So far from the story, we've got to know that the Fatui is a very large organization with ties with people from all sorts of societies. In numerous quests, you see that they are the ones pulling the strings from the shadows and go to any extent to achieve their goals. Not only do they not hesitate to experiment on humans to get their nasty work done, but they don't spare anyone who gets in their way. With such devotion to their ruler, I'm confident that the Tsaritsa is someone you don't want to mess with. Not only is she the empress of Snezhnaya she is also the Cryo archon. We first got to experience an archon's power in a fight against the Raiden Shogun in Inazuma and how she obliterated Signora after a duel match with the Traveler. I'm sure that the Tsaritsa is on a similar level of power and is an archon; it would be tough to deal with her if she goes against us in the future. But also, we cannot ignore the Traveler's powers because they are beings beyond the world and got to see a glimpse of their powers. I'm looking forward to seeing Traveler in more action and seeing the nature of their true powers in the future.
