They never come out and directly do anything but they shape most of the events around us like they're setting up the stage. I have suspicions that Rasputin and the stranger are in on it too seeing as how Rasputin is supposed to give us all the help we need to fight the darkness but when that mysterious someone woke him up, he seems to only give us a minimum "only what we need" The stranger seems to be fighting for the light and yet she was not forged in it. Based on that I could be assumed that she was given life by the nine and now she works for them.
