Pierrot and Ronova

Main character traits
Restraint and rationality. Unlike other Shadows, Ronova is not prone to frivolous toying with the lives of mortals. She strictly adheres to the "rules" of the Celestial Order and frowns upon attempts to violate them (though there are exceptions).
Cruelty and impartiality. Ronova acts as a punishing force, maintaining the balance of life and death. She can both grant power (as with the first Pyro Archon Xbalanque) and punish by depriving one of death (the curse of immortality for purebloods of Kaenri'ah). For this, she has been nicknamed the "divine executioner."
Contradiction after punishment. After the Primordial condemned her for exceeding her authority (assisting in the creation of the Night Realm in Natlan), Ronova became more withdrawn and indifferent to the fates of mortals. However, she did not abandon her influence on the world, acting secretly and through deals.
Empathy. Despite her role as a punishing deity, Ronova displays more humanity and compassion for people than other Shadows. She is able to find loopholes in the rules to avoid undermining the foundations of the world and support Celestia's priorities.
Age: About 6000 years old, looks like a girl of 20-25 years old
Powers and abilities
Power over death
As the Mistress of Death, Ronova governs the laws of death in Teyvat. Her power allows her to determine how death will affect a specific being, and in certain cases, to completely eliminate the possibility of natural death.
The most widespread known example of this is the curse of immortality upon the purebred inhabitants of Kaenri'ah. In this case, the punishment was not immediate death, but the impossibility of death: the cursed continued to exist for centuries, unable to die in the normal way.
The conditions and price of her power
Ronova's power can be granted to another being under certain conditions. In the contract with Xbalanque, the use of her power was bound by an inevitable price—the death of whoever would use it.

Ronova, also known to the Children of the Frost Moon as Tuonetar, is one of the Four Shadows of the Celestial Order and the deity who presides over the laws of death in Teyvat.
Her primary known title is Mistress of Death. In the ancient cult of the far north, she was revered as Tuonetar, Mother of the Underworld. Ronova existed long before the modern system of the Seven Archons and, for millennia, rarely manifested directly.
Appearance
In her human form, Ronova appears as a tall woman with pale skin, long, thick white hair, and golden eyes with pupils shaped like a seven-petaled flower.
Her outfit is predominantly black, gray, and red. She wears a black, translucent bodysuit under a black, strapless dress. The front of the skirt is open, revealing her legs. Two triquetras (symbols associated with Ronova) are positioned on the sides of the dress, over a pleated, translucent gray skirt that falls to the ground. The back of the skirt is decorated with black feathers with dark red trim.
Accessories include:
black opera gloves;
a pair of red eye-shaped ornaments on either side of the hair;
black high-heeled shoes;
a black sheer veil attached to the back of the hair;
a pair of upward-curved dark red wings with eye-shaped holes.
Ronova's hands are almost black, with red eye-shaped designs painted on them. When concentrating her power, her nails appear elongated.
True form
When Ronova uses the crimson rift in Teyvat's skies to observe the world, she manifests as six eyes: two on the right, three on the left, and a larger central one. This crimson energy is considered a manifestation of her power.
Symbolism
Elements of her appearance carry a certain meaning:
Wings with eyes symbolize constant observation of the balance of life and death.
The grey veil, reminiscent of a mourning veil, emphasizes the connection with the inevitable

Main character traits
Cold pragmatism. He evaluates people and Harbingers solely in terms of their usefulness in achieving the Queen's goals. His decisions are carefully considered and calculated over years.
Reserved and secretive, Piero rarely displays emotion, even in conflict situations. He's not inclined to share his personal experiences with others, making him an enigmatic figure for other Harbingers.
Decisiveness and conviction. He has no doubts about his own righteousness and is willing to make any sacrifice to oppose the divine order. Yet, he is not reckless and cruel—he acts with cold calculation.
Recognizing talent. Thanks to his intelligence and insight, Piero was able to recruit many strong and extraordinary individuals, such as Dottore, Signora, and Scaramuccia, skillfully exploiting their ambitions and weaknesses.
Magical abilities. Before the Cataclysm, Piero was the court mage of Kaenri'ah. He tried to warn the ruler and the sages that their experiments with the power of the Abyss could "tear the veil of sin" and incur the wrath of the Archons. Although he was unable to prevent the catastrophe, the very fact of his former mastery of magic is a fact.
The Curse of Immortality. As a purebred citizen of Kaenri'ah, Pierrot suffered this curse during the kingdom's fall. He lived for over 500 years, remaining in active service. However, immortality comes with a caveat: over a long life, the mind can gradually deteriorate (erosion), but Pierrot himself shows no obvious signs of this.
Electrokinesis. Pierrot demonstrated the ability to manipulate the element Electro. In his confrontation with Ronova, he wielded an electrically charged God's Eye (possibly a Caenri'ah cut).
Political influence and strategic thinking. This is perhaps his key "ability" in the grand scheme of things. Piero is the leader of the Harbingers and the right-hand man of the Snow Queen. He personally recruited many key figures: Dottore (Zandika), Signora (Rosalina-Kruczka Loefalter), Scaramuccia, Arlecchino, and Tartaglia. He had an eye for talent and used it effectively.

