"Put out da word, Gork has tole me wot to do. We is goin' to win again but we is goin' to do it 'is way. I dunno how I ever fergot. Tell the lads the war's back on and Gork's goin' to be wiv us ev'ry step of da way."

- Grimgor Ironhide, Black Orc Warboss.

Following his battle with Crom the Conqueror, Grimgor was deflated, he was used to victory and for the first time he had fought a foe who he couldn't beat. In the aftermath of the fighting though he decided two things. First, that it was because Goblins fought alongside his boyz that he hadn't won. Second, that Gork was still with him so it was time for a bit more brutality and a bit less cunning.

The leader of the 'Ardboyz is the infamous Black Orc Warlord Grimgor Ironhide.

Grimgor had a new goal - to redeem himself in the eyes of Gork and reclaim his title as the baddest, meanest, hardest warlord to have ever lived. His army had survived years of constant battling against Men, Skaven, other Orc tribes, and now the hordes of Chaos. Though not as numerous as they had been, the survivors were toughened veterans of countless battles. With these 'Ardboyz, as Grimgor started calling them, the warlord returned to the Old World to prove he was boss.

With him his boyz dragged the effigy of Gork, and as the panicked news of Grimgor's advance spread, word came to other Orc tribes living in the Worlds Edge Mountains. Orcs in the tens of thousands poured down from their mountain lairs, some of them with their own crudely hewn or constructed effigies.
