At the End of Times everybody
However Nagash, Sigmar and Arielle (doesn't she rule the Realm of Life?) all make appearances in the Age of Sigmar.
Originally I believed that all the incarnates survived (or were resurrected) and became guardians of their realms but now I recognize various Lizardman heroes.
Who survived the End of Times (or at least made it to the Age of Sigmar) and for a bonus point... how?
