The Ork charged back to the Goff fort and smashed his way into Krugg’s ramshackle hut, knocking the Warboss from his feet with a roar of challenge. The Tyrant fought back with savage brutality, battering Grukk bloody. The two Orks tore the fort apart in their struggle, and eventually Krugg caught Grukk with a thunderous backhand blow of his saw-fisted power klaw, hurling his brutish challenger through a mudbrick wall into the dusty courtyard beyond.
