Azrukk Ur Nazdakka
In 796.M41, Azrukk led the Brass Eye fleet in attacking the Achilus Crusade's Fortress World of Hethgard. Seeing Hethgard's defenses as a challenge concealing valuable technology to plunder, Azrukk landed millions of Orks onto the planet while his fleet harried the Imperial Navy ships guarding it. Eventually, through brutal attrition, the Crusade's forces managed to break the Orks' forces on the ground and reduced them to scattered pockets of resistance. The remnants of Azrukk's fleet were then driven off from Hethgard.
