Do you believe the nine refers to individuals or more so galactic entities/ groups/ and/or "gods". I recall reading one of the grim card referring to the nine as more so concepts and congregations than individual, and what relation or purpose does xur have to them and act upon if they are not directly controlling him. And is it possible that the stranger is another agent of the nine being she didn't seem to take any side on the light though she seem biased against siding with it?
