Her Royal Highness the Tsaritsa is actually a gentle soul. Too gentle, in fact, and that's why she had to harden herself. Likewise, she declared war against the whole world only because she dreams of peace. With supreme rule over Snezhnaya, she uses her loyal followers in the Fatui to manipulate and intimidate the other nations of Teyvat. She is targeting the other Archons' Gnoses for reasons unknown, though it likely relates to her goal of «burning away the old world».
