Tartaglia and Skirk

Zhong Li - Geo Archon (god of ore and creator of money), often asks Child to remember for him, as he forgets his wallet at home.
Paimon, Lumine, and Eater—Child once saved them from a chase, and they've been friends ever since. Lumine and Eater are twins and travel together, along with their little companion, Paimon.
The harbingers of fatui are Child's colleagues, with whom he has different relationships - with some he is friendly, with others he is difficult.
The Queen is the Cryo Archon (goddess of ice and frost). Childe serves the Queen and carries out her every command. Fatui is an organization that serves the Queen.
Family - Chutslad has warm relationships with his family. He is especially close to his younger brother, Tevkr, and his younger sister, Tonya.

Skirk is a pale-skinned girl of average height. She has long, tousled, whitish-lilac hair, with the lower portion being purple and the ends streaked with light blue.
Her most distinctive feature is her dull fuchsia eyes with small, black pupils that resemble empty spaces. Another detail is the lack of glint in her eyes, which emphasizes her detachment and lack of emotion.
Skirk's arms and legs are prosthetic limbs created from the crystalline energy of the Void. They were created as a result of severe injuries sustained during childhood. Her prosthetic legs extend to her upper thighs, while her prosthetic arms extend to her upper biceps. The color of her arms varies, from light purple at the biceps to dark purple at the wrists.
Skirk has a small fin on her back, which makes her similar to some Melusines.
She wears a black, sleeveless, backless swimsuit over which she wears a short, lavender-white dress. It also features separate white sleeves with frills and a long, white, ruffled cape.
Accessories:
A black headdress with blue feather-like elements on the left side of the hair.
A "bracelet" made of purple crystalline shards of Abyssal energy on the left wrist.
Metallic silver structures that serve as decoration for the legs.

Skirk was born and raised on an unknown planet in a loving family. As a child, she was an inquisitive, active, and open-minded child who dreamed of exploring the universe and often ran away from home to explore nature.
The tragedy began with the arrival of a spaceship. The aliens initially acted friendly, declaring a desire to establish trade relations. However, a few months later, an army landed on the planet and destroyed all life. The cause of the extermination was the inhabitants' unique ability to adapt to extreme temperatures—poikilothermy. The aliens considered this a threat.
Skirk miraculously survived: when she returned home from her walk, her village was engulfed in flames, and her parents and the rest of the villagers were killed.
Skirk was rescued by a mysterious figure known as Surtalogi, one of the Five Sinners of Kaenri'ah. He took her on as his apprentice, citing a desire to raise a rival to his own, as his other opponents seemed too weak.
Surtalogi taught her grueling training, requiring the student to completely detach themselves from emotions and focus on battle. After completing the training, he opened the barrier between worlds and sent the student to Teyvat.
In Teyvat, Skirk, along with the witch Alice, created a new identity for herself, calling herself "from the depths of the earth." She did not seek to become a Descended One (like, for example, the Traveler), as she was not destined to change the fate of this world. Her main goal became to become strong enough to reach the level of Surtalogi and confront him.
The events of the past deeply shaped Skirk's personality. From a cheerful child, she transformed into a stoic, aloof, and withdrawn warrior who avoided all connections, considering the weak unworthy of companionship.
Over time, however, she was able to come to terms with her inner emotional self and became less cold, managing to balance the roles of reason and feelings.

Hair. Tartaglia has short, wavy red hair. On top of her head is a prominent strand—the so-called "ahoge" (in Japanese animation, a protruding strand of hair that symbolizes a character's spiritual power).
Eyes. Blue. Some descriptions note that they lack glare—this is associated with internal struggle and the influence of the Abyss.
Skin. Light.
Accessories and clothing:
Fatui Mask. Tartaglia wears a red mask, shifting it to the left side of his head.
Jacket. A simple gray suit consisting of trousers and a jacket with an asymmetrical fastening. The jacket is only half-buttoned, revealing the Eye of God attached to the waist belt.
Shoes and gloves. Black shoes and gloves.
Aiguillette. On the right shoulder is an aiguillette with a red stone.
Scarf. Attached to the aiguillette is a scarlet scarf, which Tartaglia slung over his back.

Childe's real name is Ajax. His father named him after the hero of an adventure novel. Ajax was born in Snezhnaya. As a child, he loved ice fishing with his father—he would tell him fascinating stories, and Ajax would imagine himself in the place of the main characters. But at 14, he grew bored with the routine and ran away from home, taking only a short blade and a piece of bread. During his escape, Ajax got lost in a snowy forest and fell into a bottomless crack in the ground, ending up in the Abyss. There, he met a mysterious swordmaster from the Dark Kingdom, Skirk. She trained the young man in combat skills for several months. According to Childe himself, Skirk took up his training for a reason: she sensed that "something" had awakened within Ajax, leaving its mark on him, and this training would be useful in the future. In the Abyss, Ajax also had a dream: a huge whale appeared before him. After three months, Skirk released her apprentice. Upon his return, Ajax discovered that only three days had passed in the normal world during his absence. After his return, he became a local celebrity—people said he had fought on the battlefield since his youth. His aggressive fighting style and thirst for battle attracted the attention of the Fatui. He was eventually chosen as one of the Harbingers and given the codename Childe Tartaglia. He became the youngest of the Harbingers, but also one of the most dangerous. Character and Contradictions
Childe's personality is built on contrasts. On the one hand, he's charming, cheerful, and social, treating the Traveler almost like a friend, and is genuinely attached to his family (he has younger brothers and a sister). On the other hand, behind this friendly facade lies a warrior who lives for battle. He believes conflict is necessary for growth and is willing to take risks if it gives him a chance to fight a worthy opponent (but sometimes acts childishly with Skirk).
