stands in various locations in Sumeru. It it said to have been carved in the image of the Dendro Archon. As it is said, "There is nothing new under the sun." The ancient realm of wisdom has weathered calamity just like the statues gaze down at the cycles of rebirth.
