Book excerpt: Nagash revives an ancient grudge with the God-King Sigmar as a ferocious new war between the living and the dead shakes the Mortal Realms. The Mortal Realms tremble with unending war. In Shyish, the Realm of Death, an ancient evil stirs, sensing opportunity. Nagash, the Undying King and God of Death, sets his gaze upon the citadels of the living and the servants of Sigmar, the God-King of Azyr. Allies once, joined together against the machinations of the Ruinous Powers, the two gods now find themselves enemies. Nagash, burning with the need to avenge an ancient slight, calls forth his soulless legions to sweep across the realm he claims as his own and reassert death’s dominion over all things, as the War of Heaven and Death begins anew.
