La Signora, also known as Rosalyne-Kruzchka Lohefalter and by her codename "The Fair Lady," is the Eighth of the Eleven Fatui Harbingers. Five hundred years ago, before she became a Harbinger, Rosalyne was a charming young woman from Mondstadt who studied at Sumeru Akademiya. After her lover Rostam died in the Cataclysm, she became a manipulative and cunning Harbinger for the Fatui. Yet this version of her still has her slight flirtatiousness and charm that leaves striking impressions.