Piero is the leader of the Fatui Harbingers and one of the organization's founders. He was formerly the court mage of the kingdom of Kaenri'ah. His origins in the destroyed kingdom are confirmed by the unique star-shaped pupil characteristic of the inhabitants of Kaenri'ah.
Appearance details
Height and Build: Pierrot is a tall man with a strong build and a stern, majestic posture.
Hair: Long, grey or ash-coloured, neatly combed back with a few strands falling over the face.
Mask: This is the most recognizable feature. The right half of the face is covered by a black mask with gold engraving and a dark blue insert where the eye should be. The mask likely conceals traces of the immortality curse suffered by the purebred inhabitants of Kaenri'ah.
Eyes: Light blue with diamond-shaped pupils. This feature is a clear sign of Kaenri'ah descent.
Clothing: A long, dark cloak with a high collar and a massive fur ruff. The outfit is in white, dark blue, and gold. On the back, you can see a snowflake symbol, the same one worn by Pulcinella. Pierrot also wears white gloves and tall white boots with gold details.
Additional elements: In the right ear there is a single blue earring.
Height: 187.2 cm.
Age: over 500 years. Biological age: approximately 39–45 years.
Main character traits
Deep bitterness and disappointment. Having experienced the destruction of his native kingdom of Kaenri'ah as a result of the Cataclysm, Piero became embittered against the celestial principles and the gods. He was unable to prevent the catastrophe, despite having foreseen it, and this left an indelible mark on his personality.
Fanatical devotion to the Queen. Piero sees the Cryo Archon as a kindred spirit, sharing his hatred for the existing world order. He serves as her chief advisor and organizer, devoting himself entirely to her plans.
Cold pragmatism. He evaluates people and Harbingers solely in terms of their usefulness in achieving the Queen's goals. His decisions are carefully considered.

Name: Queen (full name) Anastasia Feodorovna Snezhnaya
Region: Snezhnaya
Element: Cryo
Age: Over 600 years old, but looks like a young girl.
Appearance: A girl with cold, icy features. Her skin is pale, almost white, and her long, light-blond hair, with a bluish tint, is carefully styled into an intricate hairstyle, flowing into straight strands that frame her face. She has pointed ears (slightly reminiscent of those of elfs), adorned with a long earring in the shape of a four-pointed icy star with a teardrop pendant. Her eyes are light, with a distinctive icy glint.
Her head is adorned with a massive metal crown of complex geometric design, reminiscent of ice crystals or the jagged edges of an ice crown. On her forehead, just below the crown, is a small decorative element in the shape of a teardrop or diamond. Her face expresses a calm, mysterious, and cold smile.
The girl is dressed in a robe with a fur collar or cape that drapes over her shoulders. She wears long, light-colored gloves. Details of the garment are adorned with crystalline elements reminiscent of icicles or shards of ice. A decorative collar or ornament is visible around her neck, complementing the overall icy image.
Duality. Tartaglia describes her as a "gentle nature" who has been "frozen" by difficult events. That is, deep down, she is still capable of compassion, but is forced to hide it behind an icy mask. Arlecchino also notes her compassion in the past.
Decisive and ruthless in her methods. She doesn't shy away from using force to achieve her goals: she suppresses uprisings in Snezhnaya, reorganizes the state, strengthening central authority. At the same time, the Tsarina is kind to her subordinates.
A distorted understanding of ideals. Although she bears the title of Archon of Love, her interpretation of this ideal is distorted. The Wanderer sees her actions as an attempt to compensate for something rather than genuine feeling. Dainsleif notes that she has no love left for her people—they follow her only because they hope to overthrow the Heavens.
