Identity: One of the four Shades (Four Shadows) created directly by the creator god 'Phanes (The Primordial One)' from his own shining shadows.

Aliases: 「Archon of Death」, Tuonetar, Mistress of the Underworld. Governing Authority: Defining the concept of death, bestowing death, bestowing immortality, and controlling souls and Ley Lines.

Appearance: Possesses a somewhat terrifying look, wearing primarily a black dress and body stockings. She uses an arch-shaped symbol with a giant red eye on her back as her emblem. She takes the form of a woman.

Key Features and History: Authority to Define Death and Immortality: She manages the 'Rules of Death' itself rather than simple killing. While she can bring death to living beings, paradoxically, she can also inflict the 'Curse of Immortality' to prevent them from dying.

Khaenri'ah's Curse of Immortality: She is the one who, under the orders of the Heavenly Principles, inflicted the curse of immortality on the pure-blooded people of Khaenri'ah during the cataclysm 500 years ago. Due to this curse, individuals like Pierro of the Fatui and Clothar of the Abyss Order suffer the pain of eternal erosion, which became the catalyst for the formation of the major antagonist factions in Genshin Impact.

Natlan's Salvation and Rules (Ode to Resurrection): In the past, she lent a portion of heavenly authority through a contract with Xbalanque, the first Pyro Archon of Natlan. Based on this, Natlan's unique soul and resurrection systems, 'Ode to Resurrection' and the 'Pilgrimage of the Return of the Sacred Flame', were established.

Mechanical and Cold Pragmatism: She is not swayed by the sacrifices or emotions of mortals and exhibits a mechanical side that strictly values the balance of 'Heavenly Rules' and 'Price.'

Personality and Stance: Unlike other Shades who are missing (Asmoday), lack motivation (Istaroth), or are immersed in personal research (Rhinedottir), she is the divinity who acts most faithfully to the orders of the Heavenly Principles and her primary duty (maintaining the order of death). Since she acts to maintain the divine order of the Heavenly Principles, she is inevitably in a hostile relationship with the Traveler and the Snezhnaya/Fatui factions.
