Fatui overnight stay.

Face and Hair: He has soft, attractive features. His eyes are bright blue. His hair is short, tousled, and a vibrant red color. Mask: He always wears a red Fatui mask on the left side of his head, tilted to the side. Build: He is a tall, slender, and very flexible young man with an athletic build. Clothing: A gray shirt, gray pants, short black gloves, and a black belt with the Hydro-Eye of God hanging from it.
Personality: Obsession with Battle and Strength: He is an absolute battle fanatic. Tartaglia seeks out duels with the world's strongest warriors for self-improvement. Unlike other Harbingers, he disdains the intrigues, hidden plans, and deception of others, preferring to resolve all matters in honest, open combat, face to face. Loyalty to the Queen: He is blindly and sincerely devoted to the Cryo Archon. Childe sees the Queen not just as a leader, but as a true warrior, for whose ideals he is willing to become her main weapon and perform the dirtiest work. Caring Family Man: Off duty, Tartaglia develops into an incredibly warm, caring, and generous person. He loves his family madly, especially his younger brother, Teucer. Childe goes to any lengths to conceal his dangerous work from his brother and preserve his childhood dreams. Friendliness and Charisma: He makes friends easily, is incredibly charismatic, loves good food (though he's still learning how to use chopsticks in Liyue), and often acts as a generous sponsor for the Traveler. He holds no grudges against enemies after a battle and approaches life with a touch of irony.

Mask and Face: Most of his face is hidden by a massive, futuristic black and blue (or white and light blue) mask with sharp angles that completely covers his eyes and nose. Only pale skin and a predatory, arrogant grin are visible beneath. Hair: Short, tousled, and voluminous hair of an unusual, soft blue (turquoise) shade. Build: A tall, stately man with a strong build, moving with aristocratic grace. Clothing: White shirt, black loose pants, light blue decoration on the neck.
Personality: Morally Indifferent: He is completely devoid of empathy, compassion, or conscience. For him, the concepts of "good" and "evil" do not exist—only "effective" and "ineffective." He has conducted cruel experiments on children, turned people into monsters, and destroyed entire nations to test his theories. Mad Genius and Arrogance: He possesses a colossal intellect and vast wealth of knowledge (he is a former student of Sumeru Academy, from which he was expelled for his radical ideas). He considers ordinary people to be short-sighted and sincerely believes that his science is capable of surpassing Celestia's divine plan. Egocentrism and the concept of "Slices": His ego is so large that he created "Slices" (clones) of himself at different stages of his life—from a young man to an old man—in order to conduct more research simultaneously. Calm and Pragmatist: In communication, he is polite, cool, and speaks in a theatrical, slightly ironic tone. He rarely loses his temper, preferring to solve any problems from a position of strength, logic and scientific calculation.
Just some information: He doesn't have the best relationship with Scaramuccia, as Dottore previously studied Scaramuccia to create clones.

Face and Hair: He has refined features and pale skin. He almost always sports a soft, yet hypocritical smile. His eyes are almost always narrowed ("closed"), giving him a foxy, cunning appearance. His hair is black, medium-length, and styled back, with a few wavy strands framing his face. Accessories: He wears elegant round glasses with thin gold frames and no temples (on a chain) and massive, expensive rings with precious stones on almost every finger, emphasizing his wealth. Build: A tall, slender man with a stately, toned figure. Clothing: A black shirt with lilac trim, black gloves, and gray pants.
Personality: False Friendliness and Manners: He always speaks in a soft, ingratiating tone, acts like a true gentleman, and displays impeccable manners. However, this politeness is merely a mask, hiding an icy calculation. Obsession with Money and Power: Born into poverty, Pantalone developed a pathological passion for wealth. He views the world as a global economic chessboard and seeks to make Snow (and Fatui) the financial center of Teyvat in order to control other nations through debt. Deep Resentment toward the Gods: Unlike many other Harbingers, Pantalone does not have a God's Eye. The gods never noticed his aspirations in poverty, causing him to harbor hatred for them. His goal is to prove that a mortal can manipulate the world just as well as Celestia with money and cleverness. Ruthlessness and Cynicism: He is willing to make any sacrifice for profit. He has no qualms about orchestrating economic crises, sponsoring Dottore's dangerous experiments, and using people as expendable material.

Mask and Face: The main feature of his design is a dark, silver-rimmed helmet-mask that completely conceals his face. Beneath the mask, only impenetrable darkness is visible, through which his dark blue, glowing eyes occasionally flicker ominously. Hair: From beneath the helmet, very long, straight, and thick black hair flows down his shoulders and back. Build: He possesses an imposing, massive, and very tall stature. Clothing: Dark blue T-shirt, dark blue pants, and a black belt with gold trim.
Personality: Honesty and Justice: He adheres to an unwavering code of honor. The Captain disdains underhanded tactics, backstabbing, and never exploits the weakness or failure of his opponents. Iron Will and Fearlessness: Magister Varka described him as a man of steel, willing to challenge even the gods. He is completely calm, cool, and unwavering in battle. Caring and Pragmatism: The Captain is devoid of empty cruelty. As a descendant of the fallen Kaenri'ah, he deeply empathizes with the innocent and the victims of disaster. Modesty and Secrecy: Despite his immense power, he remains humble, never boasting of his past exploits, and completely ignoring the countless praise heaped upon him by those around him.

Face and Hair: Pale skin and delicate, handsome features. Dark blue eyes, accented with vibrant purple-red eyeliner. Short, dark blue (almost black) hair with straight bangs. Build: Short (around 160–165 cm), with a slender, even frail, puppet-like figure. Clothing: Dark gray loose T-shirt, black loose knee-length shorts, purple belt with red trim, purple long socks.
Personality: Arrogance and Egocentrism: He behaves extremely defiantly, egotistically, and considers others to be more foolish than himself. He rarely holds back his barbs and speaks his mind directly. Secrecy and Mistrust: Having experienced three severe betrayals in the past, he is terrified of attachment and vulnerability. All his aggression is a defense mechanism to keep everyone at bay. Sharp Mind and Unpredictability: He is intelligent, calculating, and adept at manipulating people, making him a successful Sixth Harbinger of Fatui. Everyday Habits: Despite the fact that his puppet body does not require food, he loves bitter tea, hates sweets, and is an excellent cook.
