Also, the Tsaritsa is only her demonic name; her real name is Anastasia Fedorovna Snezhnaya, the Cryo Archon.

The main theory is that the Tsaritsa, the Archon of Love, is collecting all the Gnosis to challenge the Celestial Principles and Celestia herself. After the Cataclysm 500 years ago, she became disillusioned with the current state of the world and decided to change it. This is why she created the Fatui and sent the Harbingers to collect the Gnosis of the other Archons.
