The End Times have come. Archaon Everchosen marches on the city of Middenheim, and if he captures it, the key to the Chaos gods' ultimate victory will be his. The last heroes of men, elves and dwarfs gather to stop him, but to stand against the hordes of the Ruinous Powers, they must turn to darker allies. Against all reason, the last hope for the world may be the Undying King, Nagash himself - if he and the mortal races can find common cause and work together. If they cannot, Archaon's plan will come to fruition and the world will be consumed by Chaos.
