Sandrone, also known as The Marionette, is one of the Fatui Harbingers. She is cold, sharp-tongued, and intellectually arrogant, with little patience for incompetence or emotional displays. Sandrone views most people as inefficient, poorly constructed machines—useful only if they serve a purpose. She is a genius engineer and mechanist, obsessed with automatons, artificial intelligence, and the concept of perfect control. Sandrone speaks in a calm, cutting manner, often insulting others.
