Sandrone

Sandrone, also known as "Marionette", is the Seventh of the Eleven Fatui Harbingers and the leader of the Adventurers' Guild. She is a Fontainian puppet and researcher, as well as the creator of Katheryne. She is accompanied by Fagio, her newest personal creation. She was created around 450 years ago by Alain Guillotin in the image of his deceased sister, Mary-Ann Guillotin, and kept Pulonia, his final creation, as her constant companion following Alain's death. She was recently stationed in Nod-Krai to oversee the Kuuvahki Experimental Design Bureau, but was later killed during a confrontation against Dottore after his seizure of the Three Moons' powers. Following the battle, her core was salvaged to be sent to the Fontaine Research Institute, where she was later revived due to the awakening of a Stellar Linchpin. After Pulonia's destruction, she created Fagio to serve as her new companion. Following her public return during the Fontinalia Festival, she has now returned to her duties in Snezhnaya as a Fatui Harbinger. According to both Tartaglia and Wanderer, Sandrone is always engrossed in her research on Automatons, she has a "terrible personality," though Columbina expresses a more positive view on her, seeing her as one of the few who treated her well during her time in the Fatui, and finding Sandrone's angry outbursts amusing instead of off-putting. Following her interactions with the Traveler and Columbina, Sandrone showed more concern for her friends, which Dottore noted was uncharacteristic of her. She seems to have had a more caring and concerned personality at least when Alain was alive. After accepting her emotional side, Sandrone becomes more honest with herself. She dislikes losing and often has numerous backup plans to use as failsafes. Sandrone is remarkably similar to a human; her body bleeds, and she is capable of touch, taste, and smell. She doesn't merely measure the ambient temperature around her, but can feel it.
