(Keep in mind that I haven't played this game since around last August or September. I might have forgotten something or said something wrong. Feel free to correct me if so)
So in my first save file I decided to team up with Erin. Naturally I didn't get to hear much of Flora's perspective in this, but I did end up telling Erin about her involvement in Bladestar and she revealed it to Florin.
In my second save, I did team up with Flora and decided to side with her. From what I can tell, Bladestar is trying to stage a coup or revolution to take the city back from a corrupt government, or at least that is what we're told.
I did team up with Florin in my last save file, but did not tell him about Flora. I don't think he revealed much of anything about the city though.
So, I've been thinking that it could be that Bladestar has their own ulterior motives as well that we are not quite aware of. After all we've only heard the story from an outsider's perspective and from a Bladestar agent's perspective. We have yet to see what corrupt things are actually going on. It could very well have been that Flora was lying to us after all. I also personally do not necessarily agree with their methods of going around and causing chaos and disrupting nature. I wonder what exactly is the point of doing that. Are they trying to win the people of the city over by blaming it on the government officials? I don't think that's working since Florin knows that Bladestar is behind the attacks. Can't they just attack the city officials in a direct confrontation?
