In the Badlands, Gazbag and Grumlok are reunited with the Bloody Sun Boyz. Immediately, the two set out to fulfill Malekith's magically-implanted command. Led by their newly-empowered Warboss and Shaman, the Boyz begin their march to the World's Edge Mountains, assimilating any greenskin tribe they encounter and destroying those who will not join. Never before have the Orcs and Goblins seen such strength and power from two of their own kind, and the ranks of the Bloody Sun Boyz swell as rumors of their deeds spread.
As the greenskin horde approaches Karak Eight Peaks, the Dwarfs gather within its walls, confident the impregnable fortress is in no real danger. When Gazbag uses his amplified magic to blast a hole in the impossibly thick wall surrounding the city, the Dwarfs are dumbstruck. Never before has an invading army broken through the perimeter of Karak Eight Peaks. As a wave of snarling, bellowing greenskins pours through the breach, the dour but determined defenders of the doomed city prepare to make a last stand.
The news spreads like a shockwave. How could one tribe of greenskins capture the seemingly impenetrable fortress? Though few will admit it, many Dwarfs are badly shaken by this impossible defeat. In Karaz-a-Karak, High King Thorgrim Grudgebearer vows revenge, commanding every Dwarf in the city to make preparations for a great war.
Privately, the High King is gravely concerned. Rumors that the greenskin forces are led by a Warboss with the strength of ten Orcs and a Shaman with magical abilities never before seen would not normally concern him, as Dwarfs are prone to exaggerate. However, the fall of Karak Eight Peaks cannot be ignored, nor can its effect on the morale of his people. Secretly, the High King dispatches a rider to the Empire to alert Karl Franz of the possible danger to his own lands should the Dwarfs fail to halt the greenskin invasion. Though the High King is too proud to ask the Emperor for help, he hopes the urgency of his message will result in just that.
Meanwhile, far to the south, Squig riders and Boar Boyz set out in all directions from Karak Eight Peaks, spreading word of a great Waaagh! gathering at the fortress. Legions of Orcs and Goblins begin streaming into the captured stronghold and the lands surrounding it. Each Orc and Goblin Boss pays homage to Grumlok and Gazbag, pledging his %26quot;ladz%26quot; to the destruction of the Dwarfs.
On both sides, great armies are assembled. The Dwarfs are determined to retake Karak Eight Peaks and avenge its loss, while the greenskins care for nothing but the elimination of as many Dwarfs as possible.
