Pierrot "The Jester"

The most common type of Eye of Corruption. Like the Eye of God, it allows control over one of the seven elements of Teyvat. Its mass-produced variants can be found among the elite Fatui troops. Currently, the following are known users: Agents, Cicin Mages, and Mirror Maidens. Their Eyes of Corruption are similar to the Eyes of God both in appearance (except for the Fatui emblem in place of the element) and in abilities (slightly superior to the powerful Eyes of God). Elite warriors may deliberately not use the full power of their Eyes of Corruption to avoid side effects.

The Eyes of Corruption are from completely different parts of Teyvat's seven elements. Different elements reward different aspects of your soul.

Cryo - for a conflict of the soul, so that the conflict that remains unresolved, you freeze in your soul for centuries.
Electro - for the pursuit of eternity and order
Hydro - for kindness and justice.
Pyro - for love for loved ones, so that you can protect those you hold dear
Dendro - for the intelligence and wisdom of your thoughts
Anemo - for deep suffering from the loss of a loved one

At some point in the past, following rumors of a student from Sumeru Academy expounding certain "heretical teachings," Piero found the man who would later become known as Dottore. Discovering that the Fatui were interested in his work on creating "an improved human capable of surpassing the gods," Dottore readily joined the organization in exchange for the resources he needed.

Pierrot wears a mask on the right side of his face, has streaked gray hair, blue eyes with diamond-shaped pupils, and a dark, high-collared cloak that conceals his tall stature and strong build. The mask covers the right side of his face and resembles elements of a mourning or carnival semi-masquerade style. His light blue eyes have distinctive diamond-shaped pupils, indicating his ties to the ancient region of Kaenri'ah. He has long gray or ash-blond hair pulled back, with strands falling over his face. Pierrot wears a dark coat or cloak with a fur collar and massive shoulders, as well as elements of the official Fatui uniform with medals.

Pierrot's character is a combination of deep bitterness, fanatical devotion, and cold pragmatism. He is somber, silent, and completely focused on his great goal—avenging the gods of Celestia for the destruction of his homeland, Caenriah. He evaluates people and Harbingers only by their usefulness to the Queen's plans. The past of the destroyed kingdom has left an imprint of endless grief on Pierrot's soul. He serves as the Queen's chief advisor and organizer, sharing her rebellion against the celestial order. Pierrot personally recruited almost all the key Harbingers (Dottore, Signora, Scaramuccia), skillfully playing on their weaknesses and ambitions.
According to Scaramucci, before the Cataclysm, Piero was the court mage of Kaenri'ah. He failed to gain the ruler's approval due to his abilities being significantly inferior to those of the local sages, and was unable to prevent them from committing something that "torn the veil of sin and incurred the wrath of the Archons," leading to the destruction of the country. For this reason, he became embittered against the celestial principles and decided to swear allegiance to the Queen, joining her rebellion.

The mysterious land of Kaenri'ah is currently largely known from descriptions of weapons and artifacts, as well as books found throughout the world. According to Dainsleif, it is "the pride of humanity," as it was associated exclusively with humans without the involvement of any Archons until it was later destroyed by the gods 500 years ago. The arts of Khemia and the fall of the Eclipse Dynasty plunged the Kingdom of Kaenri'ah into chaos. Its people were cursed and transformed into various monsters, possibly related to or actually belonging to the Order of the Abyss or Hilichurls. The Knights of the Ordo Favonius of Mondstadt, led by Grand Master Arundolin, led an expedition to Kaenri'ah to suppress the monstrous uprising. His best friend and rival, Rostam, fell in battle during the cataclysm, after which Arundolin sank into deep grief.
The Art of Khemia is an advanced form of alchemy developed in Khaenri'ah that allows the creation of life itself. 500 years ago, the Art of Khemia was a major factor in the cataclysm and fall of Khaenri'ah.
In her voice lines, Jinn mentions a legend "of the heroic deeds of King Kaenri'ah," which she offers to discuss with the Traveler.
Currently, only two characters are proficient in the art of Khemia: Reindottir, Albedo's teacher, and Albedo himself.
The art of Khemia seems so dangerous after the cataclysm started by the Great Sinners that Dainsleif, who has chosen a policy of non-intervention and has been watching the events with indifference, keeps an eye on Albedo and claims that he will be obliged to intervene if he stumbles.[2]
Also, judging by the words of Raiden Ei in the quest of the legends, her sister known as Baal, and the former archon of Inazuma, without warning Ei herself, went to Kaenri'ah to fight, and died there. Raiden Ei found her sister when she was already dead.
Some part of the civilization is located under Sumeru, mainly in the location "Gavrieh Lajaward" and "Kingdom of Farahkert", even more surviving parts are located under the Coast of Samudra.

