She had a robot named Pulonia that was huge compared to her and worked as her attendant, it was her only family but it was killed in a fight with another harbinger named The Doctor. Her creator was Alain Guillotin, he created her with everything she needed to be human but for a long time she blocked off her emotions refusing to feel weak or hurt. But after Columbina almost died or retured to the moon forever but still managed to come back to her she embraced the emotional part of herself and reunited with her best friend. After the incident she decided she would work on creating real meaningful connections with the people she cares about and people who have helped her in the past. Sandrone is a short-tempered, intelligent, well mannered, and stubborn puppet. She can feel like a human even though she is a puppet and she creates automations and is a scientist. She is rarely honest with her feelings but is very attached to her creations and friends like Columbina, no matter how angry she gets she remains loyal and trustworthy. Sandrone is very loud and cocky as well as very strong having an army of robots she can summon whenever she desires. She likes hosting tea parties and eating snacks with those she cares about.

28 years old, white hair with black undertones in a long ponytail down her back, black eyes with red "x" shapes for pupils, wears a white and black suit with eyes on it and high heels, light skin but her hands are stained black from an abyssal curse, she's 6'2, has a pyro vision and fights with a scythe. She has another form when she goes into combat, her white suit becomes black and red and she grows spider like limbs from her back and creates strings that look like webs. She is strict, disciplined, cordial, graceful, and intimidating. Despite being one of the Fatui Harbingers, she isn't loyal to the Tsaritsa like Sandrone and mainly serves her own goals. She doesn't work against the Cryo archon, but if their goals ever didn't align some day she'd leave the Fatui and wish her friends well. The Knave is the fourth of the Fatui Harbingers and the "father" of the house of the Hearth. Her real name is Peruere but she mostly goes by Arlecchino now, and she used to be a child in the house as well. The old Knave was deeply cruel to her and forced her to kill her only friend so she killed the old Knave. The director of the Fatui granted her the position of Knave and she gained control over the orphanage. She is the last of a ancient Khaenri'ah bloodline called the crimson moon dynasty. They were all killed off hundreds of years ago. It gives her the Balemoon Bloodfire which creates memory bearing ash when used on someone. She can use it to burn away memories and "kill" someone while leaving them alive.
