Time is falling apart in Teyvat. Ghost ships trapped in a loop, ancient relics brought back to life, Abyssal minions moving in fits and starts... A disaster known as “Temporal Entropy” tears apart the very fabric of reality. The alien Traveler, Ying, is led by the mysterious scholar Xuanyuan toward a forbidden divine artifact said to reverse time: the “Hourglass of Time.”
Deep within the ancient ruins of the Chasm, they confront distortions in the flow of time and echoes of history. The instant they seize the core fragment, the “Red Sand Core,” the Abyss's main forces attack, and an uncontrollable surge of spacetime power hurls Ying's consciousness back three days!
Armed with memories of the future and the fragment's remnants, Ying becomes a “prophet.” She must find Xuanyuan again, now afflicted with the curse of sandification, and convince him to face certain death alongside her. Together, they must rewrite their doomed ending while contending with even more powerful foes and sinister traps in time.
Yet the shadow of “Chaos” in the Abyss's whispers looms over all, the Heavenly Principles' cold gaze prickles at their backs, and the whereabouts of Ying's brother, Kong, remain a mystery. From the mining depths of Liyue to the ends of the seven nations, all the way to a dying mirror world, Ying and Xuanyuan's journey is a desperate race against the raging tide of time, and the last stand to stop the “Void Realm” from devouring Teyvat.
Can turning back time avert the end? Traveler, find a way to survive before the sands of time run out!
