So....Nagash did NOT rise from the dead on...what 1111, 666 years after he was killed by Sigmar?...Hrrm...I don't know how I feel about this. It's gotta be a set up. They are going to plan a "Return of Nagash" summer campaign. New 'undead' book that can be used briefly like the Sylvainian Levies in the Storm of Chaos. Maybe a new Nagash model? Arkhan has been scouring the world for Nagash's lost artifacts, so he gets them all together in one spot and Nagash comes back to unlife! And he is so powerful he yokes the tomb king army AND the VC army along with his own limited 'Undead' army (old school Undead). Or perhaps Arkhan is on the verge of raising Nagash back but can not locate his crown, that would draw the OnG in nicely. So yeah the Campaign would be Undead, Vamp, and Tomb Kings vs. the forces of good and OnG. I am sure that the new storm of Magic will leave some sort of clues...I can not see GW rewriting this big a piece of fluff without some means to make a large pile of money.
