She is the Seventh of the Eleven Fatui Harbingers and a member of the Adventurers' Guild. She interprets all phenomena through the prism of mathematics, and is an elegant lady who is never absent from a tea party.
She was created by Alain Guillotin in the image of his deceased sister, Mary-Ann Guillotin, and keeps Pulonia, his final creation, as her constant companion following Guillotin's death.
Sandrone, also known by her surname Guillotin and codename "Marionette," was the Seventh of the Eleven Fatui Harbingers and a member of the Adventurers' Guild. She was a puppet created by Alain Guillotin in the image of his deceased sister, Mary-Ann Guillotin, and keeps Pulonia, his final creation, as her constant companion following Guillotin's death. She was recently stationed in Nod-Krai to oversee the Kuuvahki Experimental Design Bureau. She was killed during a confrontation against Dottore after his seizure of the Three Moons' powers, and her core has since been salvaged to be sent to the Fontaine Research Institute.
Sandrone is a young, pale-skinned woman of medium height with blue-grey eyes. She has beige-coloured hair tied back in a braided bun with two long strands framing her face.
She wears a long white dress with red ruffles and a black corset with a triquetra symbol in the middle, with ruby-red gemstones in the spaces. Her dress features a black collar with gold accents and a pear-cut ruby-red gem, and long white sleeves, with short, dark, puffy sleeves over them. Her gloves are white and form a V-shape at the wrist. She wears white stockings with black heels. Upon her head is a white, black, and gold bonnet with red lacing and black bows on the sides. A puppet wind-up key protrudes from her back.
