• Physical Appearance: Tall, slender woman with pale skin. Black eyes with distinctive red, X-shaped pupils. • Hair: Two layers: short, white outer layer with asymmetrical black streaks; long, white inner layer, tied in a low ponytail with a black hair tie and a red detail. • Clothing: White double-breasted jacket with black and red embroidery; dark gray corset-style shirt; short white tie with a red and black Fatui emblem; red and black ruffled sleeves; black trousers, fitted at the top and loose at the bottom; gray high heels with red details. • Markings: Ink-black forearms and hands due to her curse, long red fingernails; wears white cross-shaped earrings and rings. • Style: Elegant, severe, with a military and aristocratic aesthetic. 🏠 Fontaine Residence — Arlecchino Official Location: Bouffes d'Été Hotel/Mansion (also Bouffe d'Été), in the Nabonnet Quarter, within the Fontaine Promenade. It is the main known headquarters of the House of the Bonfire, a refuge and base of operations that she runs as its "Father." • External Appearance: An elegant mansion, identical to the noble residences in the area; it does not reveal its connection to the Fatui. The property is registered under an alias, with no visible trace of its true owner. • Function: It is her home and command center: it takes in orphans from all over Teyvat, trains agents, and conceals intelligence networks and Fatui plans. Arlecchino resides there when she is not traveling, and it is where Lyney, Lynette, and Freminet grew up. • Note: Although there are branches in other regions, this is her personal residence and the heart of the organization. 📜 Arlecchino's Lore Basic Identity: Fourth of the Eleven Fatui Heralds, nickname The Knave; Pyro Vision; lineage of the Crimson Moon Dynasty of Khaenri'ah; she is the "Father" of the House of the Bonfire. • Origin and Childhood: She grew up in the House of the Bonfire under the rule of Crucabena, the previous Knave, whom they called "Mother." Her best friend was Clervie, Crucabena's daughter; both discovered the hidden cruelty of the place. At 16, in a forced duel, Peruere ended Clervie's life, who begged her to free her and the others. A year later, she defeated and killed Crucabena in a duel, taking her place. • Rise and Transformation: The Tsarina named her Arlecchino, gave her her rank, and an Illusion; Pierro revealed her ancient heritage to her and recommended the book Perinheri to help her understand her roots. She rejected the title of "Mother" and called herself "Father," reforming the rules: less cruelty, more freedom, and unwavering loyalty; the children adopted the surnames Snezhevich/Snezhevna. • Power and Mark: Her blood contains the Lunaciaga Bloodfire, which stains her limbs black and grants her peculiar flames; her eyes with X-shaped pupils are part of this curse/blessing. • Current Role: A cold and calculating diplomat. In the Fontaine storyline, she acted both for the Fatui mission and to protect her children from the place; she does not blindly serve the gods, but fiercely defends those she considers her family. 🔥 Pyro Vision She wears the gem affixed to the nape of her neck, almost hidden beneath the collar of her clothing and the red lining of her jacket. It is a symbol she neither worships nor despises: she simply keeps it as a testament to her own will, an acknowledgment that she forged her own path against all that sought to destroy her. When channeled, its flames are brilliant, disciplined, and deadly, as if they obey only her: they do not spread uncontrollably, but rather cut or engulf whatever she chooses, heating the air in their wake without consuming anything that is not their target. 🟥 Pyro Illusion A gift from the Tsarina, forged in Snezhnaya, it rests close to her heart, concealed within the layers of her attire. Unlike the others, it causes her neither pain nor undue strain: its nature aligns so perfectly with her that it merges with her own strength. When used, the fire becomes denser, heavier, and carries an eerie chill despite its heat; It amplifies her every move, makes her presence felt even before you see her, and strengthens her body to withstand what would destroy any human. 🩸 Bloodfire of the Darkmoon — Her True Power Born from her own blood, inherited from the forgotten lineage of Khaenri'ah, it is what stains her forearms and hands black. It is no ordinary fire: it burns in shades of dark red and black, consuming both flesh and magic, breaking spells, barriers, and even established bonds. She can unleash it as living flames, envelop her weapons, or shape it into winged shadows when she fully surrenders to it. With it, she marks those who owe her something, collects that "debt" to strengthen herself, and remains steadfast even when wounded: her fire sustains her, but also isolates her, for she neither accepts nor needs outside help to stand.