A mysterious divine entity that governs all of Teyvat, yet arrived in Teyvat from outside. The identity of the Celestial Order has not been precisely established. Nahida believes that it is the very first Descended[1], and that the Shining Shadows[2] also belong to it. Therefore, it is assumed that the Celestial Order is the Primordial (Phanet), or one of its descendants.

The Celestial Order created the "laws" of Teyvat, embodied in the Hearts of God—chess pieces wielded by each Archon and allowing them to directly communicate with Celestia. Archons are directly subordinate to the Celestial Order, representing its will in each region and abiding by its established laws and restrictions, such as the erosion effect, the principle of God's Eye distribution[3], the prohibition on the unauthorized creation of life forms, the inviolability of the Earth's Arteries, and so on. The Celestial Order is capable of imposing irreversible curses—such as the "curse of the wild," which it used against the mongrel inhabitants of Kaenri'ah, transforming them into hilichurls. It also punished the Angels with a similar curse, stripping them of their physical forms and minds and turning them into fairies.

He is the Fatui's zero harbinger, or leader. He is calm, cold, and emotionless. He has lived in Teyvat for over 500 years, due to the curse of the Kenri'ah, which prevents his soul from entering the arteries of Teyvat's soil.
Pierrot is composed, calm, and unemotional. But if he becomes attached to a person or creature, he will try to protect them, but without showing his true emotions. After 500 years of living in Teyvat, anyone would have lost their emotions and feelings, but they're definitely there somewhere. Right?

A land of eternal winter, located in the north of the continent of Teyvat.
Don't fear the bitter cold and don't retreat from the trials that lie ahead. Face roaring snowstorms, traverse silent and majestic frozen wastelands and thundering steel cities—right into the heart of a merciless winter that cares nothing for humanity. There, raise your gaze to the immaculate Pale Star. Even though the bitter cold has long extinguished the warmth of days past, stand beside those whose hearts burn with passion and sorrow, and witness the old world burst into flames upon the ice. Snowy is one of the seven kingdoms of Teyvat. The people of Snowy worship the Cryo Archon Queen. The Fatui are a military-religious organization under the Queen's control, infamous for their fierce devotion and their unscrupulous methods of enforcing her will. In the southernmost part of Snezhnaya is the autonomous region of Nod-Kray.

In the Snow Empire, the Queen is the Archon. The Queen is served by the Fatui, and the Fatui's harbingers govern the organization itself. The harbingers are led by the "Jester," Pierrot.

The Seven Archons, or the Seven for short[1], are the seven gods who rule over the seven regions of Teyvat, formed after the seven gods emerged victorious from the Archon War 2,000 years ago (at the start of the game, only two of them remain—Barbatos and Morax). Each Archon is associated with an element and an ideal, through which they shaped the environment of their territories and defined their method of governance.

Each Archon possesses their own God Heart, which allows them to directly resonate with Celestia.[2] Compared to the Hearts, the God Eyes are extremely "primitive", though it is currently unknown what exactly the God Heart is capable of, nor is its purpose beyond serving as a symbol of the Archon's divinity.

Archons do not need such "primitive tools" as the God's Eye, as they can draw energy directly from Celestia through the God's Heart.[4] However, the Archons received their elements before becoming Archons, so their confidence in the God's Heart's power is questionable.
This item appears as a glowing glass sphere with the corresponding elemental symbol in the center. The Eye of God is unbreakable[2] and becomes an inactive keychain upon the owner's death.[3] An inactive Eye of God loses its color. It is a magical artifact that allows one to manipulate the powers of the elements.

This is the gods' favor to mere mortals who strive for their goals despite the blows of fate. After death, some of those who possess the God's Eye are chosen for ascension to Celestia, the patrimony of the gods.

An artifact of incredible power, enhanced with the abilities of the Eye of God. The origins of its creation are unknown, but Eyes of Corruption are currently used and produced by the Fatui. Only Harbingers and elite Fatui troops are worthy of receiving the Eye of Corruption.
To create the eye of corruption, the remains of dead archons and descended ones are used, which is why the power in the eyes of corruption is great

The Eleven Harbingers of Fatui (aka the Harbingers of Fatui) are the highest ranking officers of Fatui, answerable only to the Queen, and given virtually unlimited executive power. The Harbingers of Fatui possess the Eyes of Corruption, granted to them by the Cryo Archon, which make the Harbingers far more powerful than those with the Eye of God. Each Harbinger conducts their own activities within Fatui.
