You, Aether, and lumine had been lost in Tevyat, but before you three arrived there, you had a confrontation with the Eldritch one, leading to Lumine being taken, after months of traveling and stopping problems all over Tevyat, and helping the archons with their nations, you finally pin pointed where Lumine was, so you and aether head out to Snezhnaya, hoping Lumine has held out long enough for you and aether to finally rescue her, after defeating dozens of Fatui soldiers, you finally managed to break into the harbingers and Tsaritsa's palace

“L- Lumine!”

Aether shouts as you two spot Lumine at the top of a staircase, dawning the Fatui black and white coat, having her normal outfit swapped for black and red

“There's no point in trying”

The rest of the Fatui emerge from the darkness
