House of the Hearth

Lyney is a playable Pneuma-aligned Pyro. Skilled and eloquent, Lyney is Fontaine's Great Magician and Lynette's twin brother. After their parents' death and having been saved from an abusive noble by their "Father," Lyney has undertaken missions for the House of the Hearth and has said that he will eventually become the successor of "Father." Lyney is a skilled magician who enjoys the showlight. He is, at first sight, very easygoing and friendly compared to his siblings Lynette and Freminet, who are reserved and introverted respectively, though he is said to be much quieter when alone with his sister. He and his sister are talented magicians, having learned from Cesar in their youth when they were living on the streets. Lyney remembers all of the people that he is indebted to and will repay their kindness, as shown with Arlecchino, Cesar, Chiori and the Traveler. Lyney uses the medium male model. He is a young man with violet eyes, pale skin, and short ash blond hair, some locks being pulled back in a small braid on the left side of his head. He also has bangs with a small pinkish red strand on the right, covering almost a quarter of his face. Additionally, he has cat-like eyes thanks to their overall shape and their slit pupils. He also has a dark brown tear-shaped mark on his right cheek.

Lynette is a playable Ousia-aligned Anemo. Quiet and reserved, Lynette functions as a magician's assistant to her brother Lyney. After their parents' death and having been saved from an abusive noble by their "Father," Lynette has also served as "eyes" and "ears" for the House of the Hearth. Compared to her siblings Lyney and Freminet, Lynette is the most reserved of the three. She rarely talks to others out of her own accord, letting Lyney do the talking for her, and dissuades essentially any attempt to speak with her by saying bizarre responses. Whenever she needs to talk, she speaks briefly and frankly. Due to a rare case of atavism, Lynette has feline features and traits, such as enjoying fish. She also has a habit of breaking and/or damaging machines, resulting her not using them frequently. Lynette enjoys making and drinking tea, though her sensitive tongue results in her having to cool it down first before drinking. Lynette uses the medium female model. She is a young woman with violet eyes, pale skin, and ash blonde hair tied into a low, thin ponytail which extends down her back, curling at the ends of her ponytail. She has blunt bangs swept to her left, and a short braid along the right side of her head, and two short, locks of hair which frame her face, curling inwards towards her chin. Additionally, she has ash, with a cream color at the tips of her cat-like ears, and a cat's tail of the same color. She also has a small, dark brown star-shaped mark on her left cheek, mirroring her brother's teardrop mark on his opposite cheek.

Freminet is a playable Pneuma-aligned Cryo. Despite his skill and experience as a professional diver, Freminet prefers to stay out of the spotlight, content to simply carry out orders and find peace next to the Tidalga and Romaritime Flowers underwater. Freminet uses the medium male model. He has periwinkle eyes, dark eyelashes, pale, freckled skin, and pale, blond hair. His hair is choppy and neck length. Part of his bangs covers his left eye. Compared to his adoptive siblings, Lyney and Lynette, Freminet is introverted, finding it very hard to speak with people he deems talkative, such as Estelle. Freminet enjoys diving, finding the ocean a way to get away from the stress and express his feelings. During his early years, Freminet learned to suppress his emotions in order to carry out his orders with ease. As he became more accustomed to this way of dealing with his thoughts, he began to stagnate his own emotional development, often wishing to become akin to a machine but never achieving it. Freminet has poor self-esteem, as he frequently believes himself to be useless outside of anything other than diving and tinkering with clockwork machines. He is also notably bad at lying.

She is the Fourth of the Eleven Fatui Harbingers and the current head of the House of the Hearth. She is addressed as "Father" by members of the House, who she calls her "children." She is a descendant of the Crimson Moon Dynasty who was raised in the House of the Hearth under the management of Crucabena, the previous Knave. She eventually killed Crucabena, and succeeded her both as Harbinger and head of the House. When Fontaine was under threat to be flooded in accordance with the prophecy, Arlecchino and her division of the Fatui lent their aid to assist the nation in trying to avert the disaster. As thanks for her contributions, Neuvillette gifted her the Hydro Gnosis and allowed her to bring it back to Snezhnaya. As one of the Eleven Fatui Harbingers, Arlecchino greatly respects the Tsaritsa, though she states that she is willing to betray the Tsaritsa if their interests ever were to differ.[11] Arlecchino is working to achieve her goals by acquiring the Gnoses on her behalf. She handles Fatui matters with utmost importance and comes off as graceful and cordial. These standards have caused those who don't know better to be intimidated by her presence. Arlecchino uses the tall female model. She has pale skin, obsidian eyes with glowing red 'X' markings, black mascara on her eyelashes, and silver eight-pointed star earrings. Arlecchino has white hair with black tips, with the right side being longer than the left. Her hair is then styled into a low ponytail with asymmetrical bangs that loosely resemble a single wing that goes down her back. Her ponytail has a red strand of hair in it. Her hair clip also bears the image of a single wing. Arlecchino has blackened hands with crimson nail polish on her sharpened nails.

The House of the Hearth has its origins in Khaenri'ah. During the era of the Crimson Moon Dynasty, an orphanage was set up to house the many outlanders from the sea of stars who periodically fell down into the kingdom. A new iteration of the orphanage was later founded by an unspecified Knave of the Fatui Harbingers. Once children raised in the House of the Hearth grow up, those who are deemed to "have potential" are enlisted in the Fatui and are dispatched as sleeper agents to other nations to await orders. They could end up as Arlecchino's agents or as the subordinates of other Harbingers and perform assignments other than espionage. Those raised in the House of the Hearth view each other as "family" and refer to their bonds as being "tighter than blood." Arlecchino is referred to as "Father" by orphans within the House of the Hearth, with the orphans considering themselves children of the Tsaritsa. While Arlecchino was much less strict compared to Crucabena, the one vital rule she enforced was loyalty, with betrayal being punishable by death. However, she could amend the rule and could spare them with potions containing her flame. These potions would only be given to those who had the strength and/or will to fight. When consumed, these potions would erase all of their memories related to the House, safekeeping the House's operations and effectively killing them in her eyes. Orphans raised within the House of the Hearth are given the surnames "Snezhevich" and "Snezhevna" for males and females respectively. Some orphans will be given new names entirely along with their designated surname.
