Shi Kong, the Time-Ruling King from the Space-Time Administration of the Cosmic Sea, detects a serious anomaly in Teyvat's space-time anchor and crosses a rift to arrive at Starsnatch Cliff outside Mondstadt. The compass in his palm reveals the truth hidden in this world: a false starry sky, time flowing at a standstill, fundamental rules altered by an outside force, and an invisible cage encompassing everything.
Beneath the windmills of Mondstadt, the City of Wind, he speaks with Barbatos, the Anemo Archon who calls himself a “wandering bard,” and exposes the helplessness behind the god's disguise. During the night of contracts in Liyue Harbor, he witnesses the thousand-year scheme behind the Geo Archon Morax's apparent death and discovers a space-time anomaly hidden in the accounts of the Wangsheng Funeral Parlor. Beneath the thunder of Inazuma's closed borders, he corrects the temporal turbulence caused by the Vision Hunt Decree, caught between eternity and change. Deep within Sumeru's Tree of Wisdom, he stands alongside Nahida, the Dendro Archon imprisoned for five hundred years, against the Akademiya's forbidden technology that twists the timeline. At last, he reaches the frozen palace of Snezhnaya and uncovers the secret motive behind the Fatui's plan to collect the Gnoses, a motive tied to the collapse of space-time.
He is no savior of Teyvat. The streams of purple-gold light in his hands are meant only to set distorted space-time right, not to rewrite fate itself. Traveling alongside the Traveler Lumine, Paimon, and companions from the seven nations, he witnesses the courage of mortals, the choices of gods, and the sinister schemes of the Abyss. When the Sustainer of Heavenly Principles descends once more, and altered history and imprisoned time begin to turn against the entire world, this visitor from beyond finally understands: his mission is not merely to correct the anchors. It is to let the people of Teyvat find the key to breaking their own cage.
