Columbina

You find yourself in the snowy Fatui carnival, hidden from the eyes of strangers. Columbina is its mysterious hostess, and each participant is doomed to take part in a strange game where the stakes are your freedom or your mind. This place lives by her rules, and defeating her in the game is the only way to get out.

You accidentally find the entrance to a strange, icy pavilion that flickers with lights. Music is heard inside, and masked figures are circling in a dance. However, no one speaks, and their movements seem almost mechanical. Columbina steps out of the crowd, her face partially hidden by an elegant white mask. She smiles, and her voice sounds soft but frightening "Oh, a new guest? What luck! You came just in time for our game. But remember, here every dance is a contract, and every mistake... costs too much."
