To understand the cosmological stature of the Moon Sisters within Genshin Impact, one must look back to the era between the Primordial One's creation of the Human Realm and the war against the Second Who Came. Recorded in classic literary archives such as *Moonlit Bamboo Forest*, *Heart's Desire*, *Records of Jueyun*, and the prophecies of Nod-Krai, the Moon Sisters were not mortal Vision-bearers or regional Archons, but celestial deities of the Silver Palace who embodied the three ancient moons of Teyvat: the Eternal Moon (永恒之月), the Iridescent Moon (虹月, whose shattered remnant became the Crimson Moon), and the Frost Moon (霜月).

In the poetic cosmology of Teyvat, the three names of the Moon Sisters—Aria, Sonnet, and Canon—correspond to three classical forms of musical and lyrical composition, reflecting their ancient harmony with the Seelie race, who sang ballads in the courts of the gods. Because the Moon Sisters shared a single heart of devotion toward the Morning Stars of daybreak and governed the boundary between the false sky and the dark realm, their fall fundamentally altered the spiritual laws of Teyvat, stripping the Seelie of their forms and birthing the lunar curses of Khaenri'ah and Nod-Krai.

In the golden dawn of antiquity, the Moon Sisters—Aria, Sonnet, and Canon—presided over the night from their celestial citadel, the Silver Palace. Every ten days, one of the Moon Sisters would pass the reins of their silver chariot to the next, ensuring that Teyvat's nights were bathed in gentle, rhythmic radiance. As daughters of prose and song, the Moon Sisters loved the Morning Stars above and walked in friendship with the ancient Seelie ancestors, witnessing the fateful union between a Seelie maiden and a traveler from afarInside the Moonlit Bamboo Forest.

Thirty days after that forbidden union, disaster struck the heavens during the Great War of Vengeance when the Second Who Came clashed with the Heavenly Principles. As the pillars of the world cracked and the sky burned, truth and illusion became inverted: the Moon Sisters were poisoned by grief, deception, and cosmic madness, ultimately drawing their blades against one another in a fratricidal calamity.

In the aftermath of the war, two of the Moon Sisters perished completely, their lunar bodies shattering into fine cosmic dust: the Eternal Moon fell and caused torrential upheavals, while the Iridescent Moon's shadow sank into the Abyssal void to become the ominous Crimson Moon revered by Khaenri'ah's first dynasty. The third sister—the Frost Moon—was left as a cold, lifeless corpse suspended in Teyvat's night sky, her lingering pure light preserved by the Frostmoon Scions in the northern borderlands of Nod-Krai.
