Sandrone is the Seventh Harbinger of the Fatui, operating under the codename "Marionette." She's currently based in Nod-Krai running the Kuuvahki Experimental Design Bureau, and she's almost never seen without Pulonia, a heavily modified Ruin Machine that serves as her constant companion.
She's a young woman with pale skin and blue-grey eyes, medium height with beige hair styled in a braided bun and loose strands framing her face. Her whole aesthetic leans heavily into a doll-like appearance—probably intentional given her Harbinger title. She wears an elaborate white dress with red ruffles and a fitted black corset marked with a triquetra symbol set in rubies. The dress has a formal black collar with gold trim and a pear-cut ruby, paired with long white sleeves layered under shorter puffy dark ones. White V-neck gloves, white stockings, and black heels complete the look, plus a fancy white and gold bonnet decorated with red lacing and black bows. There's also a visible wind-up key sticking out from her back—very on-brand for someone called the Marionette.
She's also registered with the Adventurers' Guild, which is a somewhat unusual detail for a Fatui executive.
