Sir Antoine Pfeil is one of the Fallen Knights in Hearts of Stone Expansion for The Witcher 3: Wild Hunt. From Grand Master Ulrich, he was ordered to clean the elven ruins of Kilkerinn of any valuable artifacts, and then burn the place to the ground. Knight however, had a secret arrangement with a connoisseur of art Yaromir. They were agreed that Antoine will sent robbed elven statues, send them to partner and he will sell them to his rich friends like Count Kurt Dysart or banker Rudolf de Jonkheer.
