Space Wolves - The Wheel of Fire: The target for this first campaign undertaken with his Legion had been carefully selected in council with the Emperor and Horus, and would prove for the VI a true  test of its mettle. Their target was a sector of the expanding frontier known as the "Wheel of Fire," to the galactic east of the Segmentum Solar. It was a sprawling wilderness of erratically transiting star systems and burning nebula, wracked by frequent ion and Empyreal tempests and home to at least a score of xenos-occupied worlds, many under the dominion of the Orks, and thereby a source of periodic drifting Space Hulks and marauder attacks into the nascent Imperium. Human occupation in the region was scant, viable resources few and the cost of pacification projected to be high. For this reason the Wheel of Fire had so far been left alone save for a few probing raids, but now the Great Crusade sought again to expand towards the far larger and more dangerous prize of the worlds beyond Seraphina, an area itself controlled by a vast Ork empire. The threat of the Orks of the Wheel of Fire attacking at the Great Crusade's back in support of their kind was a real one, and to negate that threat, the VI would take the Wheel of Fire and purge it, regardless of any cost they would pay.One of the more notable engagements of this campaign took place at this time. This was a massive joint-Compliance campaign that included multiple Legiones Astartes, including the Iron Warriors and the White Scars, as well as thousands of troops of the Imperialis Auxilia and substantial Mechanicum assets. They were charged with the eradication of the massive Ork horde of WAAAGH! Mashogg. Legends record that it was the Primarchs Leman Russ and Jaghatai Khan who routed the Orks of Overdog Mashogg's WAAAGH!, while Perturabo was featured only as the "comrade" who calculated the optimum way to bypass Mashogg's low orbital defences.For five standard years the war went on, never letting up in tempo, never abating in fury. Casualties for the Legion both in terms of warriors and in ships were frighteningly high, with almost a full third of the Legion destroyed before it was done and the Wheel of Fire left a graveyard of its war dead. Of the many slain were included the increasingly unstable Commander Enoch Rathvin, crushed in the hydraulic claws of an Ork hell crawler while leading a suicidal charge on Xyat. But for every Astartes who fell, hundreds, perhaps thousands, of Orks perished. This was war without quarter, war without relenting; it was not an act of conquest, but of extermination, and was carried out with a ruthlessness and indefatigability that no unaugmented human could have maintained. It was what the VI Legion had been made for, and on the Wheel of Fire, just as Russ had promised, it was re-forged anew.The old enormities and excesses of which the VI had been accused were themselves made good under Leman Russ. Its blood lust controlled with discipline and iron will, and its rage shackled by duty and oath-sworn loyalty, Russ gave his Legion pride in what it was, pride in the power it wielded, pride even in the monstrous violence which lurked within its heart, but with all this he did not allow them to crave glory for its own sake, nor wallow in the bitter poison of mindless bloodshed. He gave them purpose and he gave them honour, bleak as it was. They served the Emperor and that duty was a sacred one; they were made to be the fangs fastened around the throat of humanity's foes. Just as on Fenris, war was ever slaved to the survival of kith and kin, the galaxy would be made a safe and secure home for human life, even if the Wolves that Stalked the Stars had to wash it clean in blood first.
