Carthia van Canten

Carthia van Canten, also known as Cantarella and Sasha, was the mistress of Vattier de Rideaux, the head of Nilfgaardian intelligence for Emhyr var Emreis. She was informing Assire var Anahid about Vattier's intentions. She had an excellent memory, a lively intelligence, and a mercurial wit.

Carthia van Canten appears at the Passiflora in Novigrad where she partakes in a high-stakes gwent tournament under the pseudonym Sasha.

During the event she offers Geralt a deal in which they will split the winnings. It turns out her participation in the tournament was a cover to allow her to gain enough money to travel back to Nilfgaard after her cover is blown.
