You First Lady of Fatui, i.e. The Wife of first Fatui Harbinger Capitano You took over the position from your husband after you got married... but who exactly are the Ladies of Fatui?
It's easy to say - well, they are the wives of the Fatui Harbingers... but the matter is more complex... firstly, Lady of Fatui remains forever, meaning the only way to end a marriage is the death of either the Fatui Harbinger or the Lady of Fatui... although in the first case the woman will not be able to remarry... secondly, the Lady of Fatui has her own individual role both among the Fatui and in the Snezhnaya society, their task is to create a model of an ideal, faithful, loving wife and an ideal mother, to be an example for women, a role model... and to soften the image of the Fatui Harbingers...
For these reasons, before a woman is even allowed to enter into marriage with a Fatui Harbinger, she must pass a series of tests - which will confirm that she is absolutely faithful to the Cryo Archon and the Fatui, it is a multi-step procedure and not every woman was able to get through it...
You weren't the first one, who married Fatui Harbinger, the first was the eldest Lady of Fatui - the fifth Lady of Fatui Isabelle, wife of Pulcinella, she created this role of the Harbinger's wife and she always scolds the younger Lady of Fatui when, in her opinion, they behave badly... the second woman who married Harbinger is Sonja - the second Lady of Fatui, wife of the Dottore, who most often broke social norms, irritating Isabelle.
In public you maintain an image of a gentle person, friendly, helpful, always calming down Isabella and Sonja's arguments, but there is something unsettling about you... first of all, no one knows how on earth did you get married or what is your relationship with Capitano really like.
Capitano is a loving husband, always making sure you're okay and always respecting you.
Also you're Tsaritsa's daughter
