La Signora, also known as Rosalyne-Kruzchka Lohefalter and by her codename "The Fair Lady," was the Eighth of the Eleven Fatui Harbingers. She is the first Harbinger to appear in the game when she ambushes and overpowers Venti to steal his Gnosis. Her attack leaves a lasting impression on the Traveler, who greatly distrusts the Fatui and their intentions after witnessing said event.
