We've got to do something to reduce interest in this doomsday cult, but I'm hesitant to take much action until we know more about who is behind this group.
I've had my men place markers around heavily traveled areas in Orgrimmar. Take these posters and set them up where you see the markers. They won't discourage the most determined of seekers, but it's a first step in exposing this cult. The Horde has enough to deal with as it is, without people wilfully spreading lies too.
