I was in the Tower the other day and noticed something odd. On the side of one of the pillars you see right at the point where you spawn, there was what looked like a purple triangular rune of some sort. Now maybe it's just me since I rarely stop and actually LOOK at my surroundings in the Tower apart from the breathtaking view of the City and the Traveler, but does anyone else see that rune? Was that always there, or could it be a decorative addition put there in preparation for this year's Festival of the Lost? EDIT: Oh, never mind, I've been informed that it is in fact a sign of Xur's presence. Thank you to those of you who took the time to fill me in.
