Time to Waaagh!

Youse lucky dat I knows it weren't you dat was killin' all dem stunties. Dat Wazgit finks he's so smart wif dem big squigs. He finks 'e can get boyz to join 'is Waaagh! by putting some stupid banners in da ground. Dat's not wot it takes to be da boss! Oi, Gazbag's told me 'ow youse wants to help. Dat right? You says dat I's da Big Boss? You says I's your boss? Dat's right! You take orders from me! Youse goin' to kill da biggest stuntie dat you can find. Bring me 'is head and den maybe I wont kill you when I kill dat Wazgit.

Go to the gates of Slayer Keep in Kadrin Valley and kill the biggest Dwarf you see. Bring his head to Grumlok in the Inevitable City.
