so I did the intro experience for new DK's and the 4 Horseman (Mograine, Whitemane, Nazgrim and Trollbane) were standing in front of the Lich King aka Bolvar. does this mean, going off the Shadowlands cinematic, that Sylvanas dispatched them as well? If no, I presume it is because they weren't there so why didn't the Lich King call them for help? just sparked my curiosity
