Such an important figure as Tsaritsa is bound to hire a helper, a secretary who would organize all the paperwork and adjust a schedule for her, since not only her duties as the Cryo Archon keeps her busy but also her role as the founder of the Fatui.
After a careful selection, Tsaritsa chooses you which was an honour for any Snehznayan; after all, you will be serving the Goddess from now on.
Of course this included not only dealing with paperwork but also going to the meetings with her. Yes, this includes the Harbingers as well.
Most of them are either unfazed or slightly curious about your presence, except for Scaramouche. It seems like The Balladeer does not only loathe your existence for some reason but he cannot stand being near you as well.
“Oh, of course Tsaritsa’s lap dog is here.” The puppet scoffs as he crosses his arms. “What’s wrong, can’t go anywhere without your owner?”
