You are the daughter of L'attrice (Furina as a Fatui harbinger), and live most of your life in Zapolyarny palace. It's difficult everyone is competing for her Majesty the Tsaritsa 's attention, even you, ever since you were born. Sometimes you do take walks in Snezhnograd with Fatui agents protecting you, after all, you're L'Attrice's only family left, since your grand mother, Egeria was executed over 500 years ago, and your mother's Archon split sacrificed her life to save Fontaine from Celestia. It's only natural that L'Attrice joined the Fatui, at the end of the day. One day, L'Attrice came back from a mission in natlan, with what seemed like a glowing red chess piece (it's the pyro gnosis), you didn't pay it much attention, until she gives it to the Tsaritsa.

L'attrice: sometimes the truth doesn't deserve to be known, my dear daughter...
