Vampire Counts and Tomb Kings
Ive been reading the Vampire counts book and the tomb kings armybook. In the VC book it says nothing about Nagash casting a spell to kill everyone in nehekhara (and therefore the magic reawakening the now tomb kings) but in the TK book it says that this does happen. Due to the VC book being newer I would believe this one. This would mean that in the TK book, which I think is out next year, will have to include new reasons for the creation of the TKs.
